Sto avendo queste 2 funzioni nella mia FYImageSequence.m file.I ereditato la classe da UIImageViewtouchesBegan e touchesMoved funzioni non lavorare su UIImageView
@interface FVImageSequence : UIImageView
mi è stato in grado di collegare questo al mio UIImageView in storyboard.But come rendere le funzioni sotto funzionanti. Ci sono delle connessioni che dovrebbero essere fatte.
-(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];
}
