我在这里找不到答案,也没有看到重复的问题.
我的代码很简单给定3个UIView,parent,from和to,从父中删除并添加子视图.添加动画,但只是doodads.
现在,问题是当我这样做,然后被抵消.就好像被推倒了
我甚至添加To.frame = ParentView.frame;以确保它有效.没有
我该怎么做？
+ (void) AnimateSwitchingWithParent: (UIView *) ParentView From: (UIView *) From To: (UIView* ) To
{
/*[UIView beginAnimations:@"View Flip" context:nil];
[UIView setAnimationDuration:1.25];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationTransition: UIViewAnimationTransitionFlipFromRight forView:ParentView cache:YES];*/
[From removeFromSuperview];
[ParentView addSubview:To];
To.frame=ParentView.frame; //If I don't do this,the subview is still off by around 20 points
NSLog(@"To.bounds: %@",NSStringFromCGRect(To.bounds));
NSLog(@"From.bounds.: %@",NSStringFromCGRect(From.bounds));
NSLog(@"ParentView.bounds: %@",NSStringFromCGRect(ParentView.bounds));
//JA_DUMP (To.bounds);
//JA_DUMP (To.bounds);
/*[UIView commitAnimations];*/
}
我已经弄清楚了解决方案.结束To的框架
To.frames：{{0,0},{320,372}}
但是,如果我删除To.frame = ParentView.frame框架也是
{{0,20},460}}
我想知道为什么？ 20点似乎是状态栏的距离.我们在哪里可以在InterfaceBuilder中设置该框架？
我在SimulatedMetric部分中将statusbar设置为none.
解决方法
似乎你误解了框架和边界,将你的代码修改为To.frame = ParentView.bounds;应该可以.
