Voici le deal: Je code un UIImageView dans viewDidLoad et je veux qu'il descende avec ma fonction buttonPressed ** sans créer d'autre sous-vue comme je le fais.Comment déplacer UIImageView?
Indique le code.
- (void) {viewDidLoad
[super viewDidLoad];
banetteImage = [UIImage imageNamed: @ "myBanette.png"];
UIImageView *banetteView = [[UIImageView alloc] initWithImage:banetteImage];
banetteView.frame = CGRectMake(100, -740, 568, 790);
banetteView.opaque = NO;
[NSTimer scheduledTimerWithTimeInterval: 2,5 cible: self sélecteur: @selector (ButtonPressed:) userInfo: néant répétitions: NO];
[self.view addSubview:banetteView];
}
- (void) ButtonPressed {
double speed = 1/round(random() % 100) + 1.0;
[UIView beginAnimations:nil context:banetteView];
[UIView setAnimationDuration: 2*speed ];
banetteView.frame = CGRectMake(100, -2, 568, 790);
banetteView.opaque = NO;
UIImageView *banetteView = [[UIImageView alloc] initWithImage:banetteImage];
banetteView2.frame = CGRectMake(100, -740, 568, 790);
banetteView.opaque = NO;
banetteView.hidden = YES;
[self.view addSubview:banetteView];
// set a stop callback so we can cleanup the banette when it reaches the
// end of its animation
[UIView setAnimationDidStopSelector:@selector(onAnimationComplete:finished:context:)];
[UIView setAnimationDelegate:self];
[UIView commitAnimations];
}
- (void) onAnimationComplete: (NSString *) animationID terminé: (NSNumber *) a terminé son contexte: (vide *) contexte {
UIImageView *banetteView = context;
double speed = 1/round(random() % 100) + 1.0;
banetteView.frame = CGRectMake(100, -2, 568, 790);
banetteView2.opaque = NO;
[self.view addSubview:banetteView2];
[UIView beginAnimations:nil context:banetteView];
[UIView setAnimationDuration: 2*speed ];
[banetteView release];
}
