在UITableViewCell中有超链接的UILabel应该打开safari webbrowser吗？

Question

我有一个UITableViewCell带有两个标签的自定义(UILabel).表格单元格用于显示信息/文本.在其中一些单元格(不是全部)中,以这种方式设置文本:

cell.myTextlabel.text = @"http://www.google.de"

现在我想要点击这个文本/链接,一个safari webbrowser应该打开这个网页.我怎样才能做到这一点？

最好的问候蒂姆.

Answer 1

将userInteractionEnabled设置为标签的YES,并为其添加手势识别器:

myLabel.userInteractionEnabled = YES;

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

然后实现action方法:

- (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]];
    }
}
