如何禁用超链接和复制/粘贴菜单在iOS和webviewdidfinishload不叫

Question

我试图禁用超链接和复制/粘贴菜单在iOS UIwebview 所以我GOOGLE了，并有很多答案。 然后我遇到了另一个问题'webviewdidfinishload不叫' 所以我添加我的代码来问你的帮助。 （Iam确定我正确连接IBOutlet）

另外，我还没有想到把mainWebView.delegate = self而不是self.mainWebView.delegate = self 任何人都可以解释它们的区别吗？ 所以IAM不知道我的其他功能，如 [[[mainWebView子视图] lastObject] setScrollEnabled：YES] [[[mainWebView子视图] lastObject] setScrollsToTop：NO]
mainWebView.scalesPageToFit = YES 这些工作或没有。

应该对iOS5的合作，ios6.1 谢谢

在.h文件中

@interface HRViewController : UIViewController <UIWebViewDelegate> 
{ 
    UIWebView *mainWebView; 
} 
@property (strong, nonatomic) IBOutlet UIWebView *mainWebView; 

@end 

---

在.m文件

@interface HRViewController() 

@end 

@implementation HRViewController 

@synthesize mainWebView; 

- (void)viewDidLoad 
{ 
    [self startWebView]; 
    [super viewDidLoad]; 
} 

- (void)startWebView 
{ 
    mainWebView.delegate = self; 

    [[[mainWebView subviews] lastObject] setScrollEnabled:YES]; 
    [[[mainWebView subviews] lastObject] setScrollsToTop:NO]; 
    mainWebView.scalesPageToFit = YES; 

    mainWebView = [[UIWebView alloc] initWithFrame:self.view.bounds]; 
    mainWebView.scalesPageToFit = YES; 
    [self.view addSubview:self.mainWebView]; 

    NSURL *url = [NSURL URLWithString:/" @"http://www.mysite.com" "/]; 
    NSURLRequest *request = [NSURLRequest requestWithURL:url]; 

    [mainWebView loadRequest:request]; 
} 

- (void)webViewDidFinishLoad:(UIWebView *)WebView { 
    NSLog(@"finish"); 

    [WebView stringByEvaluatingJavaScriptFromString: @"document.documentElement.style.webkitUserSelect='none';"]; 
    [WebView stringByEvaluatingJavaScriptFromString: @"document.documentElement.style.webkitTouchCallout='none';"]; 
} 

- (void)webViewDidStartLoad:(UIWebView *)mainWebView { 
    NSLog(@"start"); 
} 

- (void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error { 
    NSLog(@"Error for WEBVIEW: %@", [error description]); 
} 

EDIED 我用下面的代码，但仍然无法正常工作... 没有这些d oesnt工作!!!!!

- (BOOL)canPerformAction:(SEL)action withSender:(id)sender 
{ 
    NSLog(@"canPerformAction: %@",NSStringFromSelector(action)); 
    if (action == @selector(copy:) || 
     action == @selector(paste:)|| 
     action == @selector(cut:)) { 
     return NO; 
    } 
    return NO; 
} 

这

- (BOOL)canPerformAction:(SEL)action withSender:(id)sender 
{ 
    UIMenuController *menuController = [UIMenuController sharedMenuController]; 
    if (menuController) { 
     [UIMenuController sharedMenuController].menuVisible = NO; 
    } 
    return NO; 
} 

甚至这个 - （无效）viewDidLoad中{ mainWebView.delegate =自我; }

- (void)webViewDidFinishLoad:(UIWebView *)webView { 
    NSLog(@"finish"); 
    // Disable user selection 
    [webView stringByEvaluatingJavaScriptFromString:@"document.documentElement.style.webkitUserSelect='none';"]; 
    // Disable callout 
    [webView stringByEvaluatingJavaScriptFromString:@"document.documentElement.style.webkitTouchCallout='none';"]; 
} 

也在本 - （无效）viewDidLoad中{ [自长按：self.mainWebView]; }

- (void)longPress:(UIView *)webView { 
    UILongPressGestureRecognizer* longPress = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(handleLongPress)]; 

    longPress.allowableMovement=100; 
    longPress.minimumPressDuration=0.3; 
    longPress.delaysTouchesBegan=YES; 
    longPress.cancelsTouchesInView=YES; 
    [webView addGestureRecognizer:longPress]; 
} 

// I just need this for the selector in the gesture recognizer. 
- (void)handleLongPress { 

} 

请帮我..它让我发疯，现在一个星期..

要隐藏复制/粘贴菜单：

覆盖的canPerformAction:withSender:方法返回NO为您不希望允许的操作：

- (BOOL)canPerformAction:(SEL)action withSender:(id)sender 
{ 
    if (action == @selector(paste:)) 
     return NO; 

    if (action == @selector(select:)) 
     return NO; 

    if (action == @selector(selectAll:)) 
     return NO; 

    return [super canPerformAction:action withSender:sender]; 
} 

另一种方式：

- (BOOL)canPerformAction:(SEL)action withSender:(id)sender 
{ 
    UIMenuController *menuController = [UIMenuController sharedMenuController]; 
    if (menuController) { 
     [UIMenuController sharedMenuController].menuVisible = NO; 
    } 
    return NO; 
}

你可以得到答案从this site这个问题。

关于UIWebView：

如果使用则ARC只写，

@property (strong, nonatomic) IBOutlet UIWebView *mainWebView; 

无需@synthesize的财产，其他明智的，

@interface HRViewController : UIViewController <UIWebViewDelegate> 
{ 
    UIWebView *mainWebView; 
} 

@property (nonatomic,retain) IBOutlet UIWebView *mainWebView; 

@end 

// .m file 

- (void)viewDidLoad 
{ 
    mainWebView = [[UIWebView alloc] initWithFrame:self.view.bounds]; 
    mainWebView.scalesPageToFit = YES; 
    mainWebView.delegate = self; 

    [[[mainWebView subviews] lastObject] setScrollEnabled:YES]; 
    [[[mainWebView subviews] lastObject] setScrollsToTop:NO]; 
    mainWebView.scalesPageToFit = YES; 

    [self.view addSubview:self.mainWebView]; 

    NSURL *url = [NSURL URLWithString:@"http://www.mysite.com"]; 
    NSURLRequest *request = [NSURLRequest requestWithURL:url]; 
    [mainWebView loadRequest:request]; 
} 

这可能是有益的为你。
