关于ios:UIButton-禁用高亮

参考：https://www.itranslater.com/qa/details/2129903136516080640

形式一：设置高亮和 Selected 同样（如果有 title、image 等，也要这样设置，不举荐这个形式）

button.adjustsImageWhenHighlighted = NO;
[button setBackgroundImage:[UIImage imageNamed:@"switch_close"] forState:UIControlStateNormal];
[button setBackgroundImage:[UIImage imageNamed:@"switch_open"] forState:UIControlStateSelected];
[button setBackgroundImage:[UIImage imageNamed:@"switch_open"] forState:UIControlStateSelected | UIControlStateHighlighted];

形式二：UIControlEventAllTouchEvents（举荐）

[button addTarget:self action:@selector(allTouchEventsClick:) forControlEvents:UIControlEventAllTouchEvents];

- (void)allTouchEventsClick:(UIButton *)button{button.highlighted = NO;}

Tip：能够创立一个本人的 Button，方便使用

#import <UIKit/UIKit.h>

NS_ASSUME_NONNULL_BEGIN

@interface TMButton : UIButton

/// 如果里面须要监听 UIControlEventAllTouchEvents 能够应用 block 代替
@property (copy, nonatomic) void(^allTouchEventsClickBlock)(UIButton *button);

@end

NS_ASSUME_NONNULL_END

#import "TMButton.h"

@implementation TMButton

- (instancetype)init
{self = [super init];
    if (self) {[self addTarget:self action:@selector(allTouchEventsClick:) forControlEvents:UIControlEventAllTouchEvents];
    }
    return self;
}

- (void)allTouchEventsClick:(UIButton *)button{
    button.highlighted = NO;
    if(self.allTouchEventsClickBlock){self.allTouchEventsClickBlock(button);
    }
}

@end
