如何在iPhone应用程序中添加超链接？ [英] How to add hyperlink in iPhone app?

问题描述

在我的iPhone应用程序中，我需要显示指向网站的超链接

如何在iPhone编程中为网站添加超链接？ b
$ b

实际上，我想使用facebook API将我的应用程序的链接传递到Facebook。

那么我应该如何格式化我的文本

解决方案

div>

这取决于你想放置这个链接。
如果它在一个UITextView，你只需要启用

  textView.text = @ in it：http：// http：//stackoverflow.com; 
 textView.dataDetectorTypes = UIDataDetectorTypeLink; 
  

有关 iOS参考库

或者如果您要以程序方式打开Safari：

  NSURL * url = [[NSURL alloc] initWithString：@http://stackoverflow.com]; 
 [[UIApplication sharedApplication] openURL：url]; 
 [url release]; 
  

EDIT 因此，如果您想在Facebook上分享， Safari打开一个URL，它将显示一个允许用户共享的Facebook页面。这里是一个例子：

  NSString * urlString = @http://stackoverflow.com; 
 //你想分享的url 
 
 NSString * title =页面的标题; 
 //你想在Facebook上显示的标题
 
 NSString * shareUrlString = [NSString stringWithFormat：@http://www.facebook.com/sharer.php?u=% @& t =％@，urlString，title]; 
 //创建一个URL字符串，告诉Facebook你想要共享那个页面
 
 NSURL * url = [[NSURL alloc] initWithString：shareUrlString]; 
 //创建URL对象
 
 [[UIApplication sharedApplication] openURL：url]; 
 //使用您创建的URL启动Safari 
 
 [url release]; 
 //如果不需要，释放对象
  

In my iPhone app, I require to show the hyperlink to a website

How can I add hyperlink for a website in iPhone programming?.

Actually i want to pass the link from my app onto facebook using facebook API.

So how should I format my text such that it works as hyperlink on facebook?

I am still stuck with this issue.

解决方案

It depends where you want to put this link. If it is in a UITextView, you just have to enable

textView.text = @"Some text with link in it : http://http://stackoverflow.com";
textView.dataDetectorTypes = UIDataDetectorTypeLink;

More info on iOS reference library

Or if you want to open Safari programatically :

NSURL *url = [ [ NSURL alloc ] initWithString: @"http://stackoverflow.com" ];
[[UIApplication sharedApplication] openURL:url];
[url release];

EDIT So if you want to share on facebook, you need to tell Safari to open an URL which will display a Facebook page that allows the user to share. Here is an example :

NSString *urlString = @"http://stackoverflow.com";
//The url you want to share

NSString *title = "The Title of the Page";
//The title you want to be displayed on Facebook

NSString *shareUrlString = [NSString stringWithFormat:@"http://www.facebook.com/sharer.php?u=%@&t=%@", urlString , title];
//Create the URL string which will tell Facebook you want to share that specific page 

NSURL *url = [ [ NSURL alloc ] initWithString:shareUrlString ];
//Create the URL object 

[[UIApplication sharedApplication] openURL:url];
//Launch Safari with the URL you created

[url release];
//Release the object if you don't need it
