に取り組んでいない私は私のFYImageSequence.m file.Iでこれらの2つの機能を持っていますが、UIImageViewTouchesbeganとtouchesmoved機能UIImageView
@interface FVImageSequence : UIImageView
からクラスを継承し、私はstoryboard.Butの私のUIImageViewにこれを接続することができましたどのように下の機能を働かせるか。どのような接続が必要ですか。
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
if(increment == 0)
increment = 1;
[super touchesBegan:touches withEvent:event];
UITouch *touch = [[event allTouches] anyObject];
CGPoint touchLocation = [touch locationInView:self];
previous = touchLocation.x;
}
-(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {
[super touchesMoved:touches withEvent:event];
UITouch *touch = [[event allTouches] anyObject];
CGPoint touchLocation = [touch locationInView:self];
int location = touchLocation.x;
if(location < previous)
current += increment;
else
current -= increment;
previous = location;
if(current > numberOfImages)
current = 0;
if(current < 0)
current = numberOfImages;
NSString *path = [NSString stringWithFormat:@"%@%d", prefix, current];
NSLog(@"%@", path);
path = [[NSBundle mainBundle] pathForResource:path ofType:extension];
UIImage *img = [[UIImage alloc] initWithContentsOfFile:path];
[self setImage:img];
}
