UIWebview won't zoom even after setting scalesPageToFit to YES

Question

I have a UIWebview that is loaded as a subview when a user selects a tab on a UISegmentedControl. For some reason, I can not get it to allow pinch/zooming. I set the following code in the viewDidLoad method, so it should work.

self.myWebView = [[[UIWebView alloc] initWithFrame:self.view.frame] autorelease];
self.myWebView.backgroundColor = [UIColor whiteColor];
self.myWebView.scalesPageToFit = YES;
self.myWebView.autoresizingMask = (UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight);
self.myWebView.delegate = self;
[self.view addSubview: myWebView];

I tried loading a UIWebView from a NIB and creating it programmatically with no avail. Is there something I'm missing? What could be causing the webview to ignore pinching and zooming?

Thanks!

Answer 1

I see you are setting the autoresizingMask. Does that mean you have created the UIWebView with an initial size of CGRectZero ? Can you interact with the document at all? I mean, does scrolling/tapping work?

Answer 2

You have to enable multi-touch. Pinch involves more than one finger on the screen:

[myWebView setMultipleTouchEnabled:YES]
