iOS获取app图标和启动图片名字（AppIcon and LaunchImage's name）
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 == ){ //4，4S
launchImageName = @"LaunchImage-700";
}
else if (screenHeight == ){ //5, 5C, 5S, iPod
launchImageName = @"LaunchImage-700-568h";
}
else if (screenHeight == ){ //6, 6S
launchImageName = @"LaunchImage-800-667h";
}
else if (screenHeight == ){ // 6Plus, 6SPlus
launchImageName = @"LaunchImage-800-Portrait-736h";
} if (launchImageName.length < ) 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 == ) || (isLandscape && screenWidth == )){
launchImageName = @"LaunchImage-700";
}
//5、5C、5S、iPod 竖屏，横屏
else if ((isPortrait && screenHeight == ) || (isLandscape && screenWidth == )){
launchImageName = @"LaunchImage-700-568h";
}
//6、6S 竖屏，横屏
else if ((isPortrait && screenHeight == ) || (isLandscape && screenWidth == )){
launchImageName = @"LaunchImage-800-667h";
}
//6Plus、6SPlus竖屏
else if (isPortrait && screenHeight == ){
launchImageName = @"LaunchImage-800-Portrait-736h";
}
//6Plus、6SPlus 横屏
else if (isLandscape && screenWidth == ){
launchImageName = @"LaunchImage-800-Landscape-736h";
}
//iPad 竖屏
else if (isPortrait && screenHeight == ){
launchImageName = @"LaunchImage-700-Portrait";
}
//iPad 横屏
else if (isLandscape && screenWidth == ){
launchImageName = @"LaunchImage-700-Landscape";
} if (launchImageName.length < ) 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);
/*
