UIWebViewDelegate functions have not been called - objective-c

Question

.h file:
#interface MyView: UIViewController <UIWebViewDelegate> {
UIWebView *webView;
}
.m file:
-(void)viewDidLoad {
CGRect webFrame = [[UIScreen mainScreen] applicationFrame];
webView= [[UIWebView alloc] initWithFrame:webFrame];
webView.delegate = self;
[self.view addSubview:webView];
[webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:#"http://google.com"]]];
}
-(void)webViewDidStartLoad:(UIWebView *)webView {
NSLog(#"start");
}
-(void)webViewDidFinishLoad:(UIWebView *)webView {
NSLog(#"finish");
}
-(void)dealloc {
webView.delegate = nil;
webView = nil;
}
create MyView in another ViewController:
MyView * myView = [[MyView alloc] init];
[self.view addSubView:myView.view];
myView = nil;
myView is set to be nil so its delegate is also destroyed.
To solve this, remove the sentence of myView = nil.
Thank you guys who answered me. I did learnt from your answers.

Answer 1

As srikanth said myview is a controller and it needs to be told its on screen and retained so it doesnt go away AND that is your immediate the real issue in your case (I think). Nobody retains myView.
make it a member variable so it isnt released directly after it gave you its view :).
#interface MyCallerWithDoesTheASI : NSObject {
MyView *myView;
}
#end
or do it right and add it like srikanth said ::
[self addChildViewController:myView];
[self.view addSubview:myView.view];
[myView didMoveToParentViewController:self];
or for example and present myView modal
[self presentViewController:myView animated:NO completion:^{ [[myView dismiss...]; }

MyView is a view controller. And you are treating it like a view, in the second case. If you want to add a view of a view controller directly, it will not get all of the view controller methods called. To be able to get the correct functionality, you will have to do some thing different.
Assuming you are in another view controller then in the other view controller, when ever you want to add the view of MyView view controller, do the following
[self addChildViewController:myView];
[self.view addSubview:myView.view];
[myView didMoveToParentViewController:self];
But even before doing that, please use correct naming convention. If you are naming a subclass of UIViewController as MyView, you will confuse yourself. Name it as MyViewController. That way, you will be able to keep track of stuff better.
