我正在使用UIView动画,其中第二个视图从底部出现并出现在视图的中心。但它不能在横向模式下工作,尽管我的应用程序支持横向模式,而且我实现了“willAnimateRotationToInterfaceOrientation:toInterfaceOrientation”方法。这里是我的代码:UIView动画不适用于横向模式
-(void) viewWillAppear:(BOOL)animated{
[super viewWillAppear:animated];
self.view.backgroundColor = [UIColor blackColor];
imageView= [[UIImageView alloc] initWithFrame:CGRectMake(0, 499, 320, 0)];
imageView.image = [UIImage imageNamed:@"trans.png"];
[imageView setClipsToBounds:YES];
[imageView setContentMode:UIViewContentModeBottom];
[self.view addSubview:imageView];
[UIView animateWithDuration:1.0f
delay:0.5f
options:UIViewAnimationOptionCurveEaseOut
animations:^(void) {
imageView.frame = CGRectMake(0, 92, 320, 320);
}
completion:NULL];
}
-(void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration{
CGRect screen = [[UIScreen mainScreen] bounds];
float pos_y, pos_x;
pos_y = UIDeviceOrientationIsLandscape([[UIDevice currentDevice] orientation]) ? screen.size.width/2 : screen.size.height/2;
pos_x = UIDeviceOrientationIsLandscape([[UIDevice currentDevice] orientation]) ? screen.size.height/2 : screen.size.width/2;
imageView.center = CGPointMake(pos_x, pos_y);
}
我猜I'm设置错了地方第二种观点的框架...
