Answer 1

用这个，

NSArray *arr = [segmentedControl subviews];
    for (int i = 0; i < [arr count]; i++) {
    UIView *v = (UIView*) [arr objectAtIndex:i];
    NSArray *subarr = [v subviews];
        for (int j = 0; j < [subarr count]; j++) {
            if ([[subarr objectAtIndex:j] isKindOfClass:[UILabel class]]) {
                UILabel *l = (UILabel*) [subarr objectAtIndex:j];
                l.transform = CGAffineTransformMakeRotation(- M_PI / 2.0);
            }
        }
    }

尝试以下代码并进行一些更改...

首先在 .m 文件顶部定义弧度，如下所示。

#define degreesToRadians(x) (M_PI * x / 180.0)

在viewDidLoad:or之后viewWillAppear:，尝试下面的代码......

yoursegControl.transform = 
                CGAffineTransformRotate(segControl.transform, degreesToRadians(90));

*尝试Dropdawn List，这是给你的要求的输出*

嘿，如果您使用此 seg 控件的 Dropdawn 列表，那么它对您的要求也很有用，请参阅...
