在iPad上,新的ios 7 UIActionSheet没有正确显示许多按钮.
不清理UIActionSheet的滚动背景.这些按钮似乎在背景UIActionSheet中冻结.
screenshot with problem
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];
解决方法
这是我的actionSheet代理的解决方法：
- (void)willPresentActionSheet:(UIActionSheet *)actionSheet {
actionSheet.backgroundColor = [UIColor whiteColor];
for (UIView *subview in actionSheet.subviews) {
subview.backgroundColor = [UIColor whiteColor];
}
}
