viewDidLoad :
topBarMenu = [[TopBarMenu alloc] initWithFrame:CGRectMake(0, 64, 1024, 0)];
[self.view addSubview:topBarMenu];
topBarMenu.clipsToBounds = YES;
- (void)menuButton_TouchUpInside:(TopBarIcon *)sender
{
isTopBarMenuShown = !isTopBarMenuShown;
if (isTopBarMenuShown) {
[UIView animateWithDuration:1.5 animations:^{
topBarMenu.frame = CGRectMake(0, 64, 1024, 600);
}];
}else {
[UIView animateWithDuration:1.5 animations:^{
topBarMenu.frame = CGRectMake(0, 64, 1024, 0);
}];
}
}
在我的代码中,我希望动画显示和隐藏我的菜单。显示非常阶梯,看起来不好看。隐藏在没有任何动画的情况下立即移除屏幕。如何解决这个问题?

试试这个
if (sideView.frame.origin.x >= 0 )
{
[UIView animateKeyframesWithDuration:0.5 delay:0 options:UIViewKeyframeAnimationOptionBeginFromCurrentState animations:^{
sideView.frame=CGRectMake(-400, 45, CGRectGetWidth(sideView.frame), CGRectGetHeight(sideView.frame));
} completion:^(BOOL finished) {
}];
}
else
{
[UIView animateKeyframesWithDuration:0.5 delay:0 options:UIViewKeyframeAnimationOptionBeginFromCurrentState animations:^{
sideView.frame=CGRectMake(0, 45, CGRectGetWidth(sideView.frame), CGRectGetHeight(sideView.frame));
} completion:^(BOOL finished)
{
}];
}

使用Autolayout和Animation时,您需要设置常量。因此,在开始动画之前设置常量。因此,创建y位置约束的出口。
topbaryposition.constant=0; (IBOutlet of Top position (Y postion of Topbar))
- (void)menuButton_TouchUpInside:(TopBarIcon *)sender
{
isTopBarMenuShown = !isTopBarMenuShown;
if (isTopBarMenuShown) {
[UIView animateWithDuration:1.5 animations:^{
topBarMenu.frame = CGRectMake(0, 64, 1024, 600);
}];
}else {
[UIView animateWithDuration:1.5 animations:^{
topBarMenu.frame = CGRectMake(0, 64, 1024, 0);
}];
}
}

我找到了你的问题。
当您隐藏顶部栏时,您的问题是在其他地方继续使用框架。您只将高度设置为 0 ,但您还需要将 y positioan设置为0 。
类似的东西,
topBarMenu.frame = CGRectMake(0, 0, 1024, 0);
- (void)menuButton_TouchUpInside:(TopBarIcon *)sender
{
isTopBarMenuShown = !isTopBarMenuShown;
if (isTopBarMenuShown) {
[UIView animateWithDuration:1.5 animations:^{
topBarMenu.frame = CGRectMake(0, 64, 1024, 600);
}];
}else {
[UIView animateWithDuration:1.5 animations:^{
topBarMenu.frame = CGRectMake(0, 0, 1024, 0);
}];
}
