UIday0603:UIImageView的属性和用法 Tom猫举例

UIImageView常⽤用属性

image //设置图⽚

animationImages //设置⼀组动态图片

animationDuration //设置播放一次一组动态图片的时间

animationRepeatCount //设置重复次数

startAnimating //开始动画

stopAnimating //结束动画

UIImageView相当于一个相框，可以存放一个或一组图片 UIImage 是图片对象

AppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.

self.window.rootViewController = rootVC;

return YES;
}
