[英]Delegate declared in UIView subclass won't work in UIViewController?
[英]UIView animation doesn't work for UIViewController subclass
我嘗試向當前視圖添加一個子視圖(這是UIViewController的子類,由幾個UIButton和UILabel組成),但是動畫不起作用,該子視圖只是不帶動畫而出現。
代碼是:
[UIView beginAnimations:nil context:nil];
[UIView setAnimaitonCurve:UIViewAnimationCurveLinear];
[UIView setAnimationDuration:0.5f];
[UIView setAnimationTransition:transition forView:thisPersonViewController.view cache:YES];
[self.view addSubView:thisPersonViewController.view];
[UIView commitAnimations];
它只是不工作,但如果我改變forView參數從子視圖 (thisPersonViewController.view),以self.view,對self.view沒有動畫,這是古玩。
我的xcode版本是4.2,SDK版本是5.0,任何提供解決方案的人都可以使用!
===========下面的代碼很不錯================
CATransition *trans = [CATransition animation];
[trans setDuration:0.4f];
[trans setType:kCATransitionReveal];
[trans setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
[[thisPersonViewController.view layer]addAnimation:trans forKey:kCATransitionReveal];
[self.view addSubview:thisPersonViewController.view];
另一個煩人的問題是,如果我將CATransition類型更改為kCATransitionFromBottom或其他原因,動畫將不再起作用!
將thisPersonViewController.view作為子視圖添加,其位置在屏幕之外。 (即,幀x / y坐標位於屏幕底部的右側。)
做這個:
[UIView animateWithDuration:0.5f delay:0.0f options:UIViewAnimationCurveLinear animations:^(void)
{
// Move it to wherever you want to have it.
thisPersonViewController.view.frame = CGRectMake(0.0f, 0.0f, thisPersonViewController.view.frame.size.width, thisPersonViewController.view.frame.size.height);
}
completion:^(BOOL finished)
{
// Do something when it completes the animation if you so desire.
}];
