MBProgressHUD UIWebView

Question

MBProgressHUD出了点小问题。我有一个网页视图，并希望在数据加载时显示HUD。HUD出现了，但只停留了几秒钟，并且已经消失了，但是webview并没有完成加载。

-(void)viewDidAppear:(BOOL)animated{

// Should be initialized with the windows frame so the HUD disables all user input by covering the entire screen
HUD = [[MBProgressHUD alloc] initWithWindow:[UIApplication sharedApplication].keyWindow];

// Add HUD to screen
[self.view.window addSubview:HUD];

// Regisete for HUD callbacks so we can remove it from the window at the right time
HUD.delegate = self;

HUD.labelText = @"Loading";
HUD.detailsLabelText = @"updating data";

// Show the HUD while the provided method executes in a new thread
[HUD showWhileExecuting:@selector(loadingWebView) onTarget:self withObject:nil animated:YES];}

- (void) loadingWebView {

NSString *fullURL = beverageViewString; 
NSURL *url = [NSURL URLWithString:fullURL]; 
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url]; 
[beverageView loadRequest:requestObj];
NSLog(@"%@",beverageViewString);}

Answer 1

删除showWhileExecuting方法并将hud隐藏在UIWebView的下面的委托方法中，然后它就可以正常工作了

- (void)webViewDidFinishLoad:(UIWebView *)webView
{
    [HUD hide:YES];
}

Answer 2

我们从未将web视图与MBProgressView HUD集成在一起，而不是使用这个，您应该在这里使用UIActivityIndicator，并在webView的这个代理处停止& resignFromSuperView：

• (void)webViewDidFinishLoad:(UIWebView *)webView

您可以在此代理中手动隐藏HUD：

 - (void)webViewDidFinishLoad:(UIWebView *)webView
{
   [HUD hide:YES];
   if(HUD!=nil)
   { 
       [HUD removeFromSuperview];
       [HUD release];
       HUD=nil;
   }
}
