應用程序崩潰說集合表達式類型的UIView * countByEnumeratingWithState」可能不響應「：對象：伯爵「」

Question

我有一個UIImageView一個的tableView內，要在單擊行時以編程方式刪除它

-(void) tableView:(UITableView *) tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath 
    { 

      for (UIView *subview in tableView) 
      { 
       if([subview isKindOfClass:[UIImageView class]]) 
       { 
       [subview removeFromSuperview]; 
       } 
      } 
} 

當我點擊應用程序崩潰的錶行。Warning : Collection expression type UIView* may not respond to countByEnumeratingWithState:object:count" 同一封郵件遞交該應用程序崩潰。我在這裏錯過了什麼？我只粘貼代碼的相關部分。

Answer 1

代碼應該像

for (UIView *subview in tableView.subviews) 

Answer 2

改變循環到下面的代碼

for (UIView *subview in [tableView subviews]) 
    { 
     if([subview isKindOfClass:[UIImageView class]]) 
     { 
      [subview removeFromSuperview]; 
     } 
    } 

Answer 3

嘗試。它可以幫助你..

-(void) tableView:(UITableView *) tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
     NSArray *cells = [tableView visibleCells]; 
     UITableViewCell *currentCell = nil; 
     for (UITableViewCell *cell in cells) 
     { 
      NSIndexPath *currentIndexPath = [tableView indexPathForCell:cell]; 
      if(currentIndexPath.row == indexPath.row && currentIndexPath.section == indexPath.section) 
      { 
       currentCell = cell; 
       break; 
      } 
     } 
    for(UIView *subView in [[currentCell contentView] subviews]) 
    { 
     // do your stuff. 
    } 

}
