调整 UISearchController 栏中范围栏的圆角

Question

我已经按照我想要的方式设置了颜色：

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

但我仍然看到白色没有变圆。

见图：

我该如何解决这个问题？谢谢

Answer 1

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 2

在您的 AppDelegate 中，在顶部添加此代码

    @interface UISegmentedControl (Appearance)

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


@end

@implementation UISegmentedControl (Appearance)

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


@end

然后你可以在 didFinishLaunchingWithOptions 中添加这段代码

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

Answer 3

设置cornerRadius后尝试调用下面的代码。

segmentContrl.clipsToBounds = true
