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){ //4，4SlaunchImageName = @"LaunchImage-700";}else if (screenHeight == 568){ //5, 5C, 5S, iPodlaunchImageName = @"LaunchImage-700-568h";}else if (screenHeight == 667){ //6, 6SlaunchImageName = @"LaunchImage-800-667h";}else if (screenHeight == 736){ // 6Plus, 6SPluslaunchImageName = @"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); /* 打印日志： {  BuildMachineOSBuild = 15G31;  CFBundleDevelopmentRegion = en;  CFBundleExecutable = TanTest;  CFBundleIcons = {  CFBundlePrimaryIcon =  {   CFBundleIconFiles =  (   AppIcon29x29,   AppIcon40x40,   AppIcon60x60   );  };  };  CFBundleIdentifier = "net.tan.xxx";  CFBundleInfoDictionaryVersion = "6.0";  CFBundleInfoPlistURL = "Info.plist -- file:///Users/PX/Library/Developer/CoreSimulator/Devices/7020368B-C160-42C0-B3C5-5F958FA82EF5/data/Containers/Bundle/Application/77D8C333-A6AF-4183-B79A-A5BEDCD08E1A/TanTest.app/";  CFBundleName = TanTest;  CFBundleNumericVersion = 16809984;  CFBundlePackageType = APPL;  CFBundleShortVersionString = "1.0";  CFBundleSignature = "????";  CFBundleSupportedPlatforms = (  iPhoneSimulator  );  CFBundleVersion = 1;  DTCompiler = "com.apple.compilers.llvm.clang.1_0";  DTPlatformBuild = "";  DTPlatformName = iphonesimulator;  DTPlatformVersion = "9.3";  DTSDKBuild = 13E230;  DTSDKName = "iphonesimulator9.3";  DTXcode = 0731;  DTXcodeBuild = 7D1014;  LSRequiresIPhoneOS = 1;  MinimumOSVersion = "6.0";  UIDeviceFamily = (  );  UILaunchImageFile = LaunchImage;  UILaunchImages = (  {   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}";  }  );  UILaunchStoryboardName = LaunchScreen;  UIMainStoryboardFile = Main;  UIRequiredDeviceCapabilities = (  armv7  );  UISupportedInterfaceOrientations = (  UIInterfaceOrientationPortrait  ); } */}

---------- 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

/** 打印app工程配置信息 */- (void)printInfoDictionary{ NSDictionary *infoDict = [[NSBundle mainBundle] infoDictionary]; NSLog(@"%@", infoDict); /* 打印日志： { BuildMachineOSBuild = 15G31; CFBundleDevelopmentRegion = en; CFBundleExecutable = TanTest; CFBundleIcons = {  CFBundlePrimaryIcon =  {  CFBundleIconFiles =  (       AppIcon29x29,       AppIcon40x40,       AppIcon60x60,       AppIcon76x76,       "AppIcon83.5x83.5"       );  }; }; CFBundleIdentifier = "net.tan.xxx"; CFBundleInfoDictionaryVersion = "6.0"; CFBundleInfoPlistURL = "Info.plist -- file:///Users/PX/Library/Developer/CoreSimulator/Devices/3246F9AE-1D73-4E4F-8DDF-F591DBE64F63/data/Containers/Bundle/Application/7DD6C793-F882-43CF-9897-1433411289E6/TanTest.app/"; CFBundleName = TanTest; CFBundleNumericVersion = 16809984; CFBundlePackageType = APPL; CFBundleShortVersionString = "1.0"; CFBundleSignature = "????"; CFBundleSupportedPlatforms = (      iPhoneSimulator      ); CFBundleVersion = 1; DTCompiler = "com.apple.compilers.llvm.clang.1_0"; DTPlatformBuild = ""; DTPlatformName = iphonesimulator; DTPlatformVersion = "9.3"; DTSDKBuild = 13E230; DTSDKName = "iphonesimulator9.3"; DTXcode = 0731; DTXcodeBuild = 7D1014; LSRequiresIPhoneOS = 1; MinimumOSVersion = "9.0"; UIDeviceFamily = (    1,    ); UILaunchImageFile = LaunchImage; UILaunchImages = (    {     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}";    }    ); UILaunchStoryboardName = LaunchScreen; UIMainStoryboardFile = Main; UIRequiredDeviceCapabilities = (      armv7      ); UISupportedInterfaceOrientations = (      UIInterfaceOrientationPortrait,      UIInterfaceOrientationLandscapeLeft,      UIInterfaceOrientationLandscapeRight      ); }*/}
