如何在iPhone应用程序中将导航控制器的后退按钮对齐到其左角

Question

I have customized my navigation controller back button by adding image to it,but still I couldn't get back button in to navigationbar's left corner.I want to avoid the gap or the space between navigation bar's left margin and the backbutton. Thanks for the help.

Here is the code you can use

 UIButton* backButton= [UIButton buttonWithType:UIButtonTypeCustom];
//here in below you just need to pass the point where you want to place your button.

As you said you need space between navigation bar's left margin and the back button.

[backButton setFrame:CGRectMake(xOrigin, yOrigin, width, height)];
[backButton setImage:[UIImage imageNamed:@"imageName.png"] forState:UIControlStateNormal];
UIBarButtonItem * leftBarButton =[[UIBarButtonItem alloc] initWithCustomView:backButton];
self.navigationItem.leftBarButtonItem= leftBarButton;

I hope it may help you.
