导航栏“返回”关闭模态视图的按钮

我正在尝试为我的应用程序中的网站创建类似自己的“adBanner”的内容。

横幅是一个带有图像的按钮，实际上是横幅图形。

[_adBanner setBackgroundImage:[UIImage imageNamed:@"test_banner.png"] forState:UIControlStateNormal];
_adBanner.opaque = YES; 
[self.view addSubview:_adBanner];
[(UIButton*) _adBanner addTarget:self action:@selector(showWebView:) forControlEvents:UIControlEventTouchUpInside];

[_adBanner release];

翻转视图的函数

- (IBAction)showWebView:(id)sender {    

XLog ("Button Clicked");

WebViewController *_webViewController = [[WebViewController alloc] init];


_webViewController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentModalViewController:_webViewController animated:YES];

}

这是我在 _webViewController 中

编写了一个导航栏

我想显示一个带有 url 的 UIWebView 首先，我用标题WebViewController.m

// Setting Navigation Bar
CGRect navBarRect = CGRectMake(0.0f, 0.0f, 320.0f, 44.0f);
navBar = [ [ UINavigationBar alloc ] initWithFrame: CGRectMake(navBarRect.origin.x, navBarRect.origin.y, navBarRect.size.width, 45.0f)];
[ navBar setDelegate: self.view ];
[ self.view addSubview: navBar ];
[ navBar release];

// Setting TitleString
NSString* adClientTitleString = [ [ NSString alloc] initWithString:@"Client" ];
// Setting Title
[ navBar pushNavigationItem: [ [ UINavigationItem alloc ] initWithTitle:adClientTitleString ] ];
[ navBar setDelegate: self];

：现在我创建了一个后退按钮

[ navBar showButtonsWithLeftTitle: @"Zurück" rightTitle:nil leftBack: YES];

我的问题是如何制作我的后退按钮再次关闭模态视图？或者我该如何设置动作？谢谢你的帮助

I´m trying to create something like an own "adBanner" for a website in my app.

The Banner is a Button with an image, which is actually the banner graphic.

[_adBanner setBackgroundImage:[UIImage imageNamed:@"test_banner.png"] forState:UIControlStateNormal];
_adBanner.opaque = YES; 
[self.view addSubview:_adBanner];
[(UIButton*) _adBanner addTarget:self action:@selector(showWebView:) forControlEvents:UIControlEventTouchUpInside];

[_adBanner release];

here is my function for flipping the view

- (IBAction)showWebView:(id)sender {    

XLog ("Button Clicked");

WebViewController *_webViewController = [[WebViewController alloc] init];


_webViewController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentModalViewController:_webViewController animated:YES];

}

in my _webViewController I want to show a UIWebView with an url

First I coded a Navigation Bar with Title

WebViewController.m :

// Setting Navigation Bar
CGRect navBarRect = CGRectMake(0.0f, 0.0f, 320.0f, 44.0f);
navBar = [ [ UINavigationBar alloc ] initWithFrame: CGRectMake(navBarRect.origin.x, navBarRect.origin.y, navBarRect.size.width, 45.0f)];
[ navBar setDelegate: self.view ];
[ self.view addSubview: navBar ];
[ navBar release];

// Setting TitleString
NSString* adClientTitleString = [ [ NSString alloc] initWithString:@"Client" ];
// Setting Title
[ navBar pushNavigationItem: [ [ UINavigationItem alloc ] initWithTitle:adClientTitleString ] ];
[ navBar setDelegate: self];

and now I created a back Button

[ navBar showButtonsWithLeftTitle: @"Zurück" rightTitle:nil leftBack: YES];

My question Is How I can make my back Button to dismiss the Modal View again ?
Or how can I set the action ?? Thank You for helping

如果您之后使用此代码，那么它将起作用。

    navBar.topItem.leftBarButtonItem =[UIBarButtonItem alloc]initWithTitle:@"Back" style:UIBarButtonItemStylePlain target:self action:@selector(backButtonItemToDismissModal)];


-(void)backButtonItemToDismissModal{

    [self dismissModalViewControllerAnimated:YES];

}

If you use this code after that then it will work.

    navBar.topItem.leftBarButtonItem =[UIBarButtonItem alloc]initWithTitle:@"Back" style:UIBarButtonItemStylePlain target:self action:@selector(backButtonItemToDismissModal)];


-(void)backButtonItemToDismissModal{

    [self dismissModalViewControllerAnimated:YES];

}
