UIImageView stopAnimation無法在viewDidLoad上運行？

Question

我正在嘗試在viewDidAppear階段啟動imageView的動畫。

當webview的內容加載到viewDidLoaded階段時，我想停止動畫。

但是，當調用stopAnimation時，我的UIImageView不會停止動畫

在ViewDidLoaded階段。

誰能告訴我該怎么做才能停止viewDidLoaded上的動畫？

任何幫助將不勝感激。

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  
}

Answer 1

使用UIWebViewDelegate和協議方法webViewDidFinishLoad

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

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

}
