調整範圍條的圓形cornors在UISearchController酒吧

Question

我有顏色全部設爲我希望他們用這種方式：

// 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進來並且不是圓的。

見圖片：

我該如何解決這個問題？謝謝。

Answer 1

在你的appdelegate頂部

@interface UISegmentedControl (Appearance) 

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


@end 

@implementation UISegmentedControl (Appearance) 

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


@end 

添加該代碼，然後你可以在didFinishLaunchingWithOptions

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

Answer 2

請試試這個：

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

試試下面調用添加以下代碼代碼設置cornerRadius後。

segmentContrl.clipsToBounds = true
