单击URL时UITextView崩溃

Question

我的代码中有以下几行,用于向UITextView添加可点击的URL.merchantwebsite是我的UITextView.

self.merchantwebsite.attributedText = [[NSAttributedString alloc] initWithString:@"http://www.crossfit.com" attributes:@{NSLinkAttributeName: @"http://www.crossfit.com"}];
self.merchantwebsite.userInteractionEnabled = YES;

当我单击UITextView时,应用程序会与日志崩溃

有人可以告诉我我做错了什么.

谢谢!

Answer 1

您显然拥有希望URL为NSURL的代码.但是,很简单,NSString 不是 NSURL.试试这样:

self.tv.attributedText = 
    [[NSAttributedString alloc] 
        initWithString:@"http://www.crossfit.com" 
        attributes:
            @{NSLinkAttributeName: [NSURL URLWithString:@"http://www.crossfit.com"]}];
