UIImage をいくつかの UIButtons の 1 つにドラッグし、ドラッグ先のボタンに基づいて再配置したいと考えています。
私が遭遇した問題は、UITouch がタッチを開始したビューのみを記録することです。タッチが終了したビューにアクセスしたいと思います。これどうやってするの?
コード:
-(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
UITouch *touch = [touches anyObject];
CGPoint location = [touch locationInView:self.view];
dealerBtnOrigin = [touch locationInView:self.view];
//NSLog(@"%u %u",touch.view.tag, ((UIView *)[dealerBtns objectAtIndex:[table getButtonSeat]]).tag);
//CHECK TO SEE WHICH BUTTON WAS TOUCHED
if (touch.view == ((UIView *)[dealerBtns objectAtIndex:[table getButtonSeat]]))
{
((UIView *)[dealerBtns objectAtIndex:[table getButtonSeat]]).center = location;
}
}
-(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
{
UITouch *touch = [touches anyObject];
CGPoint location = [touch locationInView:self.view];
if (touch.view == ((UIView *)[dealerBtns objectAtIndex:[table getButtonSeat]]))
{
((UIView *)[dealerBtns objectAtIndex:[table getButtonSeat]]).center = location;
}
}
-(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
UITouch *touch = [touches anyObject];
CGPoint location = [touch locationInView:self.view];
UIView *endView = [self.view hitTest:location withEvent:nil];
if (touch.view == ((UIView *)[dealerBtns objectAtIndex:[table getButtonSeat]]))
{
NSLog(@"%u %u",endView.tag, touch.view.tag);
if([buttons containsObject:(UIButton *)endView])
{
[[dealerBtns objectAtIndex:[table getButtonSeat]] setHidden:YES];
[table passButton:touch.view.tag];
[[dealerBtns objectAtIndex: touch.view.tag] setHidden:NO];
}
((UIView *)[dealerBtns objectAtIndex:[table getButtonSeat]]).center = dealerBtnOrigin;
}
}
