当我旋转 iPad 时,所有动画组件(例如视图/按钮)将回到它们最初加载时的原始位置。有什么办法可以防止这种情况发生吗?
这是我单击按钮时为对象设置动画的方式,例如
- (IBAction)button1Pressed:(id)sender{
[UIView animateWithDuration:ANIMATION_SPEED
delay:0.0
options:UIViewAnimationOptionBeginFromCurrentState
animations:(void (^)(void)) ^{
self.view.userInteractionEnabled = NO;
_button1.center = CGPointMake(73.01, 419.0);
_button2.center = CGPointMake(750.0, 419.0);
_button3.center = CGPointMake(850.0, 419.0);
_button4.center = CGPointMake(950.0, 419.0);
CGRect theFrame = _loginView.frame;
theFrame.size.width = 576.f;
_View1.frame = theFrame;
_View2.frame = CGRectMake(_button2.center.x + 44.0, _button2.center.y / 2 - 89.0, 0.0, 597.0);
_View3.frame = CGRectMake(_button3.center.x + 44.0, _button3.center.y / 2 - 89.0, 0.0, 597.0);
_4View.frame = CGRectMake(_button4.center.x + 44.0, _button4.center.y / 2 - 89.0, 0.0, 597.0);
}
completion:^(BOOL finished){
self.view.userInteractionEnabled = YES;
}];
}
我还是很新,所以所有的细节都将不胜感激:)
