iOS获取AppIcon and LaunchImage's name(app图标和启动图片名字)

在某种场景下，可能我们需要获取app的图标名称和启动图片的名称。比如说app在前台时，收到了远程通知但是通知栏是不会有通知提醒的，这时我想做个模拟通知提示，需要用到icon名称；再比如在加载某个控制器时，想设置该控制器的背景图片为启动图片，需要用到启动图片名称。

　　而事实上icon图片放在系统AppIcon文件夹里，启动图片放在系统LaunchImage文件夹里，取这些图片的名称和其他一般资源图片名称不一样。

　　为了方便举例子，咱们先简单粗暴点

假设当前项目只支持iPhone设备，并且只支持竖屏；而且当前项目里已经设置好了AppIcon图标和启动图片，

如何获取icon图标名称和启动图片名称呢 ？

上代码和打印日志：

/** 获取app的icon图标名称 */
- (void)getAppIconName{
NSDictionary *infoDict = [[NSBundle mainBundle] infoDictionary];
//获取app中所有icon名字数组
NSArray *iconsArr = infoDict[@"CFBundleIcons"][@"CFBundlePrimaryIcon"][@"CFBundleIconFiles"];
//取最后一个icon的名字
NSString *iconLastName = [iconsArr lastObject];
//打印icon名字
NSLog(@"iconsArr: %@", iconsArr);
NSLog(@"iconLastName: %@", iconLastName);
/*
打印日志：
iconsArr: (
AppIcon29x29,
AppIcon40x40,
AppIcon60x60
)
iconLastName: AppIcon60x60
*/
}
/** 获取app的启动图片名称，并设置为本控制器背景图片 */
- (void)getLaunchImageName{
NSString *launchImageName = @""; //启动图片名称变量
CGFloat screenHeight = [UIScreen mainScreen].bounds.size.height;
//获取与当前设备匹配的启动图片名称
if (screenHeight == 480){ //4，4S
launchImageName = @"LaunchImage-700";
}
else if (screenHeight == 568){ //5, 5C, 5S, iPod
launchImageName = @"LaunchImage-700-568h";
}
else if (screenHeight == 667){ //6, 6S
launchImageName = @"LaunchImage-800-667h";
}
else if (screenHeight == 736){ // 6Plus, 6SPlus
launchImageName = @"LaunchImage-800-Landscape-736h";
}
if (launchImageName.length < 1) return;
//设备启动图片为控制器的背景图片
UIImage *img = [UIImage imageNamed:launchImageName];
self.view.backgroundColor = [UIColor colorWithPatternImage:img];
}

打印当前只支持iPhone设备并且只支持竖屏场景下的所有启动图片信息：

/** 打印app里面所有启动图片名称信息 */
- (void)printAllLaunchImageInfo{
 NSDictionary *infoDict = [[NSBundle mainBundle] infoDictionary];
 //获取所有启动图片信息数组
 NSArray *launchImagesArr = infoDict[@"UILaunchImages"];
 NSLog(@"launchImagesArr: %@", launchImagesArr);
 /*
 打印日志：启动图片的名字是固定的
 launchImagesArr: (
  {
  UILaunchImageMinimumOSVersion = "8.0";
  UILaunchImageName = "LaunchImage-800-Portrait-736h";
  UILaunchImageOrientation = Portrait;
  UILaunchImageSize = "{414, 736}";
  },
  {
  UILaunchImageMinimumOSVersion = "8.0";
  UILaunchImageName = "LaunchImage-800-Landscape-736h";
  UILaunchImageOrientation = Landscape;
  UILaunchImageSize = "{414, 736}";
  },
  {
  UILaunchImageMinimumOSVersion = "8.0";
  UILaunchImageName = "LaunchImage-800-667h";
  UILaunchImageOrientation = Portrait;
  UILaunchImageSize = "{375, 667}";
  },
  {
  UILaunchImageMinimumOSVersion = "7.0";
  UILaunchImageName = "LaunchImage-700";
  UILaunchImageOrientation = Portrait;
  UILaunchImageSize = "{320, 480}";
  },
  {
  UILaunchImageMinimumOSVersion = "7.0";
  UILaunchImageName = "LaunchImage-700-568h";
  UILaunchImageOrientation = Portrait;
  UILaunchImageSize = "{320, 568}";
  }
 )
 */
}

看到了，项目AppIcon图标和启动图片信息，都可以从 [[NSBundle mainBundle] infoDictionary] 获得，当前这里面还包含了app的其他信息如版本、app名称、设备类型、支持方向。。。

打印所有信息看看：

/** 打印app工程配置信息 */
- (void)printInfoDictionary{
 NSDictionary *infoDict = [[NSBundle mainBundle] infoDictionary];
 NSLog(@"%@", infoDict);
 /*

 */
}

---------- 接下来我们再来在app既支持iPhone和iPad设备，又支持横屏和竖屏时，AppIcon和LaunchImage是怎样的以及如何获取 ---

