ios搭一个简易计算器（利用masonry布局）
最后更新于：2022-04-01 10:06:47
这几天学习masonry，搭了一个计算器的界面，的确很简单方便，本着新手的认学态度，索性把计算器功能做出来，没想到啊，新手就是新手，弄了三天才算有所小成。代码放出来给大家参考一下，有不足之处还请留言教我。废话不说，下面上代码
~~~
#import "MainViewController.h"
#import "Masonry.h"
@interfaceMainViewController ()
{
UITextField * utf;//输出数字的
UIButton * btn;//按钮部分，不包括数字0
UIButton * btn1;//按钮：数字0
UILabel * line;//按钮间的分割线，布局用
NSString * a;//接收输入的数字，进行拼接用
NSString *b;//接收输入的小数点“.”，控制数字的小数点的个数用
NSMutableString * c;//计算器有删除数字功能，c来接收数字的删除结果
NSString *result;//计算（+ - * /）的结果
}
@end

NSArray * num=@[@"AC",@"exit",@"<-",@"÷",@"7",@"8",@"9",@"*",@"4",@"5",@"6",@"-",@"1",@"2",@"3",@"+",@"",@"",@".",@"="];
//下面我是用了masonry来进行界面布局，关于masonry的使用请百度或者github，这个东西来布局整个界面我只用了四十行代码，不得不说，很好很强大。
utf=[[UITextField alloc]init];
utf.backgroundColor=[UIColorcolorWithRed:0.222green:0.216blue:0.223alpha:1.000];

make.top.mas_equalTo((64+100)+(i/4)+(i/4)*(S_y-64-100)/5);
make.left.mas_equalTo(((S_x-3)/4)*(i%4)+(i%4));
//因为整个按钮都是固定大小，而数字0我希望他是大小为2个普通按钮的大小，所以我把btn。tag=16和17两个按钮隐藏，此处覆盖上定制的btn1的title为数字0的按钮
if (i==17 || i==16) {
btn.hidden=YES;
}
}];

//下面的两行代码 可以使输入数字拼接，但是需要注意，如果计算器有归零功能，点击之后数字归零，再继续输入数字会接着0输出，类似，189归零是0，接着输入213会成为0213，此时需要将最前面的0消失，所以有上面的那一行代码

//以上这些，可以实现基本的加减乘除运算，并且小数点只能输入一个，有退格和归零功能，在网上查看了其他一些大神的代码，感觉不是很容易懂，作为新手，我能做的只有这些了。。。希望对大家有所帮助，整个代码加起来也就200行不到的样子，其中masonry的应用可能有的人不太熟悉，建议花时间去了解一下。另外对按钮点击事件的判断处肯定有没想到的地方和没做好的逻辑处理，毕竟是一个简易的demo。拿过去复制粘贴就能运行了。记得先装第三方的masonry包哦！
这个是效果图，不喜欢的同学可以将按钮背景图片去掉，就可以看到masonry编辑界面的效果了，记得去掉背景图片后将self。view的backgroundcolor设置颜色，这样看的效果才会明显,类似下面这样的
iOS中添加UITapGestureRecognizer手势识别后，UITableView的didSelectRowAtIndexPath失效
最后更新于：2022-04-01 10:06:44
用TableView写了一个登陆界面，帐号和密码两个Cell中加入了TextField。由于想在TableView的空白处点击时收起键盘，所以他注册了一个UITapGestureRecognizer来识别手势。
ViewDidLoad中注册手势的部分代码如下：
~~~
UITapGestureRecognizer *oneTap = [[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(hideKeyBoard)] autorelease];
oneTap.delegate = self;
oneTap.numberOfTouchesRequired = 1;
[self.view addGestureRecognizer:oneTap];
~~~
其中hideKeyBoard方法就省略了，基本就是几个resignFirstResponder。
然后发生了一个奇怪的现象，点击“找回密码”那一栏时没有反应了！！！
调试后我发现委托方法
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath*)indexPath不执行了。
目测原因是UITapGestureRecognizer截获了touch事件，导致didSelectRowAtIndexPath方法无法响应。
查阅了相关文档后找到了一种可行的解决方法：重写UIGestureRecognizerDelegate中的
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch方法。
~~~
#pragma mark - UIGestureRecognizerDelegate
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch
{
// 输出点击的view的类名
NSLog(@"%@", NSStringFromClass([touch.view class]));
// 若为UITableViewCellContentView（即点击了tableViewCell），则不截获Touch事件
if ([NSStringFromClass([touch.view class]) isEqualToString:@"UITableViewCellContentView"]) {
return NO;
}
return YES;
}
~~~
