Question

继承人：我在viewDidLoad中编写了一个UIImageView，我希望它能够使用我的fonction buttonPressed **向下移动而不像我那样创建其他子视图。

继承代码。

- （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 target：self selector：@selector（buttonPressed :) userInfo：nil repeats：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 finished：（NSNumber *）完成上下文：（void *）context {

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];

}
