您是否为工具栏的外观设置了动画 - 我无法让它动画
这个:
[self.navigationController setToolbarHidden:NO animated:YES];
或这个:
[UIView animateWithDuration:2.0
animations:^{
[self.navigationController setToolbarHidden:NO
animated:YES];
}
completion:^(BOOL finished){
// whatever
}];
}
同时
- (void)viewDidAppear:(BOOL)animated{
- (void)viewWillAppear:(BOOL)animated{
}
