無法從視圖中刪除子視圖？

我想從UIView中刪除指標子視圖，但它刪除了它們而不僅僅是子視圖。無法從視圖中刪除子視圖？

我的看法是：

UIView * aView = [[UIView alloc] initWithFrame:CGRectMake(0.5*winSize.width-winSize.width/3, 0.85*winSize.height , winSize.width/1.5, winSize.width/8)]; 
    aView.backgroundColor = [UIColor clearColor]; 
    aView.tag = 31000; 
    UIActivityIndicatorView *av = [[[UIActivityIndicatorView alloc]initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhite] autorelease]; 
    av.frame=aView.bounds; 
    [av setBackgroundColor:[UIColor colorWithRed:0.23 green:0.23 blue:0.23 alpha:0.85]]; 
    av.layer.cornerRadius=4; 
    av.tag = 31001; 
    [aView addSubview:av]; 
    [[[CCDirector sharedDirector]view]addSubview:aView]; 
    [av startAnimating];

，我已經嘗試了許多方法去除它，我已經在這裏找到：

UIActivityIndicatorView *tmpimg = (UIActivityIndicatorView *)[[[CCDirector sharedDirector]view] viewWithTag:31001]; 
    if(tmpimg) 
     [((UIView *)tmpimg) removeFromSuperview];

或

UIView *removeView; 
    while((removeView = [[[CCDirector sharedDirector]view] viewWithTag:31001]) != nil) 
    { 
     [removeView removeFromSuperview]; 
    }

或

UIView * aView = [[[CCDirector sharedDirector]view] viewWithTag:31000]; 
    if(aView) 
     for(UIView *subview in [aView subviews]) 
      [subview removeFromSuperview];

，但它始終刪除他們兩個......我失去了..

你在調用之前和之後添加子視圖的日誌，並確保刪除活動指示符也會導致超級視圖被刪除？ – Wain 2013-04-24 11:28:03

oops。我很愚蠢。第一個插入清晰的顏色，它仍然存在..... – Curnelious 2013-04-24 11:29:35

你有解決方案嗎？ – yen 2013-04-24 11:33:57

這會從您的視圖中刪除任何UIActivityIndicatorView，無需任何標記就什麼是國際海事組織一個壞的解決方案

for (UIView *aSubView in aView) { 
    if ([aSubView isKindOfClass:[UIActivityIndicatorView class]]) 
     [aSubView removeFromSuperview]; 
}
