how to add UIWebview inside a view by coding - iphone

Question

In my app I dragged a View from the library of the interface builder and linked it to the AppDelegate.
my question is "can I add UIWebView inside the View ?"
and if make a special class (UIView class) for the view which method behaves like viewDidload ?

Answer 1

Yes you can add a UIWebView inside the View.
[UIWebView *aWebView =[[UIWebView alloc] initWithFrame:CGRectMake(x,y,width,height)]; aWebView.delegate=self;
[self.view addSubview:aWebView];
[aWebView release];
In the above code you set the delegate of the WebView as self. So you can use the delegate methods of UIWebView like
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
- (void)webViewDidFinishLoad:(UIWebView *)webView
Refer this link for more details.

Answer 2

Yes you can simply use -
In your h file add
#interface YourView:UIView<UIWebViewDelegate>{
in your m file add
CGRect frame = CGRectMake(0,0,200,200);
UIWebView *webView =[[UIWebView alloc] initWithFrame:frame)];
webView.delegate = self;
[self addSubview:webView];

Answer 3

CGRect rect=CGRectMake(x,y,width,height) ;
UIWebView *webView1 =[[UIWebView alloc] initWithFrame:rect)];
webView1.delegate=self;
[self.view addSubview:webView1];
[webView1 release];

Answer 4

If you view's outlet is named myView:
.h file
#interface myViewController:UIViewController <UIWebViewDelegate> {
IBOutlet UIView *myView;
}
.m file
UIWebView *,myWebView = [[UIWebView alloc] initWithFrame:CGRectMake(0,0,myView.frame.size.width,myView.frame.size.height)];
myWebView.delegate = self;
[myView addSubView:myWebView];
It's not necissary to create another subclass to listen for deleagte methods of your view, i would now treat your UIView as a UIWebView and thus use UIWebView's delegate methods, like so:
- (void)webViewDidStartLoad:(UIWebView *)webView {
NSLog(#"started loading");
}
more delegate methods can be found here in the documentation. You could also use NSNotificationCenter to listen for your own events application wide if you wish to fire something in a different class when the UIWebView is loaded.
