Question

I can do this in a tabbed application, no problem, but getting it to work in a single-view application (using xib) is driving me crazy.

I’ve created a new class, WebViewController. The header is:

#import <Foundation/Foundation.h>
#import "GHViewController.h"

@interface GHWebViewController : UIViewController <UIWebViewDelegate>
{
    IBOutlet UIWebView *webView;
}

@property (nonatomic, retain) UIWebView *webView;

@end

And the implementation is:

#import "GHWebViewController.h"

@implementation GHWebViewController

@synthesize webView = _webView;

-(void)viewDidLoad
{
    [super viewDidLoad];
    NSString *fullURL=@"http://www.amazon.com/Books-by-Joel-Derfner/lm/RVZNXKV59PL51/ref=cm_lm_byauthor_full";
    NSURL *url = [NSURL URLWithString:fullURL];
    NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
    [webView loadRequest:requestObj];
}

@end

So far, so good. But going to the web view is only one option of several available to the user (through bar buttons). So I’ve added a UIWebView to my ViewController but hidden it until the user presses the button to go to the web view.

And here’s where I’m stuck. I’ve tried making this a delegate of that, and that a delegate of the other thing, and I can’t tell what’s right and what’s wrong, and the IBOutlet in WebViewController won’t connect to anything in my ViewController and I’m just getting more and more confused. I tried adding another xib for WebViewController but that just led to disaster. I’m out of my depth here.

So my multi-part question is:

1. Is using a UIWebView as one of several options as I’ve described possible with a single-view application?
2. If so, what do I need to do to accomplish it–thinking of a) delegation, b) code, and c) connections in the User Interface?
3. If not, how should I approach the task instead?

Off to see Total Recall. Perhaps that’ll clear my head….

Answer 1

I’m not quite sure if I fully understand your question; the paragraph before your 3 questions are somewhat confusing…

But some thoughts:

1. You don’t need that ivar in interface. Esp. you shouldn’t have IBOutlet in your ivar declaration. If you need IBOutlet, it should be in your @property declaration rather than your ivar.

2. Maybe you don’t really need an IBOutlet. i.e. you don’t need to put your webView on xib. (you can if you want to, but you don’t need to.)

3. So you can just have an IBAction hooked up with a button. When that button is clicked, you can alloc init your webView (and set its frame), add it to your self.view, and set webview.delegate = self or something.

4. Then you can handle the loadURL and stuff like normal. When you click on that button again (or some other button), you just remove your webview from your view.
