TTTAttributedLabel链接正在设置样式但不可点击

问题描述

我一直在研究让可点击链接正常工作的解决方案。我可以在使用UITextView + NSAttributedString时使用它，但是当它是UITableViewCell时它不会正确地自动布局。

I've been looking into a solution to getting clickable links working. I can get this working when using UITextView + NSAttributedString but it just doesn't autolayout properly when it's a UITableViewCell.

现在我已经将TTTAttributedLabel添加到我的项目中了完美地调整视图的样式。链接也变为蓝色并带下划线。

Now I've added the TTTAttributedLabel to my project and it styles the views just perfectly. The links also turn blue and are underlined.

但是点击它们什么都不做。我在我的控制器上实现了TTTAttributedLabelDelegate，在storyboard实现MyLabel中制作了标签（它只是扩展了TTTAttributedLabel并具有委托选项，因为我希望它们在同一个函数中触发）。现在我已经将控制器设置为我认为可能无法指向自身的委托。

However clicking them does nothing. I did implement TTTAttributedLabelDelegate on my controller, made the label in the storyboard implement MyLabel (Which just extends TTTAttributedLabel and has the delegate options since I want them to fire inside the same function). For now I've set the controller to be the delegate I was thinking it might not work pointing to itself.

但这些函数都没有被触发，我得到了断点和登录吧。

But none of these functions get fired, I got breakpoints and logs in it.

我实现了didSelectLinkWithUrl和didLongPressLinkWithUrl。

I Implemented didSelectLinkWithUrl and didLongPressLinkWithUrl.

 func attributedLabel(label: TTTAttributedLabel!, didSelectLinkWithURL url: NSURL!) {
        Debug.log("link clicked")
    }
    func attributedLabel(label: TTTAttributedLabel!, didLongPressLinkWithURL url: NSURL!, atPoint point: CGPoint) {
        Debug.log("link long clicked")
    }

Outlet

@IBOutlet weak var content: MyLabel!

MyLabel

import UIKit
import TTTAttributedLabel

import UIKitimport TTTAttributedLabel

class MyLabel : TTTAttributedLabel, TTTAttributedLabelDelegate {

override func didMoveToSuperview() {
    if (self.delegate == nil) {
        self.delegate = self
    }
    self.enabledTextCheckingTypes = NSTextCheckingType.Link.rawValue
    self.userInteractionEnabled = true
}

func attributedLabel(label: TTTAttributedLabel!, didSelectLinkWithURL url: NSURL!) {
    Debug.log("link clicked")
}
func attributedLabel(label: TTTAttributedLabel!, didLongPressLinkWithURL url: NSURL!, atPoint point: CGPoint) {
    Debug.log("link long clicked")
}

任何人都知道我可能缺少什么？

Anyone know what I could be missing?

更新

我发现只需粘贴一个网址f / e 就会变成活跃的，我实际上是可点击的，并且didSelectLinkWithUrl变得可点击，尽管我需要一个属性字符串，它基于HTML字符串。

I found out that just pasting in an url f/e http://example.com becomes active and is actually clickable and the didSelectLinkWithUrl becomes clickable, allthough I need an attributed string and it's based on a HTML String.

推荐答案

不会更新 linkModels 数组，而的实现。我相信这是导致您出现问题的原因。

The implementation of setAttributedText: doesn't update the linkModels array, while the implementation of setText: does. I believe this is what causes your issue.

要解决此问题，请设置标签的 text 属性，而不是 attributedText property。

To resolve, set the label's text property instead of the attributedText property.

还包括此警告：

文档还显示了此示例用法：

The docs also show this example usage:

TTTAttributedLabel *attributedLabel = [[TTTAttributedLabel alloc] initWithFrame:CGRectZero];

NSAttributedString *attString = [[NSAttributedString alloc] initWithString:@"Tom Bombadil"
                                                                attributes:@{
        (id)kCTForegroundColorAttributeName : (id)[UIColor redColor].CGColor,
        NSFontAttributeName : [UIFont boldSystemFontOfSize:16],
        NSKernAttributeName : [NSNull null],
        (id)kTTTBackgroundFillColorAttributeName : (id)[UIColor greenColor].CGColor
}];

// The attributed string is directly set, without inheriting any other text
// properties of the label.
attributedLabel.text = attString;
