UIView中如何居中一个label

请问有没有什么好办法能够在UIView中居中一个label.如果你用下面代码UILabel *myLabel = [[UILabel alloc] initWithFrame:CGRectMake(view.frame.origin.x / 2, view.frame.origin.y / 2, 50.0, 50.0)]; 然后你要设置label的起点位置为视图的中央。我尝试修改属性去完成。UIView *aView = [[[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]] autorelease];aView.backgroundColor = [UIColor darkGrayColor];CGRect frame = aView.frame;UILabel *aLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 125.0f, 30.0f)];[aLabel setCenter:CGPointMake(frame.origin.x / 2, frame.origin.y / 2)];但是结果还是不行

UIView *aView = [[[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]] autorelease];aView.backgroundColor = [UIColor darkGrayColor];UILabel *aLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 125, 30)];aLabel.center = aView.center;
