- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
[self.navigationController setNavigationBarHidden:YES animated:YES];
}
隐藏tabbar可以这样：
- (void) hideTabBar:(BOOL) hidden {
[UIView
beginAnimations:nil
context:NULL];
[UIView
setAnimationDuration:0.7];
for(UIView *view
in self.tabBarController.view.subviews)
{
if([view isKindOfClass:[UITabBar
class]])
{
if (hidden) {
[view setFrame:CGRectMake(view.frame.origin.x,
480, view.frame.size.width, view.frame.size.height)];
} else {
[view setFrame:CGRectMake(view.frame.origin.x,
480-49, view.frame.size.width, view.frame.size.height)];
}
}
else
{
if (hidden) {
[view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y,
view.frame.size.width,
480)];
} else {
[view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y,
view.frame.size.width,
480-49)];
}
}
}
[UIView
commitAnimations];
}
