thank you Alan. your solution works

I only added

-(BOOL)delaysContentTouches(Uiview *)view {
if ([view isKindOfClass:[UIPickerView class]] || [@"UIPickerTable" isEqualToString:[[view class] description]] ) {
return NO;
}
return [super touchesShouldCancelInContentView:view];
}

and modefied touchesShouldBegin to be like this

- (BOOL)touchesShouldBegin:(NSSet *)touches withEvent:(UIEvent *)event inContentView:(UIView *)view {
if ([view isKindOfClass:[UIPickerView class]] || [@"UIPickerTable" isEqualToString:[[view class] description]] ) {
//|| [view isKindOfClass:[UIPicker class]]
return YES;
}
return [super touchesShouldBegin:touches withEvent:event inContentView:self]; // self instead of view
}

You have to set both:

[myView setDelaysContentTouches:NO];
[myView setCanCancelContentTouches:NO];

I created a UIScrollView subclass and overrode the following methods

@interface PickerAwareUIScrollView : UIScrollView {
}
- (BOOL)touchesShouldBegin:(NSSet *)touches withEvent:(UIEvent *)event inContentView:(UIView *)view;
- (BOOL)touchesShouldCancelInContentView:(UIView *)view;

- (BOOL)touchesShouldCancelInContentView:(UIView *)view {
if ([view isKindOfClass:[UIPickerView class]] || [@"UIPickerTable" isEqualToString:[[view class] description]] ) {
return NO;
}
return [super touchesShouldCancelInContentView:view];
}

In my case - using the above code simply disabled the scrolling of the scrollView - unfortunately I do need to be able to scroll, except when using the picker. Any ideas?

You also have to set: @property(nonatomic) BOOL delaysContentTouches to no

I got mine to work by adding only the line of code he mentioned. Seems silly to mention this but: in order to get the picker control to move you must keep you finger on the picker control “a little longer” so the picker control gets the action and not the scrollview. From what I’ve read the scrollview works with a timer and if there is no swipe/flick by the time the timer fires the action is then passed to the underlying control.

Hope this helps.
