What's the best way to add a view under UINavigationBar in iOS7

On ios7, a lot of apps (Apple Messages, Facebook Messenger, Calendar)have views appearing under the UINavigationBar, often with what seems to be standard animation. As it seems quite standard and looks a lot with a UIToolBar, I was looking for the standard way of implementing it but couldn't find anything.

Is there a better way to adding a UIToolBar to the UINavigationBar?

You should follow this simple approach.

  • Add a UIToolBar like this.

    UIBarButtonItem *flexiableItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil];
UIBarButtonItem *item1 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:nil];
UIBarButtonItem *item2 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAction target:self action:nil];

NSArray *items = [NSArray arrayWithObjects:item1, flexiableItem, item2, nil];
self.toolBar = [[UIToolbar alloc]initWithFrame:CGRectMake(0, -44, self.view.frame.size.width, 44)];
[self.toolBar setItems:items];
self.toolBar.tintColor = [UIColor whiteColor];
self.toolBar.barTintColor = [UIColor colorWithRed:0.6 green:0.1 blue:0.2 alpha:1];
[self.contentView addSubview:self.toolBar];

  • Add a Menu Button on Top navigation item

    self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Menu" style:UIBarButtonItemStyleBordered target:self action:@selector(toggleMenu:)];

  • Now Implement toggleMenu function. Add a BOOL variable to track the movement.

    if(!moved) {
[UIView animateWithDuration:0.5 animations:^{
    self.toolBar.alpha = 1;
    self.toolBar.frame = CGRectMake(0, 0, self.view.frame.size.width, 44);
}];
moved = YES;
}else {
[UIView animateWithDuration:0.5 animations:^{
    self.toolBar.alpha = 1;
    self.toolBar.frame = CGRectMake(0, -44, self.view.frame.size.width, 44);
}];
moved = NO;
}

  • Here is the attached video for this.

Hope that helps.
