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);@endNS_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
