UITableViewCell 内的 UITextView - 如果不点击链接，则触摸通过

问题描述

我试图在本身可点击的 TableViewCell 中利用带有数据检测器类型的 UITextView 的优势.

I'm trying to have the advantage of the UITextView with Data Detector Types inside a TableViewCell that is itself clickable.

唯一的问题是，我需要 UITextView 的链接是可点击的，所以 userInteractionEnabled = YES，不幸的是，这将阻止任何触摸通过 UITableViewCell.

The only thing is, I need the UITextView's links to be clickable, so userInteractionEnabled = YES, unfortunately this will prevent any touch going through to the UITableViewCell.

当然不能编辑 UITextView，我也将它子类化，拒绝它成为第一响应者以避免选择其中的文本.

Of course the UITextView can't be edited, I also subclassed it refusing it to be first responder to avoid selecting text in it.

我唯一需要的是检测用户是否触摸 UITextView，检查它是否是一个链接，如果它正在打开链接，否则将触摸重定向到 UITableViewCell.

The only thing I need, is detecting that if a user touch the UITextView, check if it was a link, if it is then opening the link, otherwise redirect the touch on the UITableViewCell.

知道如何做到这一点吗?

any idea how can this be done ?

很像 Twitter 应用程序(我们可以点击行或链接...)

much like the twitter App (we can either click on the row, or on the link...)

推荐答案

我知道这个问题很久以前就有人问过了，但是对于某些应用程序来说，它仍然非常需要这种行为，因为它有一个带有 UIDataDetectors 的可点击单元.

I know that this question has been asked a while ago, but the behaviour is still very much needed for some app to have a clickable Cell with UIDataDetectors.

所以这是我为在 UITableView 中适应这种特定行为而编写的 UITextView 子类

So here's the UITextView subclass I made up to fit this particular behaviour in a UITableView

-(id) initWithFrame:(CGRect)frame {
    self = [super initWithFrame:frame];
    if (self) {
        self.delegate = self;
    }
    return self;
}

- (BOOL)canBecomeFirstResponder {
    return NO;
}

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    UIView *obj = self;

    do {
        obj = obj.superview;
    } while (![obj isKindOfClass:[UITableViewCell class]]);
    UITableViewCell *cell = (UITableViewCell*)obj;

    do {
        obj = obj.superview;
    } while (![obj isKindOfClass:[UITableView class]]);
    UITableView *tableView = (UITableView*)obj;

    NSIndexPath *indePath = [tableView indexPathForCell:cell];
    [[tableView delegate] tableView:tableView didSelectRowAtIndexPath:indePath];
}

- (BOOL)textView:(UITextView *)textView shouldInteractWithURL:(NSURL *)URL inRange:(NSRange)characterRange {
    return YES;
}

您可以修改它以满足您的需要...

You can modify this to fit your needs...
