Iphone 在safari中打开UIWebView链接？UIWebView代理放置

我试图在safari中打开UIWebView的链接，但到目前为止没有成功。我相当肯定我对代表们做了错事。你们能看一下吗

这是我的viewcontroller.m中的内容

（BOOL）webView:（UIWebView*）webView应加载请求： （NSURLRequest*）请求导航类型： （UIWebViewNavigationType）navigationType；{

NSURL *requestURL =[[request URL]retain];
if(([[requestURL scheme]isEqualToString:@"http"])&&(navigationType == 
UIWebViewNavigationTypeLinkClicked)){
return ![[UIApplication sharedApplication]openURL:[requestURL

自动释放]]； } [请求URL发布]； 返回YES；}

很抱歉格式化。无论如何，我的第一个问题是，上面的webView是否应该与我在.h文件中声明的webView相同

我的下一个问题是关于授权webview。这是我的viewcontroller.h

（我知道它不是javascript，但它在这里看起来比在blockquote中更好）

下面是我在.m viewdidload函数中输入的内容（这是一个猜测，我不知道放在哪里，甚至不知道它是否应该是self）

[webView setDelegate:self]

运行此项目时，代码可能根本不存在，链接在应用程序中仍然打开，而不是在safari中。你们能帮我解决我做错了什么，或者给我一些关于如何设置NSLog或其他什么的建议，让我看看哪里出了问题吗？感谢您的帮助
