iOS开发之UITextView部分文字添加超链接(iOS10)

将封装好的文件拖到项目中,导入头文件,调用就可以了.如图

类文件主要方法:

/**
 UITextView文字超链接
 
 @param allStr 整个字符串
 @param changeStr 需要更改为超链接的部分字符
 @param changeStrColor 超链接字符颜色
 @param style 超链接字符的样式
 @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
                   value:changeStr
                   range:urlRange];
    [string addAttribute:NSForegroundColorAttributeName
                   value:changeStrColor
                   range:urlRange];
    [string addAttribute:NSUnderlineStyleAttributeName
                   value:@(style)
                   range:urlRange];
    [string endEditing];
    
    
    return string;
    
}

在UITextView需要实现的地方调用,如图

- (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];
    //实现类方法
    textView.attributedText = [ZTextViewHyperLink AllString:@"这里的天气很好,我要到百度上面去买个面膜" ChangeString:@"百度" ChangeStrColor:[UIColor blueColor] StrStyle:NSUnderlineStyleNone ];
    textView.dataDetectorTypes = UIDataDetectorTypeLink;
    [self.view addSubview:textView];
    textView.delegate = self;
    [textView setSelectable: YES];
    
    //非编辑状态下,才能允许跳转
    [textView setEditable:NO];
    
}


/**
  代理方法
 */
- (BOOL)textView:(UITextView *)textView shouldInteractWithURL:(NSURL *)URL inRange:(NSRange)characterRange {
    
    //要打开的超链接
    NSString *urlStr= @"http://www.hao123.com";
    //iOS10,打开跳转链接新方法
    [[UIApplication sharedApplication]openURL:[NSURL URLWithString:urlStr] options:@{} completionHandler:^(BOOL success) {
    }];
    return YES;
}
