實(shí)用的簡(jiǎn)單富文本--UITextView實(shí)現(xiàn)恬涧，僅供參考焕刮，歡迎學(xué)習(xí)交流舶沿。

在登錄頁(yè)，經(jīng)撑洳ⅲ看到這樣的字眼“xxx即表示同意AAAA和BBBB”括荡，這里記錄一下簡(jiǎn)單的實(shí)現(xiàn)方式，僅供參考溉旋。

直接上代碼

當(dāng)然需要先遵守UITextView的協(xié)議: <UITextViewDelegate>

@property (nonatomic, strong) UITextView *userProtocolAndPrivacyTextView;

[self.view addSubview:self.userProtocolAndPrivacyTextView];

- (UITextView *)userProtocolAndPrivacyTextView {
    if (!_userProtocolAndPrivacyTextView) {
        _userProtocolAndPrivacyTextView = [[UITextView alloc] initWithFrame:CGRectMake(24, 100, [UIScreen mainScreen].bounds.size.width - 48, 30)];
        _userProtocolAndPrivacyTextView.backgroundColor = [UIColor clearColor];
//        _userProtocolAndPrivacyTextView.font = [UIFont regularPingFangFontOfSize:14];
//        _userProtocolAndPrivacyTextView.textColor = [UIColor colorWithRed:165/255.0 green:165/255.0 blue:165/255.0 alpha:1.0];
        _userProtocolAndPrivacyTextView.editable = NO;
        
        _userProtocolAndPrivacyTextView.delegate = self;
        
        _userProtocolAndPrivacyTextView.textContainer.lineFragmentPadding = 0.0;
        
        _userProtocolAndPrivacyTextView.textContainerInset = UIEdgeInsetsMake(0, 0, 0, 0);
        
        _userProtocolAndPrivacyTextView.linkTextAttributes = @{NSForegroundColorAttributeName:[UIColor colorWithRed:35/255.0 green:135/255.0 blue:230/255.0 alpha:1.0]};
        NSString *preTips = [NSString stringWithFormat:@"xx即表示同意"];
        NSString *userProtocol= [NSString stringWithFormat:@"AAAA"];
        NSString *privacyPolicy = [NSString stringWithFormat:@"BBBB"];

        NSString *string = [NSString stringWithFormat:@"%@%@和%@", preTips, userProtocol, privacyPolicy];
        NSMutableAttributedString *privacy = [[NSMutableAttributedString alloc] initWithString:string attributes:@{NSFontAttributeName:[UIFont systemFontOfSize:14], NSForegroundColorAttributeName:[UIColor colorWithRed:165/255.0 green:165/255.0 blue:165/255.0 alpha:1.0]}];
        
        NSRange userProtocolRange = [string rangeOfString:userProtocol];
        NSRange privacyPolicyRange = [string rangeOfString:privacyPolicy];
        
        [privacy addAttribute:NSLinkAttributeName value:@"user://" range:userProtocolRange];
        
        [privacy addAttribute:NSLinkAttributeName value:@"privacy://" range:privacyPolicyRange];

        _userProtocolAndPrivacyTextView.attributedText = privacy;
    }
    return _userProtocolAndPrivacyTextView;
}

接下來(lái)畸冲，看效果圖：

點(diǎn)擊對(duì)應(yīng)的藍(lán)色文字就會(huì)觸發(fā)UITextView的代理方法，如下：

//MARK: -- UITextViewDelegate
- (BOOL)textView:(UITextView *)textView shouldInteractWithURL:(nonnull NSURL *)URL inRange:(NSRange)characterRange interaction:(UITextItemInteraction)interaction  API_AVAILABLE(ios(10.0)) {
    if ([URL.scheme isEqualToString:@"user"]) {
        NSLog(@"AAAA");
    } else if ([URL.scheme isEqualToString:@"privacy"]) {
        NSLog(@"BBBB");
    }
    return YES;
}
