TTTAttributedLabel实现点击label文字进行跳转

需求

点击Label中的某些文字实现跳转界面或者URL,使用TTTAttributedLabel实现,步骤如下:

安装

推荐使用CocoaPods安装

打开终端,cd 到你们的项目文件夹,在你们项目的Podfile文件里面添加一行:

pod 'TTTAttributedLabel'

然后,终端执行命令

pod install

使用

1.遵守 TTTAttributedLabelDelegate 代理协议

2.设置基本的属性


NSString *text  = @"点其他的字都没有用,点我才能跳转";
   TTTAttributedLabel *label = [[TTTAttributedLabel alloc] initWithFrame:CGRectMake(20, 200,300, 50)];
   label.textColor = [UIColor whiteColor];
   
   NSMutableAttributedString *atributeStr = [[NSMutableAttributedString alloc] initWithString:text attributes:@{
                                                                                                                NSForegroundColorAttributeName:[UIColor whiteColor],
                                                                                                                NSFontAttributeName :[UIFont systemFontOfSize:14]
                                                                                                                }];
   label.text = atributeStr;
   label.backgroundColor = [UIColor grayColor];
   label.font = [UIFont systemFontOfSize:14];
   label.numberOfLines = 0;
   label.linkAttributes = @{NSForegroundColorAttributeName:[UIColor blackColor], NSFontAttributeName:[UIFont systemFontOfSize:16.0f]};
   label.activeLinkAttributes = @{NSForegroundColorAttributeName:[UIColor blackColor], NSFontAttributeName:[UIFont systemFontOfSize:16.0f]};
   NSRange serviceRange = [text rangeOfString:@"点我才能跳转"];
   label.delegate = self;
   [self.view addSubview:label];
   [label addLinkToURL:[NSURL URLWithString:@"http://www.baidu.com/"] withRange:serviceRange];

3.实现协议方法


-(void) attributedLabel:(TTTAttributedLabel *)label didSelectLinkWithURL:(NSURL *)url {
   [[UIApplication sharedApplication] openURL:url];
   }
