Here is my code
- (void)embedYouTube:(NSString*)url frame:(CGRect)frame {
UIWebView * videoView;
NSString* embedHTML = @"<html><head><style type=\"text/css\">body {background-color: transparent;color: white;}</style></head><body style=\"margin:0\"><embed id=\"yt\" src=\"%@\" type=\"application/x-shockwave-flash\"width=\"%0.0f\" height=\"%0.0f\"></embed></body></html>";
NSString* html = [NSString stringWithFormat:embedHTML, url, frame.size.width, frame.size.height];
if(videoView == nil) {
videoView = [[UIWebView alloc] initWithFrame:frame];
[self.view addSubview:videoView];
}
[videoView loadHTMLString:html baseURL:nil];
}
so in viewDidLoad I call
[self embedYouTube:@"http://www.youtube.com/watch?v=2mcjR3TsK4s&feature=g-logo&context=G2e376ceFOAAAAAAAAAA" frame:self.view.bounds];
I'm testing it in ipad2 ios 5.0 and it is an error

Thanks for helping
When you defined variable like UIWebView * videoView; it's assumes that it refers to some memory. Usually it refers to nil and all works fine, but in your case it refers to another object and comparing videoView == nil won't work. To avoid it always declare variables and refer it to nil explicity.
UIWebView *videoView = nil;
