获取APP的图标和启动图

获取APP的图标和启动图

公司的app又新的需求，在某些地方会用到app的图标和启动图，但是图标和启动图放在系统的文件夹里，获取这些图标的方式和一般加载资源的方式不一样。

获取图标

NSDictionary *APPInfo = [[NSBundle mainBundle] infoDictionary];    
NSArray *appIcons = APPInfo[@"CFBundleIcons"][@"CFBundlePrimaryIcon"][@"CFBundleIconFiles"];
UIImage *icon = appIcons.lastObject;

获取启动图

NSDictionary *infoDict = [[NSBundle mainBundle] infoDictionary];
NSArray *launchImageArr = infoDict[@"UILaunchImages"];
// 这个数组中就是启动
// 可以根据屏幕的高度获取对应的图片

UILaunchImages =     (
                {
            UILaunchImageMinimumOSVersion = "12.0";
            UILaunchImageName = "LaunchImage-1200-Portrait-2688h";
            UILaunchImageOrientation = Portrait;
            UILaunchImageSize = "{414, 896}";
        },
                {
            UILaunchImageMinimumOSVersion = "12.0";
            UILaunchImageName = "LaunchImage-1200-Portrait-1792h";
            UILaunchImageOrientation = Portrait;
            UILaunchImageSize = "{414, 896}";
        },
                {
            UILaunchImageMinimumOSVersion = "11.0";
            UILaunchImageName = "LaunchImage-1100-Portrait-2436h";
            UILaunchImageOrientation = Portrait;
            UILaunchImageSize = "{375, 812}";
        },
                {
            UILaunchImageMinimumOSVersion = "8.0";
            UILaunchImageName = "LaunchImage-800-Portrait-736h";
            UILaunchImageOrientation = Portrait;
            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}";
        }
    );

获取app的其他信息

如果需要获取app的名字版本号等等都可以从info的字典中获取，具体的对应的key可以打印出来
