富文本点击事件

1、添加点击属性

NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:@"请遵守以下协议《协议》"];

[attributedString addAttribute:NSLinkAttributeName

                            value:@"xieyi://"

                            range:[[attributedString string] rangeOfString:@"《协议》"]];

2、添加代理- (BOOL)textView:(UITextView *)textView shouldInteractWithURL:(NSURL *)URL inRange:(NSRange)characterRange {

    if ([[URL scheme] isEqualToString:@"xieyi"]) {

        return NO;

    } 

    return YES;

}
