iOS关于YYLabel的富文本点击事件

最近做了一个有关用户勾选《用户协议》和《隐私政策》的功能，最开始使用系统自带的UItextView的富文本功能，实现图文并排点击事件，但是点击高亮的文字和图片后，先会变灰，再进行响应事件。

折腾了半天没有解决，最后直接使用了YYLabel来实现这个功能。

GitHubdemo地址

效果图如下

步骤一：导入YYText框架

步骤二：添加代码

- (void)viewDidLoad {
    [super viewDidLoad];
    _yyLabel = [[YYLabel alloc]initWithFrame:CGRectMake(20, 100, self.view.bounds.size.width - 40, 40)];
    _yyLabel.textVerticalAlignment = YYTextVerticalAlignmentCenter;
    _yyLabel.textAlignment = NSTextAlignmentCenter;
    [self.view addSubview:_yyLabel];
    [self protocolIsSelect:NO];
}

- (void)protocolIsSelect:(BOOL)isSelect{
    //设置整段字符串的颜色
    UIColor *color = self.isSelect ? [UIColor blackColor] : [UIColor lightGrayColor];
    NSDictionary *attributes = @{NSFontAttributeName:[UIFont fontWithName:@"PingFangSC-Regular" size:12], NSForegroundColorAttributeName: color};
    
    NSMutableAttributedString *text = [[NSMutableAttributedString alloc] initWithString:@"  注册即表示同意《用户协议》和《隐私政策》" attributes:attributes];
    //设置高亮色和点击事件
    [text yy_setTextHighlightRange:[[text string] rangeOfString:@"《用户协议》"] color:[UIColor orangeColor] backgroundColor:[UIColor clearColor] tapAction:^(UIView * _Nonnull containerView, NSAttributedString * _Nonnull text, NSRange range, CGRect rect) {
        NSLog(@"点击了《用户协议》");
    }];
    //设置高亮色和点击事件
    [text yy_setTextHighlightRange:[[text string] rangeOfString:@"《隐私政策》"] color:[UIColor orangeColor] backgroundColor:[UIColor clearColor] tapAction:^(UIView * _Nonnull containerView, NSAttributedString * _Nonnull text, NSRange range, CGRect rect) {
        NSLog(@"点击了《隐私政策》");

    }];
    //添加图片
    UIImage *image = [UIImage imageNamed:self.isSelect == NO ? @"unSelectIcon" : @"selectIcon"];
    NSMutableAttributedString *attachment = [NSMutableAttributedString yy_attachmentStringWithContent:image contentMode:UIViewContentModeCenter attachmentSize:CGSizeMake(12, 12) alignToFont:[UIFont fontWithName:@"PingFangSC-Regular"  size:12] alignment:(YYTextVerticalAlignment)YYTextVerticalAlignmentCenter];
    //将图片放在最前面
    [text insertAttributedString:attachment atIndex:0];
    //添加图片的点击事件
    [text yy_setTextHighlightRange:[[text string] rangeOfString:[attachment string]] color:[UIColor clearColor] backgroundColor:[UIColor clearColor] tapAction:^(UIView * _Nonnull containerView, NSAttributedString * _Nonnull text, NSRange range, CGRect rect) {
        __weak typeof(self) weakSelf = self;
        weakSelf.isSelect = !weakSelf.isSelect;
        [weakSelf protocolIsSelect:self.isSelect];
    }];
    _yyLabel.attributedText = text;
    //居中显示一定要放在这里，放在viewDidLoad不起作用
    _yyLabel.textAlignment = NSTextAlignmentCenter;

}
