Question

MBProgressView無法在UICollectionView上等待iOS 它在其他視圖控制器中工作正常，但是當我在uicollection視圖控制器中使用時，它不在屏幕上顯示，請給我一個解決方案。

UICollectionVIEW Code

Answer 1

嘗試加入上海華：

[MBProgressHUD showHUDAddedTo:self.collectionView.superview animated:YES]; 

UPDATE

好吧，我檢查你的代碼，這有點搞砸了。所以

- (void)viewDidDisappear:(BOOL)animated { 
    NSLog(@"viewDidDisappear in Main Page"); 
    // Looks like you want to hide your HUD here. 
    // This code will be called right after [self.tabBarController setSelectedIndex:1], 
    // cause current with gonna disappear. 
    [MBProgressHUD hideHUDForView:self.view animated:YES]; 
} 

，如果你真的希望看到HUD（目前還不清楚它應該是多久可見）： 這裏發生：

- (void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath 
{ 
    if (indexPath.row == 0) { 

     // You about to show HUD in your current VC views hierarchy 
     MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.collectionView.superview animated:YES]; 
     hud.labelText = @"Loading..."; 
     // But immediately switching to another. Current VC will be off screen. 
     // You will not see your HUD 
     [self.tabBarController setSelectedIndex:1]; 
    } 
... 

然後

- (void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath 
{ 
    if (indexPath.row == 0) { 
     MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.tabBarController.view]; 
    // hide after 4 seconds 
    [hud hide:YES afterDelay:4]; 

...
