將封裝好的文件拖到項目中,導入頭文件,調用就可以了.如圖

/**
 UITextView文字超鏈接

 @param changeStrColor 超鏈接字符顏色
 @param style 超鏈接字符的樣式
 @return 返回的字符串
 */
+(NSMutableAttributedString *)AllString:(NSString *)allStr ChangeString:(NSString *)changeStr ChangeStrColor:(UIColor *)changeStrColor StrStyle:(NSInteger)style {
    
    NSString *str = [NSString stringWithFormat:@"%@", allStr];
    
    NSMutableAttributedString *string = [[NSMutableAttributedString alloc] initWithString:str]; // assume string exists
    NSRange urlRange = [str rangeOfString:changeStr];
    [string addAttribute:NSLinkAttributeName

    [string endEditing];
    
    
    return string;
    
}

在UITextView需要實現的地方調用,如圖

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    
    UITextView * textView = [[UITextView alloc] initWithFrame:CGRectMake(100, 200, 200, 200)];
    textView.backgroundColor =[UIColor whiteColor];
    //實現類方法
    textView.attributedText = [ZTextViewHyperLink AllString:@"這里的天氣很好,我要到百度上面去買個面膜" ChangeString:@"百度" ChangeStrColor:[UIColor blueColor] StrStyle:NSUnderlineStyleNone ];
    textView.dataDetectorTypes = UIDataDetectorTypeLink;
    [self.view addSubview:textView];
    textView.delegate = self;
    [textView setSelectable: YES];
    
    //非編輯狀態下,才能允許跳轉
    [textView setEditable:NO];
    
}


/**
  代理方法
 */
- (BOOL)textView:(UITextView *)textView shouldInteractWithURL:(NSURL *)URL inRange:(NSRange)characterRange {
    
    //要打開的超鏈接
    NSString *urlStr= @"http://www.hao123.com";
    //iOS10,打開跳轉鏈接新方法
    [[UIApplication sharedApplication]openURL:[NSURL URLWithString:urlStr] options:@{} completionHandler:^(BOOL success) {
    }];
    return YES;
}
