如何在UIWebView而不是Safari中打开UITextView Web链接？ [英] How to open UITextView web links in a UIWebView instead of Safari?

问题描述

我正在开发和iPhone 3.0应用程序。我正在尝试将UITextView中的Web链接打开到UIWebView而不是Safari。但仍然没有运气。

I'm developing and iPhone 3.0 application. And I'm trying to open web links in a UITextView into a UIWebView instead of Safari. But still no luck.

UITextView 不可编辑，它可以完美地检测网页链接并在Safari中打开它们。

The UITextView is not editable, and it perfectly detects web links and open them in Safari.

如何避免这种情况？如何获取该URL以便我可以使用我自己的 UIWebView ？

How to avoid that? How to grab that url so i can use with my own UIWebView?

推荐答案

最简单的方法是覆盖 webView：decisionPolicyForNavigationAction：request：frame：decisionListener： on UITextView 如下所示：

The simplest way is to override the webView:decidePolicyForNavigationAction:request:frame:decisionListener: method on UITextView like so:

@interface UITextView (Override)
@end

@class WebView, WebFrame;
@protocol WebPolicyDecisionListener;

@implementation UITextView (Override)

- (void)webView:(WebView *)webView decidePolicyForNavigationAction:(NSDictionary *)actionInformation request:(NSURLRequest *)request frame:(WebFrame *)frame decisionListener:(id < WebPolicyDecisionListener >)listener
{
    NSLog(@"request: %@", request);
}
@end

这将影响所有您的应用程序中的UITextView s。如果你只在一个视图上需要这个，请创建一个子类并覆盖该方法。

This will affect all UITextViews in your application. If you only require this on a single view, create a subclass and override the method on that.

_{注意：这在技术上是一个私有API，可以删除随时。无法通过公共API执行此操作。}

编辑：从iOS 7.0开始，在上引入了一种新方法UITextViewDelegate 支持此功能。有关详细信息，请参阅nihad的答案。

edit: as of iOS 7.0 a new method has been introduced on UITextViewDelegate to support this. See nihad's answer for details.
