Slide textview horizontal without using paging - iphone

Question

I`m using a simple Textview in an tabbased application to display some text :) I figerd out how to change the text animated using the following code:
- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {
UITouch *touch = [touches anyObject];
CGPoint currentTouchPosition = [touch locationInView:self];
// To be a swipe, direction of touch must be horizontal and long enough.
if (fabsf(startTouchPosition.x - currentTouchPosition.x) >= HORIZ_SWIPE_DRAG_MIN &&
fabsf(startTouchPosition.y - currentTouchPosition.y) <= VERT_SWIPE_DRAG_MAX)
{
// It appears to be a swipe.
if (startTouchPosition.x < currentTouchPosition.x){
NSString *string = [[NSString alloc]initWithFormat:#"..."];
self.text = string;
}
else{
CGContextRef context = UIGraphicsGetCurrentContext();
[UIView beginAnimations:nil context:context];
//[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:[self superview] cache:YES];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:[self superview] cache:YES];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationDuration:0.5];
[[self superview] exchangeSubviewAtIndex:0 withSubviewAtIndex:1];
[UIView commitAnimations];
[self displayNewText];
}
}
However there is now "slide transition" defined in UIViewAnimationTransition. I know about paging, but I don`t want to use this. Is there an other possibility to have an horizontal slide animation when detecting a horizontal swipe?

Answer 1

I think you are almost there. Intercept touchesMoved:withEvent method just like in your current code and update the visible area of the UIScrollView object.

Answer 2

I hope you don't have to detect touches for your requirement use UIScrollView as parent view for UITextView.
scroll=[[UIScrollView alloc]initWithFrame:CGRectMake(0,40, 320,200)];
[scroll setContentSize:CGSizeMake(640, 200)];
Or if you want to animate the view you can use affine transforms.
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:1];
someview.transform=CGAffineTransformMakeTranslation(-100, 0);
[UIView commitAnimations];
