How to add four or more navigation bar buttons in your iOS App XCode Project

I assume that you have added navigation controller through Editor > Embed In > Navigation Controller in xib (or formally nib) file in your XCode Projects’ Storyboard

 
Problem:

 
Then for example you have added Action button for Tweet Sheet at Left & Menu button at right & Title button in middle.

 
But this three items doesn’t allowing you to add additional button at second left position.

Through this additional functionality you can enrich your app’s usp (unique selling point) or usability.

 
Reason:

 
It turns out, this is a limitation of Interface Builder. It will only let you configure a single left and right bar button item in a navigation bar. Not to worry though, you can still configure your remaining items in code. For example,

 
Solution:

 
Add following code in viewDidLoad function in your View Controller’s Header file i.e .h file

 

UIBarButtonItem *email = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCompose target:self action:@selector(someAction)];
    self.navigationItem.leftBarButtonItems = [self.navigationItem.leftBarButtonItems arrayByAddingObject:email];

 
So now your viewDidLoad function will look like this:

 

- (void)viewDidLoad
{
    [super viewDidLoad];
    //Add a compose button alongside the existing left bar button item from the storyboard.
    UIBarButtonItem *email = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCompose target:self action:@selector(someAction)];
    self.navigationItem.leftBarButtonItems = [self.navigationItem.leftBarButtonItems arrayByAddingObject:email];
}

 
Now you can write method for your added button like this:

 

- (IBAction)someAction
{
    // Your code here...
}
