iOS - Toolbar


Use of Toolbar

If we want to manipulate something based on our current view we can use toolbar.

Example would be the email app with an inbox item having options to delete, make favourite, reply and so on. It is shown below.

Add a Custom Method addToolbar

    UIBarButtonItem *spaceItem = [[UIBarButtonItem alloc] 
    target:nil action:nil];
    UIBarButtonItem *customItem1 = [[UIBarButtonItem alloc]
    initWithTitle:@"Tool1" style:UIBarButtonItemStyleBordered 
    target:self action:@selector(toolBarItem1:)];
    UIBarButtonItem *customItem2 = [[UIBarButtonItem alloc]
    initWithTitle:@"Tool2" style:UIBarButtonItemStyleDone 
    target:self action:@selector(toolBarItem2:)];
    NSArray *toolbarItems = [NSArray arrayWithObjects: 
    customItem1,spaceItem, customItem2, nil];
    UIToolbar *toolbar = [[UIToolbar alloc]initWithFrame:
    CGRectMake(0, 366+54, 320, 50)];
    [toolbar setBarStyle:UIBarStyleBlackOpaque];
    [self.view addSubview:toolbar];
    [toolbar setItems:toolbarItems];

For knowing the action performed, we add a UILabel in our ViewController.xib and create an IBoutlet for the UILabel and name it as label.

We also need to add two methods in order to execute actions for toolbar items as shown below.

    [label setText:@"Tool 1 Selected"];

    [label setText:@"Tool 2 Selected"];    

Update viewDidLoad in ViewController.m as follows −

- (void)viewDidLoad
    [super viewDidLoad];
    // The method hideStatusbar called after 2 seconds
    [self addToolbar];    
    // Do any additional setup after loading the view, typically from a nib.


When we run the application, we'll get the following output −
