In ios sdk, some time we need to
insert/delete tab bar item run time. So In this case, we can add and remove tab
bar items by following below code.
// Remove and Add Tab bar item
from tabbar controller at run time:
-(IBAction)
RemoveTab:(id)sender
{
UIViewController *itemToRemove = nil;
NSMutableArray *newItems = [NSMutableArray arrayWithArray:self.tabBarController.viewControllers];
for (UIViewController
*aView in newItems)
{
if
([[[aView class] description]
isEqualToString:@"FirstViewController"])
{
//store this item
to remove later
itemToRemove = aView;
}
}
if (itemToRemove)
{
[newItems removeObject:itemToRemove];
}
}
// Add Tab bar item in tabbar controller at run
time:
-(IBAction)
AddTab:(id)sender
{
NSMutableArray
*newItems = [NSMutableArray arrayWithArray:self.tabBarController.viewControllers];
//Add New ViewController
UITabBarItem
*obj = [[FirstViewController alloc] init];
// or use below
//UITabBarItem *obj = [[FirstViewController alloc]
initWithNibName:@"FirstViewController" bundle:nil];
[newItems addObject:obj];
obj.title = @"First";
[obj
release];
[self.tabBarController
setViewControllers:newItems];
}
This code has worked perfectly
for me, but if you have any problem inform me.
Or get any new or more efficient
way.
Thanks……………..
