UITextView inside UIAlertView subclass - iphone

Question

I'm trying to put a UITextView inside a custom subclass of UIAlertView that I create using a background image of mine. The UITextView is only for displaying large quantities of text (so the scrolling).
Here is the code of my subclass
- (id)initNarrationViewWithImage:(UIImage *)image text:(NSString *)text{
if (self = [super init]) {
self.backgroundImage = image;
UITextView * textView = [[UITextView alloc] initWithFrame:CGRectZero];
self.textualNarrationView = textView;
[textView release];
self.textualNarrationView.text = text;
self.textualNarrationView.backgroundColor = [UIColor colorWithRed:0.0 green:1.0 blue:0.0 alpha:1.0];
self.textualNarrationView.opaque = YES;
[self addSubview:textualNarrationView];
}
return self;
}
- (void)drawRect:(CGRect)rect {
NSLog(#"DRAU");
CGSize imageSize = self.backgroundImage.size;
[self.backgroundImage drawInRect:CGRectMake(0, 0, imageSize.width, imageSize.height)];
}
- (void)layoutSubviews {
CGSize imageSize = self.backgroundImage.size;
self.textualNarrationView.bounds = CGRectMake(0, 0, imageSize.width - 20, imageSize.height - 20);
self.textualNarrationView.center = CGPointMake(320/2, 480/2);
}
- (void)show{
[super show];
NSLog(#"SCIO");
CGSize imageSize = self.backgroundImage.size;
self.bounds = CGRectMake(0, 0, imageSize.width, imageSize.height);
self.center = CGPointMake(320/2, 480/2);
}
This is my first time subclassing a UIView, I'm surely missing something since the background image appears correctly, the UITextview also but after a fraction of a second it jumps all up (seems like a coordinate problem).

Answer 1

I've finally created my own customized version of UIAlertView and provided a UITextView inside of it. Here is what brought me to do so.
By doing it I experienced a weird behaviour when I was trying to attach the UITextView to a background UIImageView as a subview, it wasn't responsive to touches anymore, the way to make it work as expected was to attach it to the base view and implement the following method
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer
shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer
by making it return YES when encessary.
