提问by Nico AD
How can I tell my UIWebViewto open links in a new View , using a UINavigationController?
如何告诉我UIWebView在新视图中打开链接，使用UINavigationController?
I found this thread, but i m a little confused of where to implement that piece of code (i m new to objective-C/IPhone)
我找到了这个线程，但我对在哪里实现那段代码有点困惑（我是 Objective-C/IPhone 的新手）
Clicking a link in UIWebView pushes onto the NavigationView stack
单击 UIWebView 中的链接会推送到 NavigationView 堆栈上
my view just contains a simple WebViewwith a UINavigationControlleron top
我的观点只包含一个简单WebView的UINavigationController顶部
#import <UIKit/UIKit.h>
@interface ContactViewController : UIViewController {
IBOutlet UIWebView *webView1;
}
@property (nonatomic, retain) UIWebView *webView1;

Here are steps assuming your view controller (that houses the webview) is already within a navigation controller.
以下是假设您的视图控制器（包含 webview）已经在导航控制器中的步骤。
Within the .h - ensure your view controller conforms to the webview delegate
在 .h 中 - 确保您的视图控制器符合 webview 委托
UIViewController <UIWebViewDelegate>
Within the .m - add the following code (or just implement this method with whatever logic you want)
在 .m 中 - 添加以下代码（或仅使用您想要的任何逻辑实现此方法）
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType{
if (navigationType == UIWebViewNavigationTypeLinkClicked) {
YourNextViewController *ynvc = [[[YourNextViewController alloc] initWithNibName:@"YourNextViewController" bundle:nil] autorelease];
ynvc.ivar1 = value1;
ynvc.ivar2 = value2;
UIBarButtonItem *backButton = [[[UIBarButtonItem alloc] initWithTitle:@"Back" style:UIBarButtonItemStyleBordered target:nil action:nil] autorelease];
[[self navigationItem] setBackBarButtonItem:backButton];
[self.navigationController pushViewController:ynvc animated:YES];
return NO;
}
return YES;}

I'm pretty new to objective C / iPhone too, but what I would try,..
我对目标 C/iPhone 也很陌生，但是我会尝试什么，..
Is creating a new viewController for your webview and push it in your UINavigator
正在为您的 webview 创建一个新的 viewController 并将其推送到您的 UINavigator
yourWebViewController *y = [[yourWebViewController alloc] init];
[self.navigationController pushViewController:y animated:YES];
[y release];
