带有许多按钮的Xcode iPad UIActionSheet无法正确显示iOS7 [英] Xcode iPad UIActionSheet with many buttons do not correctly displayed iOS7

问题描述

在iPad上，新的ios 7 UIActionSheet没有正确显示，有很多按钮。

On the iPad new ios 7 UIActionSheet is not correctly displayed with lots of buttons.

在滚动时不清除UIActionSheet的背景。按钮似乎在背景UIActionSheet中冻结。

Not cleaning background of UIActionSheet on scrolling. The buttons seem frozen in background UIActionSheet.

问题

我的代码：

UIActionSheet *popupQuery = [[UIActionSheet alloc]; 
for (int i=0; i<[ParamAllList count]; i++) 
{ 
    NSMutableDictionary *Param = [ParamAllList objectAtIndex:i]; 
    [popupQuery addButtonWithTitle:[Param valueForKey:@"name"]]; 
    [[[popupQuery valueForKey:@"_buttons"] objectAtIndex:[[popupQuery valueForKey:@"_buttons"] count]-1] setImage:[UIImage imageNamed:@"add40icon.png"] forState:UIControlStateNormal];
} 
popupQuery.actionSheetStyle = UIActionSheetStyleAutomatic; 
[popupQuery showFromRect:Button_Settings.frame inView:Button_Settings.superview animated:YES];

推荐答案

这是我对actionSheet委托的解决方法：

This was my workaround for the actionSheet delegate:

- (void)willPresentActionSheet:(UIActionSheet *)actionSheet {
    actionSheet.backgroundColor = [UIColor whiteColor];
    for (UIView *subview in actionSheet.subviews) {
        subview.backgroundColor = [UIColor whiteColor];
    }
}
