没有界面构建器的uiwebview(uiwebview without interface builder)

我要切换我的应用程序的一部分：我将实现一个图片的web查看（imageview）。

所以我尝试使用界面构建器，但是有太多错误，所以我更喜欢使用代码！

对于图片，我用这些线：

image = [UIImage imageWithData:[NSData dataWithContentsOfURL:url]]; self.imageView = [[UIImageView alloc] initWithImage:image]; imageView.frame = CGRectMake(0,64,320,367); [self.view addSubview:imageView]; [self.imageView release];

现在，我尝试使用此代码，但没有显示：

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

...

[webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.google.fr"]]]; [self.view addSubview:webView];

如果你知道如何制作....对我来说会很好，

谢谢！

I've to switch a part of my app: I will implement a web view insread of a picture (imageview).

So I tried to make it with the interface builder but there is too many errors so I prefer to use code!

for the pictures, I user those lines :

image = [UIImage imageWithData:[NSData dataWithContentsOfURL:url]]; self.imageView = [[UIImageView alloc] initWithImage:image]; imageView.frame = CGRectMake(0,64,320,367); [self.view addSubview:imageView]; [self.imageView release];

Now, I tried to use this code but nothing's showed:

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

...

[webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.google.fr"]]]; [self.view addSubview:webView];

If you know how to make .... would be nice for me,

THANKS!

在你的h文件中声明：

UIWebView *contentWebView;

并告诉您的viewController您将实现<UIWebViewDelegate>

在viewDidLoad中添加：

contentWebView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)]; contentWebView.delegate = self; contentWebView.multipleTouchEnabled = YES; contentWebView.scalesPageToFit = NO; [self.view addSubview:contentWebView];

在dealloc中不要忘记发布webView：

[contentWebView release];

并实现委托方法：

#pragma mark - #pragma mark WebViewDelegates - (void)webViewDidStartLoad:(UIWebView *)webView{ } - (void)webViewDidFinishLoad:(UIWebView *)webView{ } - (void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error{ }

而且您还需要加载请求。将webView添加到视图后，可以在viewDidLoad中执行以下操作：

[contentWebView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.apple.com/"]]];

Declare in your h file:

UIWebView *contentWebView;

And also tell to your viewController that you will implement <UIWebViewDelegate>

In viewDidLoad Add:

contentWebView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)]; contentWebView.delegate = self; contentWebView.multipleTouchEnabled = YES; contentWebView.scalesPageToFit = NO; [self.view addSubview:contentWebView];

In dealloc don't forget to release the webView:

[contentWebView release];

And implement the delegate methods:

#pragma mark - #pragma mark WebViewDelegates - (void)webViewDidStartLoad:(UIWebView *)webView{ } - (void)webViewDidFinishLoad:(UIWebView *)webView{ } - (void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error{ }

And also you need to load an request. You can doit in viewDidLoad after you have added the webView to your view:

[contentWebView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.apple.com/"]]];
