iPad上的新iOS 7 UIActionSheet在有大量按钮时无法正确显示。
在滚动时未清除UIActionSheet的背景。按钮似乎被冻结在背景UIActionSheet中。
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];
