將URL從一個UIWebView傳遞到另一個UIWebview

Question

當用戶點擊當前的鏈接UIWebView時，新視圖被壓入包含UIWebView的navigationController堆棧。我想將這個被觸動的網址傳遞給這個新的UIWebView。我如何去做這件事？

Answer 1

在你UIWebView委託：

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType { 
    if(navigationType == UIWebViewNavigationTypeLinkClicked) { 
     YourWebViewController* vc = [[YourWebViewController alloc] initWithURL:[request URL]]; 
     [self.navigationController pushViewController:vc animated:YES]; 
     [vc release]; 
     return NO; 
    } 
    return YES; 
} 

然後你只需要實現您的自定義視圖控制器的初始化：

- (id)initWithURL:(NSURL*)url { 
    self = [super init]; 
    if(self) { 
     myURL = [url retain]; 
    } 
    return self; 
} 

然後在適當的時候加載它，就像viewDidAppear:

- (void)viewDidAppear:(BOOL)animated { 
    [webView loadRequest:[NSURLRequest requestWithURL:myURL]]; 
}
