Question

我正在尝试在viewDidAppear阶段启动imageView的动画。

我希望在viewDidLoaded阶段加载webview的内容时停止动画。

然而，当调用stopAnimation时，我的UIImageView不会停止动画

在ViewDidLoaded阶段。

任何人都可以告诉我如何在viewDidLoaded上停止动画？

任何帮助将不胜感激。

UIImageView *customActivityIndicator;

-(void)viewDidAppear:(BOOL)animated{ 
    ...

    customActivityIndicator = [[UIImageView alloc] initWithFrame:CGRectMake(loadingPosX, loadingPosY, loadingImageWidth, loadingImageHeight)]; 
    [self.view addSubview: customActivityIndicator]; 
    customActivityIndicator.animationImages = [NSArray arrayWithObjects:[UIImage imageNamed:@"1.png"],[UIImage imageNamed:@"2"],[UIImage imageNamed:@"3.png"],[UIImage imageNamed:@"4.png"],[UIImage imageNamed:@"5.png"],nil]; 
    customActivityIndicator.animationDuration = 1.0; // in seconds 
    customActivityIndicator.animationRepeatCount = 0; // sets to loop 
    [customActivityIndicator startAnimating]; // starts animating 
} 

- (void)viewDidLoad { 
    [super viewDidLoad];
    ....
    [webView loadRequest : requestObj];
    [customActivityIndicator stopAnimating]; // stop animating  
}

使用 UIWebViewDelegate 和协议方法 webViewDidFinishLoad

- (void)webViewDidFinishLoad:(UIWebView *)webView
 {
    [customActivityIndicator stopAnimating]; // stop animating  
 }

- (void)viewDidLoad { 
    [super viewDidLoad];
    ....
    webView.delegate = self;
    [webView loadRequest : requestObj];

}

UIImageView stopAnimation无法在viewDidLoad上运行？