再次调试，这回didSelectRowAtIndexPath响应了，解决UITapGestureRecognizer手势截获Touch事件的问题！
ABPeoplePickerNavigationController系统通讯录使用
最后更新于：2022-04-01 10:06:42
## iOS：ABPeoplePickerNavigationController系统通讯录使用
昨天因项目需求要访问系统通讯录获取电话号码，于是乎从一无所知，开始倒腾，倒腾了一下午，总算了弄好了。写这边博客是为了记录一下，自己下一次弄的时候就别在出错了。同时，有和我一样的菜鸟能够避免走一下弯路。
好了，言归正传，要访问系统的通讯录，首先需要添加`AddressBook.framework` 和 `AddressBookUI.framework` 两个框架到你工程中build phase的"Link Binary With Libraries"之下，然后就可以开始了。
首先我们需要创建一个控制器：ViewController，在.h文件中导入头文件：<AddressBook/AddressBook.h>、 <AddressBookUI/AddressBookUI.h>，
~~~
#import <AddressBook/AddressBook.h>
#import <AddressBookUI/AddressBookUI.h>
~~~
然后在控制器实现 ABPeoplePickerNavigationControllerDelegate, UINavigationControllerDelegate协议
~~~
@interface ViewController ()<ABPeoplePickerNavigationControllerDelegate, UINavigationControllerDelegate>
~~~
在viewDidAppear方法中创建ABPeoplePickerNavigationController，同时设置viewController作为委托对象
~~~
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
ABPeoplePickerNavigationController *pNC = [[ABPeoplePickerNavigationController alloc] init];
pNC.peoplePickerDelegate = self;
[self presentViewController:pNC animated:YES completion:nil];
}
~~~
接下来需要实现ABPeoplePickerNavigationControllerDelegate协议
~~~
#pragma mark - ABPeoplePickerNavigationControllerDelegate
- (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker didSelectPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier {
ABMultiValueRef phone = ABRecordCopyValue(person, kABPersonPhoneProperty);
long index = ABMultiValueGetIndexForIdentifier(phone,identifier);
NSString *phoneNO = (__bridge NSString *)ABMultiValueCopyValueAtIndex(phone, index);
phoneNO = [phoneNO stringByReplacingOccurrencesOfString:@"-" withString:@""];
NSLog(@"%@", phoneNO);
if (phone && phoneNO.length == 11) {
[peoplePicker dismissViewControllerAnimated:YES completion:nil];
return;
}else{
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"错误提示" message:@"请选择正确手机号" delegate:self cancelButtonTitle:@"确定" otherButtonTitles:nil];
[alertView show];
}
}
- (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController*)peoplePicker didSelectPerson:(ABRecordRef)person NS_AVAILABLE_IOS(8_0)
{
ABPersonViewController *personViewController = [[ABPersonViewController alloc] init];
personViewController.displayedPerson = person;
[peoplePicker pushViewController:personViewController animated:YES];
}
- (void)peoplePickerNavigationControllerDidCancel:(ABPeoplePickerNavigationController *)peoplePicker
{
[peoplePicker dismissViewControllerAnimated:YES completion:nil];
}
- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person NS_DEPRECATED_IOS(2_0, 8_0)
{
return YES;
}
- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier NS_DEPRECATED_IOS(2_0, 8_0)
{
