How do I get the backBarButtonItem width?
I am trying to get the backBarButtonItem width:
UIBarButtonItem *leftBtn = self.navigationItem.backBarButtonItem;
UIView *view = [leftBtn valueForKey:@"view"];
CGFloat width;
if(view){
width=view.frame.size.width;
}
NSLog(@"width %f", width);
but in the console: width 0.000000
Any ideas what I might be doing wrong? With self.navigationItem.rightBarButtonItem
it works.

UIButton *addButton = [UIButton buttonWithType:UIButtonTypeCustom];
CALayer *btnLayer = [addButton layer];
[btnLayer setMasksToBounds:YES];
[btnLayer setCornerRadius:1.0f];
[addButton setFrame:CGRectMake(0, 0, 45, 30)];
[addButton setBackgroundColor:[UIColor orangeColor]];
[addButton setTitle:@"Title" forState:UIControlStateNormal];
addButton.titleLabel.font = [UIFont systemFontOfSize:14.0];
[addButton addTarget:self action:@selector(Onclickevent:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *barButtonItem = [[UIBarButtonItem alloc] initWithCustomView:addButton];
[self.navigationItem setRightBarButtonItem:barButtonItem];
