如何从 iphone 应用程序查询调用 safari 中的 weblink

发布于 2024-12-16 12:58:39 字数 1012 浏览 1 评论 0原文

我正在解析 xml 文件以获取电话号码值（aMarker.web= weblink）。其中标记是我在解析器控制器中获取的 xml 文件中的属性。我可以使用以下方法在按钮标题上设置此 webLink 字符串，

        [w_Bcard setTitle:[NSString stringWithFormat:@"%@",aMarker.web] forState:UIControlStateNormal];

但通过点击按钮我无法拨打该号码。请参阅我的代码

 - (IBAction)weblink_BcardVeiw
   {

NSIndexPath *selectedIndexPath = [self.tableView indexPathForSelectedRow];

marker *aMarker = (marker *)[appDelegate.markers  objectAtIndex:selectedIndexPath.row];
 for (int selectedIndexPath = 0; selectedIndexPath < [appDelegate.markers count];  selectedIndexPath++)
 {
    NSString *utfString = [NSString stringWithFormat:@"%@",aMarker.web];        
    NSURL *url = [NSURL URLWithString:utfString];

    [[UIApplication sharedApplication] openURL:url];
    NSLog(@"%@",url);
   }
[self.tableView deselectRowAtIndexPath:selectedIndexPath animated:YES];

通过 NSloging m 获取相应的 url，但无法在 safari 中打开此 url。我应该在哪里更正上面的代码？？？我还想通过传递动态字符串 aMarker.email 来调用邮件应用程序。您也可以建议该代码吗？

I am parsing xml file to get phone number values (aMarker.web= weblink). Where marker is attributes in xml file which I am fetching in my parser controller. I am able to set this webLink string on Button title by using

        [w_Bcard setTitle:[NSString stringWithFormat:@"%@",aMarker.web] forState:UIControlStateNormal];

But by tapping button I am not able to call the number. See my code

 - (IBAction)weblink_BcardVeiw
   {

NSIndexPath *selectedIndexPath = [self.tableView indexPathForSelectedRow];

marker *aMarker = (marker *)[appDelegate.markers  objectAtIndex:selectedIndexPath.row];
 for (int selectedIndexPath = 0; selectedIndexPath < [appDelegate.markers count];  selectedIndexPath++)
 {
    NSString *utfString = [NSString stringWithFormat:@"%@",aMarker.web];        
    NSURL *url = [NSURL URLWithString:utfString];

    [[UIApplication sharedApplication] openURL:url];
    NSLog(@"%@",url);
   }
[self.tableView deselectRowAtIndexPath:selectedIndexPath animated:YES];

By NSloging m getting respective url but not able to open this url in safari. Where should I correct the above code???
I also want to call mail application by passing dynamic string aMarker.email. Can you suggest that code also.

您将使用数据检测器。例如，您可能会这样做：

- (void)dataDetectorPassInRange:(NSRange)range
{
    if (![self dataDetectorTypes])
            return;

    NSError* error = NULL;
    NSDataDetector* detector = [NSDataDetector dataDetectorWithTypes:self.dataDetectorTypes error:&error];
    NSAssert(error == nil, @"Problem creating the link detector: %@", [error localizedDescription]);
    NSString* string = [self yourStringStore];

    [detector enumerateMatchesInString:string options:0 range:range usingBlock:^(NSTextCheckingResult* match, NSMatchingFlags flags, BOOL* stop){
            NSRange matchRange = [match range];
            if([match resultType] == NSTextCheckingTypePhoneNumber)
            {
                    NSString* phoneNumber = [match phoneNumber];
                    NSURL* phoneURL = [NSURL URLWithString:phoneNumber];
                    [[UIApplication sharedApplication] openURL:phoneURL];
            }
    }];
}

我在某些代码中做了类似的事情，我创建了一个替换 UITextView，它可以处理属性文本（样式）并检测电话号码、链接和地址等内容。基本上你想要的是数据检测器。

You would use a data detector. For instance, you might do something like this:

- (void)dataDetectorPassInRange:(NSRange)range
{
    if (![self dataDetectorTypes])
            return;

    NSError* error = NULL;
    NSDataDetector* detector = [NSDataDetector dataDetectorWithTypes:self.dataDetectorTypes error:&error];
    NSAssert(error == nil, @"Problem creating the link detector: %@", [error localizedDescription]);
    NSString* string = [self yourStringStore];

    [detector enumerateMatchesInString:string options:0 range:range usingBlock:^(NSTextCheckingResult* match, NSMatchingFlags flags, BOOL* stop){
            NSRange matchRange = [match range];
            if([match resultType] == NSTextCheckingTypePhoneNumber)
            {
                    NSString* phoneNumber = [match phoneNumber];
                    NSURL* phoneURL = [NSURL URLWithString:phoneNumber];
                    [[UIApplication sharedApplication] openURL:phoneURL];
            }
    }];
}

I do something like this in some code where I create a replacement UITextView which can handle attributed text (styled) and detect things like phone numbers, links and addresses. Basically what you want are data detectors.