ABMultiValueRef phone = ABRecordCopyValue(person, kABPersonPhoneProperty);
long index = ABMultiValueGetIndexForIdentifier(phone,identifier);
NSString *phoneNO = (__bridge NSString *)ABMultiValueCopyValueAtIndex(phone, index);
phoneNO = [phoneNO stringByReplacingOccurrencesOfString:@"-" withString:@""];
NSLog(@"%@", phoneNO);
if (phone && phoneNO.length == 11) {
[peoplePicker dismissViewControllerAnimated:YES completion:nil];
return NO;
}else{
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"错误提示" message:@"请选择正确手机号" delegate:self cancelButtonTitle:@"确定" otherButtonTitles:nil];
[alertView show];
}
return YES;
}@end
~~~
到这里本以为大功告成，的确在iOS7是没有任何问题，但是iOS8出现了坑爹的问题，就是选择联系人后
ABPeoplePickerNavigationController会自动dismiss掉，这个问题可坑坏我了。问了谷歌和度娘，在stackvoerflow找到了类似的问题，但是都没有得到解决，在觉得没有办法的时候，又开始看ABPeoplePickerNavigationController.h的头文件，发现了
predicateForSelectionOfPerson属性，于是乎在viewDidAppear方法中加入如下代码：
~~~
if([[UIDevice currentDevice].systemVersion floatValue] >= 8.0){
pNC.predicateForSelectionOfPerson = [NSPredicate predicateWithValue:false];
}
~~~
运行程序，大功告成
iOS开发笔记6：图片轮播及其无限循环效果，ios笔记
最后更新于：2022-04-01 10:06:40
平时APP中的广告位或者滚动的新闻图片等用到的就是图片轮播这种效果，实现方式主要有两种，一种是ScrollView+ImageView，另一种则是通过CollectionView，今天总结的是ScrollView这种方式。
###1.图片轮播效果实现
主要实现思路是：根据图片总数及宽高设置好ScrollView的大小，每切换一张图片相当于在ScrollView上进行一个图片宽度的移动行为，并加入定时器，实现自动轮播。
如图所示，设置好ScrollView及PageControl，ScrollView的contentSize根据图片数量确定，注意启用pagingEnabled这个属性，确保整页移动，同样pageControl也是根据图片数量来确定，每一页代表一张图片。
contentOffset更新页码。
定时器设置，这里设置为每隔2秒滚动更新一次，实际上就是每隔2秒更新一次页码，根据页码的变化，让ScrollView跟着移动，每次移动一张图片的距离
这里还需要注意的是，由于加入定时器有自动轮播的效果了，会与手动拖拽ScrollView冲突，即手动拖拽ScrollView过程时ScrollView可能自动移动更新图片了，显然这种效果是不符合用户习惯的，这时需要在ScrollView的代理事件中进行处理，即开始拖拽ScrollView时停止定时器，拖拽结束后再开启定时器。
那到这里是不是就结束了呢？我们看看效果图：
这里有两个问题：
（1）首先是移动到最后一张图片时无法移动了，如果是制作APP的新特性页面，这样的滚动效果已经可以了，但如果在广告位或者是滚动新闻这些场景下这种效果是不够好的，一般滚动到最后一张图片时，继续拖拽都会移动到第一张图片，实现一种滚动循环效果。
（2）定时器自动轮播图片时，确实图片循环轮播了，但是仔细看会发现，ScrollView是由最后一种图片位置生硬得拉回到第一张图片的位置，效果也不够理想。
解决办法下面接着说。
###2.图片轮播无限循环效果实现
刚刚说到第一个问题，ScrollView移动到最后一张图片时无法移动了，这是因为ScrollView已经移动到最后，而图片又是依次排列，自然也就无法移动。
解决办法是，我们换一个思路实现图片轮播效果，ScrollView上只放三个ImageView，屏幕始终显示中间的ImageView，左边和右边的ImageView分别代表前一张图片和后一张图片，屏幕移动的时候，中间的ImageView变化，同时左右两边的ImageView也随之变化，两种边界情况：
（1）当屏幕显示最后一张图片时，右边的ImageView也即下一站图片应该是最开始的第一张图片；
（2）当屏幕显示最开始的第一张图片时，左边的ImageView也即上一张图片应该是最后一张图片。
这样三个ImageView不断变化就造成一种图片轮播无限循环的效果。 参考：http://www.cnblogs.com/kenshincui/p/3913885.html
相对于之前的效果，有一些改变,主要有：
（1）ScrollView只需要设置三个ImageView即可，并且默认显示中间的ImageView
（2）根据ScrollView的移动情况，迅速变化三个ImageView中图片数据
（3）ImageView更新完毕后，偷偷把ScrollView拉回到中间的ImageView位置，这样视觉效果上就实现了无限循环的效果
效果图：
提高IOS开发效率的工具
最后更新于：2022-04-01 10:06:37
ios开发中又很多可以提高开发效率的工具，这篇文章整理我使用提高效率的工具，如果你也有一些好的工具，可以向我推荐一下。

> 以来管理工具有很多，例如java的maven，android的gradle，js的bower，ios中的cocaPods。他们可以帮你下载第三方包 并管理这些包的依赖关系。
