_cardView =[card initCard];
[self.view addSubview:_cardView];

我有一个视图,使其看起来像是从一个点(类似于正在打开的应用程序的动画)展开看起来。该视图从[card initCard]返回,卡片是自定义类,并分配给_cardView。使用CGAffineTransformScale我首先减小比例,然后动画增加比例。这对于显示的第一张卡完全适用。但是,如果将_cardView设置为nil并将新卡分配给它,则相同的转换和动画代码会生成错误的动画,这会使视图在缩小之前增加比例。我认为问题在于使比例为0.1,0.1,但我无法解决这个问题。转换后的重置比例
设置为nil:
else if (sender.state == UIGestureRecognizerStateEnded || sender.state == UIGestureRecognizerStateCancelled || sender.state == UIGestureRecognizerStateFailed)
{
if(sender.view.center.x>0){
[UIView animateWithDuration:0.2 animations:^{
CGRect rect=[sender.view frame];
rect.origin.x=([self.view frame].size.width/2)-129.5;
[sender.view setFrame:rect];
sender.view.alpha = 0.8;
}];
}else{
[UIView animateWithDuration:0.5 animations:^{
_protoypeView.alpha=0.0;
_protoypeView=nil;
_cardView=nil;
[self nextCard];
}];
}
}
和功能nextCard:
-(void)nextCard{
if(cardNumber>[questionArray count]-1){
NSLog(@"Out of cards");
}else{
QuestionCard *card=[[QuestionCard alloc]init];
NSArray* array =[[NSArray alloc]initWithArray:questionArray[cardNumber]];
card.questionString=array[3];
card.whenPosted=array[0];
card.isAnon=array[2];
card.user=array[1];
card.replies=array[4];
card.profileImg=array[5];
_cardView =[card initCard];
[self.view addSubview:_cardView];
_cardView.alpha=0.0;
_cardView.transform=CGAffineTransformScale(CGAffineTransformIdentity, -1, -1);
_cardView.transform=CGAffineTransformIdentity;
[UIView animateWithDuration:1 animations:^{
_cardView.alpha=0.7;
}];
UIPanGestureRecognizer * pan1 = [[UIPanGestureRecognizer alloc]initWithTarget:self action:@selector(handlePanImage:)];
pan1.minimumNumberOfTouches = 1;
[_cardView addGestureRecognizer:pan1];
yOfView=[_cardView frame].origin.y+([_cardView frame].size.height/2);
cardNumber++;
}
}
CGAffineTransform的第一种情况(查询成功后,解析数据库):
[UIView animateWithDuration:0.5 animations:^{
_protoypeView.alpha=0.0;
}completion:^(BOOL finished){
QuestionCard *card=[[QuestionCard alloc]init];
NSArray* array =[[NSArray alloc]initWithArray:questionArray[cardNumber]];
card.questionString=array[3];
card.whenPosted=array[0];
card.isAnon=array[2];
card.user=array[1];
card.replies=array[4];
card.profileImg=array[5];
_cardView =[card initCard];
[self.view addSubview:_cardView];
_cardView.transform=CGAffineTransformScale(CGAffineTransformIdentity, 0.0, 0.0);
[UIView animateWithDuration:0.3
animations:^{
_cardView.transform=CGAffineTransformIdentity;
}];
UIPanGestureRecognizer * pan1 = [[UIPanGestureRecognizer alloc]initWithTarget:self action:@selector(handlePanImage:)];
pan1.minimumNumberOfTouches = 1;
[_cardView addGestureRecognizer:pan1];
yOfView=[_cardView frame].origin.y+([_cardView frame].size.height/2);
cardNumber++;
}];

这里有很多事情需要改变;但让我们继续关注你的问题:你在哪里放置第一块代码?它不在您刚刚添加的任何代码中。 – Unheilig 2014-12-06 17:41:26
