Assuming you have the following instances, that are also added to your UIView:

假設您有以下實例，那么這些實例也會添加到您的UIView中：

UITextView *textView;
UIWebView *webView;

and textView contains the URL string, you can load the contents of the URL into webView, as follows:

而textView包含URL字符串，可以將URL的內容加載到webView中，如下所示：

NSURL *url = [NSURL URLWithString:textView.text];
NSURLRequest *req = [NSURLRequest requestWithURL:url];
[webView loadRequest:req];

You can follow these steps:

您可以按照以下步驟操作：

1. Tick on the following properties in UITextView taken from Xib or Storyboard.
2. 勾選從Xib或Storyboard獲取的UITextView中的以下屬性。

OR write these for textview taken dynamically.

或者為動態采取的textview寫下這些。

textview.delegate=self;
textview.selectable=YES;
textView.dataDetectorTypes = UIDataDetectorTypeLink;

2. Now write the below delegate method :
3. 現在編寫下面的委托方法：

-(BOOL)textView:(UITextView *)textView shouldInteractWithURL:(NSURL *)URL inRange:(NSRange)characterRange
{
 NSLog(@"URL: %@", URL);
//You can do anything with the URL here (like open in other web view).
    return NO;
}

I think you are searching for that.

我想你正在尋找那個。

The UITextView has the capability to detect URLs and embed hyperlinks accordingly. You can turn that option on in:

UITextView能夠檢測URL並相應地嵌入超鏈接。您可以打開該選項：

myTextView.dataDetectorTypes = UIDataDetectorTypeLink;

Then you need to configure your app to trap this URL request and let your application handle it. I published a boilerplate class on github that does this, which might be the easiest route: http://github.com/nbuggia/Browser-View-Controller--iPhone-.

然后，您需要配置您的應用程序以捕獲此URL請求並讓您的應用程序處理它。我在github上發布了一個樣板類來執行此操作，這可能是最簡單的路線：http：//github.com/nbuggia/Browser-View-Controller--iPhone-。

The first step is to sub-class UIApplication so you can override who gets to take action on the 'openUrl' request. Here's what that class might look like:

第一步是對UIApplication進行子類化，以便覆蓋誰可以對'openUrl'請求采取行動。以下是該類的外觀：

#import <UIKit/UIKit.h>
#import "MyAppDelegate.h"

@interface MyApplication : UIApplication

-(BOOL)openURL:(NSURL *)url;

@end


@implementation MyApplication

-(BOOL)openURL:(NSURL *)url 
{
    BOOL couldWeOpenUrl = NO;

    NSString* scheme = [url.scheme lowercaseString];
    if([scheme compare:@"http"] == NSOrderedSame 
        || [scheme compare:@"https"] == NSOrderedSame)
    {
        // TODO - Update the cast below with the name of your AppDelegate
        couldWeOpenUrl = [(MyAppDelegate*)self.delegate openURL:url];
    }

    if(!couldWeOpenUrl)
    {
        return [super openURL:url];
    }
    else
    {
        return YES;
    }
}


@end

Next, you need to update main.m to specify MyApplication.h as being the bonified delegate for your UIApplication class. Open main.m and change this line:

接下來，您需要更新main.m以將MyApplication.h指定為UIApplication類的bonified委托。打開main.m並更改此行：

int retVal = UIApplicationMain(argc, argv, nil, nil);

to this

對此

int retVal = UIApplicationMain(argc, argv, @"MyApplication", nil);

Finally, you need to implement the [(MyAppDelegate*) openURL:url] method to have it do what ever you would like with the URL. Like maybe open up a new view controller with a UIWebView in it, and show the URL. You could do something like this:

最后，您需要實現[（MyAppDelegate *）openURL：url]方法，讓它按照您希望的URL進行操作。就像打開一個帶有UIWebView的新視圖控制器一樣，並顯示URL。你可以這樣做：

- (BOOL)openURL:(NSURL*)url
{
    BrowserViewController *bvc = [[BrowserViewController alloc] initWithUrls:url];
    [self.navigationController pushViewController:bvc animated:YES];
    [bvc release];

    return YES;
}

Hopefully that should work for you.

希望這應該對你有用。
