如何隐藏uitabbarcontroller
提问于 2011-03-11 19:24:55
我对UITabBarController有个问题。在我的应用程序中，我想隐藏它，但不使用hidesBottomBarWhenPushed，因为我想隐藏它，而不是在推送它时隐藏它。例如，当我在应用程序中按下隐藏按钮时，我想隐藏它。
我在谷歌上读了很多文章，但我找不到我该怎么做。

修改了Setomidor的答案，以便同时适用于横向、纵向和iPad ( 320和480值仅适用于iPhone)。
- (void) hideTabBar:(UITabBarController *) tabbarcontroller
{
CGRect screenRect = [[UIScreen mainScreen] bounds];
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.5];
float fHeight = screenRect.size.height;
if( UIDeviceOrientationIsLandscape([UIApplication sharedApplication].statusBarOrientation) )
{
fHeight = screenRect.size.width;
}
for(UIView *view in tabbarcontroller.view.subviews)
{
if([view isKindOfClass:[UITabBar class]])
{
[view setFrame:CGRectMake(view.frame.origin.x, fHeight, view.frame.size.width, view.frame.size.height)];
}
else
{
[view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, fHeight)];
view.backgroundColor = [UIColor blackColor];
}
}
[UIView commitAnimations];
}
- (void) showTabBar:(UITabBarController *) tabbarcontroller
{
CGRect screenRect = [[UIScreen mainScreen] bounds];
float fHeight = screenRect.size.height - tabbarcontroller.tabBar.frame.size.height;
if( UIDeviceOrientationIsLandscape([UIApplication sharedApplication].statusBarOrientation) )
{
fHeight = screenRect.size.width - tabbarcontroller.tabBar.frame.size.height;
}
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.5];
for(UIView *view in tabbarcontroller.view.subviews)
{
if([view isKindOfClass:[UITabBar class]])
{
[view setFrame:CGRectMake(view.frame.origin.x, fHeight, view.frame.size.width, view.frame.size.height)];
}
else
{
[view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, fHeight)];
}
}
[UIView commitAnimations];
}我还修改了代码，以处理UIDevice方向更改在iOS 6中引入的更改，并确保即使在设备仰卧时也能正常工作。

Saurabh上面的答案可以扩展到也适用于横向：
+ (void) hideTabBar:(UITabBarController *) tabbarcontroller {
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.5];
//Support for landscape views
int orientation = [[UIDevice currentDevice] orientation];
int x_pos = 480;
if (orientation == UIInterfaceOrientationLandscapeLeft || orientation == UIInterfaceOrientationLandscapeRight) {
x_pos = 320;
}
for(UIView *view in tabbarcontroller.view.subviews)
{
if([view isKindOfClass:[UITabBar class]])
{
[view setFrame:CGRectMake(view.frame.origin.x, x_pos, view.frame.size.width, view.frame.size.height)];
}
else
{
[view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, x_pos)];
}
}
[UIView commitAnimations];
}`
showTabBar()对应的x_pos编号是431和271。