#### 安装
- 1:更新ruby环境 $ gem update rails ＝＝＝＝＝＝＝＝＝ Mac OS X 10.5以上
- 2:更新gem环境 ： gem update --system
- 3:安装cocoapods：sudo gem install cocoapods
- 4:pod setup
#### 配置项目依赖
-
1:创建prdfile文件 :touch Podfile
-
2:输入项目依赖 vi Podfile,例如
~~~
platform :ios, "6.1"
pod 'MBProgressHUD', '~> 0.8'
pod 'MapBox', '~> 1.1.0'
~~~
-
3:pod install 安装
-
4:后续打开项目文件
#### 常用命令
- 1:查看某个库是否存在 －－$ pod search AFNetworking
- 2:更新pod －－$ pod update
- 3：安装pod -- $ pod install
#### 使用下面两条命令可以提高速度，原因是不检查spec仓库更新
- pod install --verbose --no-repo-update
- pod update --verbose --no-repo-update
### 2:xcode好用的插件
> xcode插件可以大大提高开发效率
#### 插件安装方式
- 1：推荐！ 使用Alcatraz安装，commannd + sift + 9 调出图形界面，然后使用搜索插件安装

再打开 MyLib.m 文件， 添加刚刚定义两个文件的实现：
~~~
- (NSInteger) add:(NSInteger)a and:(NSInteger)b {
return a + b;
}
+ (NSString*) connect:(NSString *)str1 and:(NSString *)str2 {
return [NSString stringWithFormat:@"%@ %@", str1, str2];
}
~~~
现在， 最终的文件看起来是这样的：

选中 MyLib 项目， 在中间的编辑器窗口中选择项目的 Target ， 选择 Build Phases 标签， 展开 Copy Headers 分组， 下面有三个子分组， 分别是 Public 、 Project 与 Private ， 将 MyLib.h 拖拽到 Public 分组即可。
保存所有文件， 选择 Product -> Build ， 进行编译， 生成 libMyLib.a 文件， 同时也会将 MyLib.h 文件复制到输出目录。
使用静态类库项目
选择 File -> New -> Project ， 项目模板选择 iOS -> Application -> Single View Application ， 项目名称命名为 MyApp ， 注意勾选 Use Storyboards 和 Use Automatic Reference Counting 。
建好项目之后， 项目窗口如下如所示：
将 MyLib 项目拖拽到 MyApp 项目的 Frameworks 文件夹， 在弹出的对话框中选择 Create groups for any added folders ， 然后点击 Finish 按钮。
选中 MyApp 项目， 在选择项目的目标 (Target) ， 选中 Summary 标签页下找到 Linked Frameworks and Library 分组选项， 如下图：
点击下面的加号按钮， 将工作区的 libMyLib.a 添加进去。
接下来添加头文件搜索目录， 选中 Targets 上面的 Project ， 选择 Build Settings 标签页，在搜索框内输入 header search 进行过滤， 找到 Header Search Paths ， 添加一行， 输入 ../MyLib ， 并选中递归复选框。
现在要先验证一下对 MyLib 的引用是否正确， 打开 MyApp 项目的 ViewController.m ， 添加对 MyLib.h 的引用， 如下图所示， 并编译 MyApp ， 如果编译成功， 则表示引用正确。
打开 MainStoryboard.storyboard 文件， 在生成的 ViewController 上添加两个 UITextField 、 两个 UIButton 以及一个 UILabel， 如下图所示：
并添加相应的 outlet 和 action ， ViewController.h 如下：

百度推送iOS
最后更新于：2022-04-01 10:06:33
1.首先生成CertificateSigningRequest文件。
点击钥匙串访问-->从证书颁发机构请求证书-->填写用户邮件地址-->常用名-->点击储存－－>继续－－>最后点击保存。
在桌面上就可以看见CertificateSigningRequest.certSigningRequest文件就是CSR文件，在我们生成CSR文件的同时，会在钥匙串访问中生成一对秘钥，名称为刚才我们填写的常用名。
2.打开开发者中心 首先创建Identifiers -->在创建Certificates -->在创建Provisoning Profiles
注意：
1.创建Identifiers时，一定要勾选Push Notifications，
2.保证Identifiers中的ID，Certificates中的Name，Provisoning Profiles中的APP ID,应用程序中的Bundle identifier，保持一致。
3.点击钥匙串访问-->我的证书-->找到刚刚生成的.p12文件-->点击导出到桌面。
4.打开中端 -->openssl pkcs12 -in push.p12 -out push.pem -nodes，将.p12文件变成.pem文件。
5.添加到SDK到?工程中的步骤如下:
将 libBPush.a 和 BPush.h 添加到?自?己的?工程下,添加时需要注意勾选当前Target
6.创建并配置BPushConfig.plist文件，在工程中创建一个新的Property List文件，并命名为BPushConfig.plist，添加以下键值：
?
