How to insert a WebView into a cocoa app?

Question

I'm rather new with the whole OSX programming, I wanted to stick a WebView into an empty app. Apparently it isn't as simple as sticking a WebView on a window in interface builder and creating an outlet.

IBOutlet WebView *webView;

It gives me a

expected specifier-qualifier-list before 'WebView'

and when I don't use an outlet, it terminates due to uncaught exception. I'm not too sure what these error messages mean.

Seems it isn't that simple!

Answer 1

You also need to add the WebKit framework to your target and forward declare WebView or import the header file:

// header file:
@class WebView; // forward declaration sufficient in header
@interface WhatEver ... {
    WebView* webview;
// ...
@property (assign) IBOutlet WebView *webview;
@end

// implementation file:
#import <WebKit/WebView.h> // if you want to do something with the WebView
@implementation WhatEver
@synthesize webview;
// ...
@end

While trying to solve this problem, I came upon this other post that describes that the WebView cannot be layer-backed (and hence any of its superviews cannot be layer-backed as well, I believe, because of the inheritance of being layer-backed from parent views to subviews). Turning off layer backing worked for me!
