如何使用UINavigationController告诉我的UIWebView在新视图中打开链接？
我找到了这个帖子,但是我有点困惑在哪里实现那段代码(我是Objective-C / IPhone的新手)
Clicking a link in UIWebView pushes onto the NavigationView stack
我的视图只包含一个带有UINavigationController的简单WebView
#import <UIKit/UIKit.h>
@interface ContactViewController : UIViewController {
IBOutlet UIWebView *webView1;
}
@property (nonatomic,retain) UIWebView *webView1;
解决方法
假设您的视图控制器(包含webview)已经在导航控制器中,这里有一些步骤.
在.h内 – 确保您的视图控制器符合webview委托
UIViewController <UIWebViewDelegate>
在.m中 – 添加以下代码(或者只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;}
