是否可以隐藏带有动画的UIToolbar? [英] Is it possible to hide a UIToolbar with an animation?

问题描述

我知道此代码仅适用于UINavigationController.

I know this code is available to UINavigationController only.

[self.navigationController setNavigationBarHidden:YES animated:YES];

推荐答案

使用块的示例.这将在iPad屏幕顶部隐藏工具栏.

An example using blocks. This will hide a toolbar at the top of an iPad screen.

[UIView animateWithDuration:.7 
                 animations:^(void)
                 {
                     CGRect toolbarFrame = self.toolbar.frame;
                     toolbarFrame.origin.y = -44; // moves iPad Toolbar off screen
                     self.toolbar.frame = toolbarFrame;
                 } 
                 completion:^(BOOL finished)
                 {
                     self.toolbar.hidden = YES;
                 }];
