点击UILabel部分的手势 [英] Tap Gesture on part of UILabel

问题描述

我可以使用以下代码成功地将轻击手势添加到UITextView的一部分：

I could successfully add tap gestures to a part of UITextView with the following code:

UITextPosition *pos = textView.endOfDocument;// textView ~ UITextView

for (int i=0;i<words*2-1;i++){// *2 since UITextGranularityWord considers a whitespace to be a word

    UITextPosition *pos2 = [textView.tokenizer positionFromPosition:pos toBoundary:UITextGranularityWord inDirection:UITextLayoutDirectionLeft];
    UITextRange *range = [textView textRangeFromPosition:pos toPosition:pos2];
    CGRect resultFrame = [textView firstRectForRange:(UITextRange *)range ];

    UIView* tapViewOnText = [[UIView alloc] initWithFrame:resultFrame];
    [tapViewOnText addGestureRecognizer:[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(targetRoutine)]];
    tapViewOnText.tag = 125;
    [textView addSubview:tapViewOnText];

    pos=pos2;
}

我希望模仿 UILabel中的相同行为。问题是， UITextInputTokenizer （用于标记单个单词）在 UITextInput.h 中声明，并且只有 UITextView & UITextField 符合 UITextInput.h ; UILabel 没有。
这是否有解决办法？

I wish to imitate the same behaviour in a UILabel. The issue is, UITextInputTokenizer (used to tokenize the individual words) is declared in UITextInput.h, and only UITextView & UITextFieldconform to UITextInput.h; UILabel does not. Is there a workaround for this ??

推荐答案

您可以尝试 https://github.com/mattt/TTTAttributedLabel 并添加标签链接。当按下链接时，你会得到一个动作，因此标签点击的一部分只能用于自定义标签的链接部分。我在过去尝试了这个并且它完美无缺，但是我的客户对使用第三方组件不感兴趣，所以使用UIWebView和HTML复制了这个功能。

You could try https://github.com/mattt/TTTAttributedLabel and add a link to the label. When the link is pressed you get a action, so part of the label click works only thing you have to would be customizing the link part of the label. I tried this in the past and it worked flawlessly but my client was not interested in using a third party component so duplicated this functionality using UIWebView and HTML.
