Tab Bar & Reloading UIWebViews

[n2pb]

Hey Guys,

I'm having a bit of an issue trying to figure out what the proper method is to refresh a a UIWebView when it is one of the Tabs on my Tab Bar (the reason why I suspect this is important to denote is because the view is not getting pushed).

I've got a few tabs, and a tab bar controller all nicely set up.
In 2 of the tabs I have 2 corresponding ViewControllers with WebViews done in in IB, everything is hooked up and works fine.

What I'd like to happen is whenever they flip back and forth between tabs, is for the page to be reloaded whenever that tab is selected.

So I did this...
I created the

- (void)viewWillAppear:(BOOL)animated
{
	[super viewWillAppear:(BOOL)animated];
	[busSchedule reload];
}

and invoked the reload method on the WebView, unfortunately...no dice.
I've also tried a variety of other methods with no luck either.

The UIWebView is loaded in viewDidLoad as such...

- (void)viewDidLoad 
{
	[super viewDidLoad];
	
	NSString *urlAddress = @"http://assets.strose.edu/mobileweb/shuttleschedule/default.aspx";
	NSURL *url = [NSURL URLWithString:urlAddress];
	NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
	[busSchedule loadRequest:requestObj];
}

So I the question is, how exactly do I get this behavior to happen?

Thanks,
Justin

webView.h:

@interface webView : UIViewController {
	IBOutlet UIWebView * busSchedule;
}

webView.m:

@synthesize webview;

- (void)viewDidAppear:(BOOL)animated{
	[super viewDidAppear:animated];
	[busSchedule reload];
}

This worked for me

For some reason [busShedule reload]; doesn't work.
That being said I did recreate the NSURLRequest and throw it in the viewDidAppear, and it properly worked, despite that the reload method didn't.

Thanks!

This is how my viewDidLoad looks like:

- (void)viewDidLoad {
	[super viewDidLoad];
	NSString *address = @"http://assets.strose.edu/mobileweb/shuttleschedule/default.aspx";
	NSURL *url = [NSURL URLWithString:address];
	NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
	[self.busSchedule loadRequest:requestObj];
}

If I throw exactly what you have in viewDidLoad (actually I can remove viewDidLoad entirely because it seems that viewDidAppear is also being called simultaneous to viewDidLoad), but instead put it in viewDidAppear, it works PERFECTLY.

I'm still curious why I can't get the page to refresh by doing it the way you have using just the reload method in the viewDidAppear. But I'm just happy enough to have it working! I'm not really sure why I never thought of doing it that way, I just figured it was "proper" to use the reload method in viewDidAppear.