~~~
{
“PRODUCTION_MODE” = NO
“API_KEY” = “uZbmgZKhfumvGYGowcjSPFc1”
“DEBUG” = NO
}
~~~
PRODUCTION_MODE：
必选。应用发布模式。开发证书签名时，值设为”NO”；发布证书签名时，值设为”YES”。请在调试和发布应用时，修改正确设置这个值，以免出现推送通知无法到达。
API_KEY：
必选。百度开发者中心为每个app自动分配的api key，在开发者中心app基本信息中可以查看。
7.SDK需要以下
库: Foundation.framework 、 CoreTelephony.framework 、 libz.dylib 、 SystemConfiguration.framework ,请在?工程中添加
8.在 AppDelegate 中的 application: didFinishLaunchingWithOptions: 中调?用 API,初始化Push:
因为iOS8中对于推送有更改，所以要判断设备的版本
~~~
[BPush setupChannel:launchOptions];
[BPush setDelegate:self]; //参数对象必须实现onMethod: response:方法，
~~~
~~~
#if SUPPORT_IOS8
// 8.0以后使用这种方法来注册推送通知
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0) {
UIUserNotificationType myTypes = UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound;
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:myTypes categories:nil];
[[UIApplication sharedApplication] registerUserNotificationSettings:settings];
}else
#endif
{
UIRemoteNotificationType myTypes = UIRemoteNotificationTypeBadge|UIRemoteNotificationTypeAlert|UIRemoteNotificationTypeSound;
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:myTypes];
}
~~~
9.在application: didRegisterForRemoteNotificationsWithDeviceToken:中调用API，注册device token：
~~~
BPush registerDeviceToken:deviceToken]; // 必须
~~~
[BPush bindChannel]; // 必须。可以在其它时机调用，只有在该方法返回（通过onMethod:response:回调）绑定成功时，app才能接收到Push消息。一个app绑定成功至少一次即可（如果access token变更请重新绑定）。
10.实现BPushDelegate协议，必须实现方法onMethod:response:
~~~
if ([BPushRequestMethod_Bind isEqualToString:method])
{
NSDictionary* res = [[NSDictionary alloc] initWithDictionary:data];
NSString *appid = [res valueForKey:BPushRequestAppIdKey];
NSString *userid = [res valueForKey:BPushRequestUserIdKey];
NSString *channelid = [res valueForKey:BPushRequestChannelIdKey];
int returnCode = [[res valueForKey:BPushRequestErrorCodeKey] intValue];
NSString *requestid = [res valueForKey:BPushRequestRequestIdKey];
}
~~~
11.在application: didReceiveRemoteNotification:中调用API，处理接收到的Push消息：
获取推送后返回的数据
~~~
[BPush handleNotification:userInfo]; // 可选
~~~
将UIview的image保存到本地的方法
最后更新于：2022-04-01 10:06:30
定义一个按钮
点击按钮，将self.imageView上面的image内容保存到本地相册，并指定判断保存成功与否的方法imageSavedToPhotosAlbum:didFinishSavingWithError:contextInfo:
~~~
-(IBAction)saveImageToAlbum:(id)sender {
UIImageWriteToSavedPhotosAlbum(self.imageView.image, self, @selector(imageSavedToPhotosAlbum:didFinishSavingWithError:contextInfo:), nil);
}
~~~
实现imageSavedToPhotosAlbum:didFinishSavingWithError:contextInfo:方法
~~~
- (void)imageSavedToPhotosAlbum:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInfo
