ios - 如何以编程方式设置 UIButton 的垂直对齐方式 - iOS

Question

我知道如何使用 IB 设置按钮的垂直对齐方式；见here .但我不能以编程方式做到这一点......这是我尝试过的事情之一:

UIButton *button  = [[UIButton alloc] initWithFrame:CGRectMake(10, 10, 110, 130)];
[button setTitle:@"Align" forState:UIControlStateNormal];
button.backgroundColor = [UIColor whiteColor];
button.titleLabel.textColor = [UIColor grayColor];
[button setContentVerticalAlignment:UIControlContentVerticalAlignmentBottom];

[self.view addSubview:button];

[button release];

我也试过插入...

但是对齐不会改变。

请注意，我想保留按钮的 CustomStyle(我不想要默认的外观和感觉)。

您可以通过这种方式对齐(水平和垂直)按钮的文本:

        UIButton *button  = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 200, 70)];
        button.backgroundColor = [UIColor whiteColor];
        button.contentHorizontalAlignment = UIControlContentHorizontalAlignmentLeft;
        button.contentVerticalAlignment = UIControlContentVerticalAlignmentBottom;
        [button setTitle:@"Align" forState:UIControlStateNormal];
        [self.container addSubview:button];
