Detecting UITableView scrolling
- by Xeph
Hi
I've subclassed UITableView (as KRTableView) and implemented the four touch-based methods (touchesBegan, touchesEnded, touchesMoved, and touchesCancelled) so that I can detect when a touch-based event is being handled on a UITableView. Essentially what I need to detect is when the UITableView is scrolling up or down.
However, subclassing UITableView and creating the above methods only detects when scrolling or finger movement is occuring within a UITableViewCell, not on the entire UITableView.
As soon as my finger is moved onto the next cell, the touch events don't do anything.
This is how I'm subclassing UITableView:
#import "KRTableView.h"
@implementation KRTableView
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
[super touchesBegan:touches withEvent:event];
NSLog(@"touches began...");
}
- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {
[super touchesMoved:touches withEvent:event];
NSLog(@"touchesMoved occured");
}
- (void)touchesCancelled:(NSSet*)touches withEvent:(UIEvent *)event {
[super touchesCancelled:touches withEvent:event];
NSLog(@"touchesCancelled occured");
}
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
[super touchesEnded:touches withEvent:event];
NSLog(@"A tap was detected on KRTableView");
}
@end
How can I detect when the UITableView is scrolling up or down?
