iPhone:- 从标签文本中识别链接

Question

在我的 iPhone 应用程序中，我想以不同的颜色显示标签内的链接(如超链接)。

当有人点击链接时，它应该在 Safari 浏览器中打开链接。

我该怎么做？

听到下面是两个示例示例代码链接，希望对您有所帮助:-

或者你也可以这样做

将标签的 userInteractionEnabled 设置为 YES 并向其添加手势识别器:

myLabel.userInteractionEnabled = YES;

    UITapGestureRecognizer *gestureRec = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(openUrl:)];
    gestureRec.numberOfTouchesRequired = 1;
    gestureRec.numberOfTapsRequired = 1;
    [myLabel addGestureRecognizer:gestureRec];
    [gestureRec release];

Then implement the action method:

    - (void)openUrl:(id)sender
    {
        UIGestureRecognizer *rec = (UIGestureRecognizer *)sender;

        id hitLabel = [self.view hitTest:[rec locationInView:self.view] withEvent:UIEventTypeTouches];

        if ([hitLabel isKindOfClass:[UILabel class]]) {
            [[UIApplication sharedApplication] openURL:[NSURL URLWithString:((UILabel *)hitLabel).text]];
        }
    }
