调整范围条的圆形cornors在UISearchController酒吧

Question

我有颜色全部设为我希望他们用这种方式：

// Scope bar appearance 
[[UISegmentedControl appearanceWhenContainedIn: [UISearchBar class], nil] setTintColor:[UIColor blueColor]]; 
[[UISegmentedControl appearanceWhenContainedIn: [UISearchBar class], nil] setBackgroundColor:[UIColor whiteColor]]; 

但我仍然得到白色透进来并且不是圆的。

见图片：

我该如何解决这个问题？谢谢。

Answer 1

在你的appdelegate顶部

@interface UISegmentedControl (Appearance) 

- (void)setCornerRadius:(CGFloat)cornerRadius UI_APPEARANCE_SELECTOR; 


@end 

@implementation UISegmentedControl (Appearance) 

- (void)setCornerRadius:(CGFloat)cornerRadius { 
    self.layer.cornerRadius = cornerRadius; 
} 


@end 

添加该代码，然后你可以在didFinishLaunchingWithOptions

[[UISegmentedControl appearanceWhenContainedIn: [UISearchBar class], nil] setCornerRadius:5]; 

Answer 2

请试试这个：

segmentContrl.layer.borderColor = <Set_Your_Color>; 
segmentContrl.layer.cornerRadius = 0.5; // You might have to adjust this 
segmentContrl.layer.borderWidth = 1.5f; // You might have to adjust this 

Answer 3

试试下面调用添加以下代码代码设置cornerRadius后。

segmentContrl.clipsToBounds = true
