本文介绍如何在iOS应用中使用UITextView显示富文本，并实现对文本内链接（包括网址、电话号码和电子邮件地址）的自动检测及交互处理。

_textView = [[UITextView alloc] initWithFrame:CGRectMake(100, _myView.bottom, 190, 100)];
    _textView.backgroundColor = [UIColor yellowColor];
    
    _textView.text = @"你好吗\n我们是谁术有专攻 桂花村械15801270154 gaoyuqiang30@126.com http://www.baidu.com";
    
    NSDictionary *linkAttributes = @{NSForegroundColorAttributeName: [UIColor blueColor],
                                     NSUnderlineStyleAttributeName: @(NSUnderlineStyleSingle)};
    _textView.linkTextAttributes = linkAttributes;
    _textView.delegate = self;
    _textView.editable = NO;
    _textView.dataDetectorTypes = UIDataDetectorTypeLink | UIDataDetectorTypePhoneNumber | UIDataDetectorTypeAddress;
    
    [self.view addSubview:_textView];
    
    [self testTuple];
    
}

- (BOOL)textView:(UITextView *)textView shouldInteractWithURL:(NSURL *)URL inRange:(NSRange)characterRange {
    if ([URL.scheme isEqualToString:@"tel"]) {
        NSLog(@"phone---");
        return NO;
        
    } else if ([URL.scheme isEqualToString:@"mailto"]) {
        NSLog(@"mail");
        return NO;
        
    } else {
        NSLog(@"url");
        return NO;
    }
    return YES;
}
