-[UIPickerView setFrame:]:无效的高度值 200.0 固定到 180.0 我在 nslog 中收到此错误。但我不在乎。未来有可能发生任何崩溃吗?. 我的编码是
pickerviewdropdown.Dropoption = [[Utility getSizeValues] mutableCopy];
[pickerviewdropdown.pickerview reloadAllComponents];
subOptionPopOver = [[UIPopoverController alloc] initWithContentViewController:pickerviewdropdown];
[subOptionPopOver setPopoverContentSize:CGSizeMake(200, 200)];
[subOptionPopOver presentPopoverFromRect:[sender bounds]
inView:sender
permittedArrowDirections:UIPopoverArrowDirectionAny
animated:NO];
