推荐答案

你必须这样做。假设您的UISlider绑定到名为 slider 的变量，请在ViewController.m的viewDidLoad方法中添加此代码：

You have to do this programaticaly. Assuming your UISlider is bound to a variable called slider, add this code in your viewDidLoad method in ViewController.m:

- (void)viewDidLoad {

    [super viewDidLoad];

    CGAffineTransform trans = CGAffineTransformMakeRotation(M_PI * 0.5);
    slider.transform = trans;
}
