Question

I have a problem with this code:

Header:

@interface ViewController : UIViewController {
    IBOutlet UITextField *field;
    IBOutlet UIWebView <UIWebViewDelegate> *web;
}

Implementation:

@protocol UIWebViewDelegate;

- (void)viewDidLoad{
    //some other code here
    webView = [[UIWebView alloc] init];
    webView.delegate = self; 
}

I got two problems. The first is that on the line webView = [[UIWebView alloc] init];</code>the compiler generates the following message:Incompatible pointer types assigning to 'UIWebView*_strong' from 'UIWebView'*'.
The second problem is that I get an error on the line <code>webView.delegate = self;</code> that says:
‘Passing ViewController*const_strong to parameter of incompatible type ‘id’`.

Any ideas? Any help will be welcome.

You’ve declared your webView ivar to be a UIWebViewDelegate. You meant to make ViewController a UIWebViewDelegate:

@interface ViewController : UIViewController <UIWebViewDelegate>