先上两张图，再上测试代码：

测试代码：

1、获取AppIcon所有icon图标名称

/** 支持iPhone和iPad， 获取app的icon图标名称 */
- (void)getAppIconName{
 NSDictionary *infoDict = [[NSBundle mainBundle] infoDictionary];
 //获取app中所有icon名字数组
 NSArray *iconsArr = infoDict[@"CFBundleIcons"][@"CFBundlePrimaryIcon"][@"CFBundleIconFiles"];
 //取最后一个icon的名字
 NSString *iconLastName = [iconsArr lastObject];
 //打印icon名字
 NSLog(@"iconsArr: %@", iconsArr);
 NSLog(@"iconLastName: %@", iconLastName);
 /*
 打印日志(29pt和40pt iPhone和iPad都用到；60pt --- iPhone, 76pt和83.5pt --- iPad)：
 iconsArr: (
  AppIcon29x29,
  AppIcon40x40,
  AppIcon60x60,
  AppIcon76x76,
  "AppIcon83.5x83.5"
 )
 iconLastName: AppIcon83.5x83.5
 */
}

2、获取在支持iPhone和iPad开发，支持横屏和竖屏时，获取启动图片，并设为背景图片代码

(iPhone设备只有在Plus, 即5.5英寸才有竖屏和横屏两套图片，其他4、5、6竖屏横屏共用一张启动图片)

/**
 支持iPhone和iPad, 支持横屏、竖屏，
 获取app的启动图片名称，并设置为本控制器背景图片
 */
- (void)getLaunchImageName{
 NSString *launchImageName = @""; //启动图片名称变量
 CGFloat screenHeight = [UIScreen mainScreen].bounds.size.height; //屏幕高度
 CGFloat screenWidth = [UIScreen mainScreen].bounds.size.width; //屏幕宽度
 //设备界面方向
 UIInterfaceOrientation orientation = [UIApplication sharedApplication].statusBarOrientation;
 BOOL isPortrait = UIInterfaceOrientationIsPortrait(orientation);// 是否竖屏
 BOOL isLandscape = UIInterfaceOrientationIsLandscape(orientation);//是否横屏
 //获取与当前设备匹配的启动图片名称
 //4、4S 竖屏，横屏
 if ((isPortrait && screenHeight == 480) || (isLandscape && screenWidth == 480)){
 launchImageName = @"LaunchImage-700";
 }
 //5、5C、5S、iPod 竖屏，横屏
 else if ((isPortrait && screenHeight == 568) || (isLandscape && screenWidth == 568)){
 launchImageName = @"LaunchImage-700-568h";
 }
 //6、6S 竖屏，横屏
 else if ((isPortrait && screenHeight == 667) || (isLandscape && screenWidth == 667)){
 launchImageName = @"LaunchImage-800-667h";
 }
 //6Plus、6SPlus竖屏
 else if (isPortrait && screenHeight == 736){
 launchImageName = @"LaunchImage-800-Portrait-736h";
 }
 //6Plus、6SPlus 横屏
 else if (isLandscape && screenWidth == 736){
 launchImageName = @"LaunchImage-800-Landscape-736h";
 }
 //iPad 竖屏
 else if (isPortrait && screenHeight == 1024){
 launchImageName = @"LaunchImage-700-Portrait";
 }
 //iPad 横屏
 else if (isLandscape && screenWidth == 1024){
 launchImageName = @"LaunchImage-700-Landscape";
 }
 if (launchImageName.length < 1) return;
 //设备启动图片为控制器的背景图片
 UIImage *img = [UIImage imageNamed:launchImageName];
 self.view.backgroundColor = [UIColor colorWithPatternImage:img];
}

3、打印出所有启动图片信息

/** 打印app里面所有启动图片名称信息 */
- (void)printAllLaunchImageInfo{
 NSDictionary *infoDict = [[NSBundle mainBundle] infoDictionary];
 //获取所有启动图片信息数组
 NSArray *launchImagesArr = infoDict[@"UILaunchImages"];
 NSLog(@"launchImagesArr: %@", launchImagesArr);
 /*
 打印日志：启动图片的名字是固定的
 launchImagesArr: (
  {
  UILaunchImageMinimumOSVersion = "8.0";
  UILaunchImageName = "LaunchImage-800-Portrait-736h";
  UILaunchImageOrientation = Portrait;
  UILaunchImageSize = "{414, 736}";
  },
  {
  UILaunchImageMinimumOSVersion = "8.0";
  UILaunchImageName = "LaunchImage-800-Landscape-736h";
  UILaunchImageOrientation = Landscape;
  UILaunchImageSize = "{414, 736}";
  },
  {
  UILaunchImageMinimumOSVersion = "8.0";
  UILaunchImageName = "LaunchImage-800-667h";
  UILaunchImageOrientation = Portrait;
  UILaunchImageSize = "{375, 667}";
  },
  {
  UILaunchImageMinimumOSVersion = "7.0";
  UILaunchImageName = "LaunchImage-700";
  UILaunchImageOrientation = Portrait;
  UILaunchImageSize = "{320, 480}";
  },
  {
  UILaunchImageMinimumOSVersion = "7.0";
  UILaunchImageName = "LaunchImage-700-568h";
  UILaunchImageOrientation = Portrait;
  UILaunchImageSize = "{320, 568}";
  },
  {
  UILaunchImageMinimumOSVersion = "7.0";
  UILaunchImageName = "LaunchImage-700-Portrait";
  UILaunchImageOrientation = Portrait;
  UILaunchImageSize = "{768, 1024}";
  },
  {
  UILaunchImageMinimumOSVersion = "7.0";
  UILaunchImageName = "LaunchImage-700-Landscape";
  UILaunchImageOrientation = Landscape;
  UILaunchImageSize = "{768, 1024}";
  }
 )
 */
}

4、打印所有配置信息
