Programmatically add a back button to a UINavigationBar?

Question

I am using the following code to achieve a navigation bar in my app. (my app was crashing when I used a push segue so I need a modal segue meaning the nav bar is hidden after the modal segue is called)

UINavigationBar *navbar = [[UINavigationBar alloc]initWithFrame:CGRectMake(0, 0, 320, 50)];
//do something like background color, title, etc you self
[self.view addSubview:navbar];

Does any one know any methods I can use with the above code to achieve back button functionality in the nav bar??

Answer 1

Use below code to add back button on left side of navigation bar.Add UIBarButtonItem on Navigation bar.

UIBarButtonItem *backButton = [[UIBarButtonItem alloc] 
                           initWithTitle:@"Back"                                            
                           style:UIBarButtonItemStyleBordered 
                           target:self 
                           action:@selector(backBtnClicked:)];
self.navigationItem.leftBarButtonItem = backButton;