{
NSString *message = @"呵呵";
if (!error) {
message = @"成功保存到相册";
}else
{
message = [error description];
}
NSLog(@"message is %@",message);
}
~~~
这些代码很简单，如果没有错误的话就提示“成功保存到相册”，如果保存失败的话，那么就输出错误信息[error description]。
UIbutton文字相关
最后更新于：2022-04-01 10:06:28
## UIButton 文字显示位置设置 字体的大小设置 字体的颜色设置 注意事项
~~~
btn.frame = CGRectMake(x, y, width, height);
[btn setTitle: @"search" forState: UIControlStateNormal];
//设置按钮上的自体的大小
//[btn setFont: [UIFont systemFontSize: 14.0]]; //这种可以用来设置字体的大小，但是可能会在将来的SDK版本中去除改方法
//应该使用
btn.titleLabel.font = [UIFont systemFontOfSize: 14.0];
[btn seBackgroundColor: [UIColor blueColor]];
//最后将按钮加入到指定视图superView
[superView addSubview: btn];
~~~
==========================================================
~~~
tvnamelabel=[[UIButton alloc]initWithFrame:CGRectMake(5,5,200,40)];
~~~
这样初始化的button，文字默认颜色是白色的，所有如果背景也是白色的话，是看不到文字的，
~~~
btn.contentHorizontalAlignment=UIControlContentHorizontalAlignmentLeft ;//设置文字位置，现设为居左，默认的是居中
[btn setTitle:@“title”forState:UIControlStateNormal];// 添加文字
~~~
有些时候我们想让UIButton的title居左对齐，我们设置
~~~
btn.textLabel.textAlignment = UITextAlignmentLeft
~~~
是没有作用的，我们需要设置
~~~
btn.contentHorizontalAlignment = UIControlContentHorizonAlignmentLeft;
~~~
但是问题又出来，此时文字会紧贴到做边框，我们可以设置
~~~
btn.contentEdgeInsets = UIEdgeInsetsMake(0,10, 0, 0);
~~~
使文字距离做边框保持10个像素的距离。
=======================================================
设置UIButton上字体的颜色设置UIButton上字体的颜色，不是用：
~~~
[btn.titleLabel setTextColor:[UIColorblackColor]];
btn.titleLabel.textColor=[UIColor redColor];
~~~
而是用：
~~~
[btn setTitleColor:[UIColor blackColor]forState:UIControlStateNormal];

上传APP至AppStore时打包出现U option must have a non-empty value
最后更新于：2022-04-01 10:06:26
今天升级APP时要用application loader上传到AppStore上去，打包之后上传的时候报错，用的是Xcode7.0，如下：
1.the u option must have a non-empty value
2.the password must have a non-empty value
后来查了一下，有两个解决办法：
1：去iTunes connect下一个application loader3.1的dmg
2：就是把你的Xcode7.0升级到7.1的版本，7.1附带的application loader是3.3的
iOS开发中@2x等后缀的图片干嘛用的
最后更新于：2022-04-01 10:06:24
开发中，例如：
nanshanImage.image=[UIImage imageNamed:@"index_pic.png"];
在项目中还保存中index_pic@2x.png的图片，此图为了只适应960*640的分辨率手机
而index_pic.png是适应640*320的手机，但是在代码中必须写成[UIImage imageNamed:@"index_pic.png"];这样系统自动会根据不同分辨率手机决定是否调用index_pic@2x.png还是index_pic.png，会自动根据分辨率来匹配用哪张图。
可是如果写成[UIImage imageNamed:@"index_pic@2x.png"];那么系统无法自动判断，根据640*320分辨率来调用index_pic.png图片，系统只会将index_pic@2x.png这一张图当做某控件的图片，不会自动寻找匹配。
因此，开发中[UIImage imageNamed:@"index_pic.png"];里面的图片都是用小分辨率格式名的图片，这样会自动适应大分辨率图片，直接调用。
注意：xib中选择图片做背景时，也是一样的原理！也是选择不带@2x的，这样会自带根据分辨率匹配是否使用小图还是@2x大图！
