The simplest way is just to add a UIWebView when the button gets pressed. Add this method to your ViewController.m and have this be performed when the button gets pressed.
Programmatically:
//This method should get called when you want to add and load the web view
- (void)loadUIWebView
{
UIWebView *webView = [[UIWebView alloc] initWithFrame:self.view.bounds]; //Change self.view.bounds to a smaller CGRect if you don't want it to take up the whole screen
[webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:currentURL]]];
[self.view addSubview:webView];
[webView release];
}
Using Interface Builder:
1) Add a UIWebView object to your interface.
2) Set the "hidden" property to checked (in the "Attributes Inspector" window in Interface Builder). You'll keep it hidden until you want to show it.
3) Add the following code to your ViewController.h, below the other @property lines:
@property (nonatomic, retain) IBOutlet UIWebView *webView;
4) Add the following line below the @synthesize in your ViewController.m
@synthesize webView;
And add [webView release]; in the dealloc method.
5) Go back into IB and click on File's Owner, and connect the webView outlet to the webView you created.
6) Add the following method instead of the method I showed above (for the programmatic example):
//This method should get called when you want to add and load the web view
- (void)loadUIWebView
{
[self.webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:currentURL]]];
self.webView.hidden = NO;
}
You could set up an IBAction method to respond to the button press, but it sounds like you already have the button press working, so I wouldn't bother with that now.
As far as adding a button above the web view, you can either subclass web view and add the button there, or just have a separate button you define in your nib or programmatically and have that hide the webView to "get rid of it".
