Iphone Objective-C UILabel作为超链接

我正在尝试使UILabel成为UIWebView的链接。如何使UILabel作为超链接使用？

一种可能的解决方案是使用UIButtonTypeCustom类型的UIButton，而不是UILabel。它看起来像一个标签，可以点击

您也可以考虑第三方实现，如TTLaband和.P/>< P>您只需检查此链接，这将对您有帮助。请尝试一次并告知它是否对您有帮助。

您可以使用UITapGestureRecognitzer，它可以实现与您所需类似的功能-

UILabel *myLabel = [[UILabel alloc] initWithFrame:];//Define label here as per needs
myLabel.userInteractionEnabled = YES;
UITapGestureRecognizer *gr = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(myAction:)];
[myLabel addGestureRecognizer:gr];
gr.numberOfTapsRequired = 1;
gr.cancelsTouchesInView = NO;
[self.view addSubview:myLabel];

现在采取行动-

- (void) myAction: (UITapGestureRecognizer *) gr {
    // Define actions here
}

我找到了一些超链接UILabe的代码…希望对您有所帮助： 资料来源：

再次感谢你。现在我想我可以用多种方式制作UILabel/Hyperlink。。作为初学者，我发现rishi的答案更容易使用。是的，我知道运用触摸和手势是最简单的方法。如你所愿，我只是提供帮助，而不是为了你的名誉。
