How to hide 'Back' button on navigation bar on iPhone?
Objective-C:self.navigationItem.hidesBackButton = YES;
Swift:navigationItem.hidesBackButton = true
The best way is to combine these, so it will hide the back button even if you set it up manually :
self.navigationItem.leftBarButtonItem=nil;self.navigationItem.hidesBackButton=YES;
hide back button with bellow code...
[self.navigationItem setHidesBackButton:YES animated:YES];
or
[self.navigationItem setHidesBackButton:YES];
Also if you have custom UINavigationBar
then try bellow code
self.navigationItem.leftBarButtonItem = nil;
