UINavigationBar - Change Height / Add Big Button - ios

Question

I need to change the height of my Navigation Bar and add a custom Image button to the top left corner. I am part way there, but lost now on getting the custom Image button in the right position. Here is what I have:
To adjust the height I have created a UINavBar category with one method as follows:
#implementation UINavigationBar (myNavBar)
- (CGSize)sizeThatFits:(CGSize)size {
CGSize newSize = CGSizeMake(768,80);
return newSize;
}
#end
I have also created a UINavigationController subclass to modify the button. Here is the viewDidLoad from that class:
UIImage *navBackgroundImage = [UIImage imageNamed:#"bar"];
[[UINavigationBar appearance] setBackgroundImage:navBackgroundImage forBarMetrics:UIBarMetricsDefault];
// Change the appearance of back button
UIImage *backButtonImage = [[UIImage imageNamed:#"back_off"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 13, 0, 6)];
[[UIBarButtonItem appearance] setBackButtonBackgroundImage:backButtonImage forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
// Change the appearance of other navigation button
UIImage *barButtonImage = [[UIImage imageNamed:#"menu_off"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 6, 0, 6)];
[[UIBarButtonItem appearance] setBackgroundImage:barButtonImage forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
So far this solution resizes the top nav bar, but positions my button in a weird position. Here are what I want vs. what is happening:

Answer 1

I have a UIBarButtonItem Category that I use which has an offset property:
UIBarButtonItem+CustomImage.h
#interface UIBarButtonItem (CustomImage)
+ (UIBarButtonItem*)barItemWithImage:(UIImage*)image target:(id)target action:(SEL)action offset:(CGPoint)offset;
#end
UIBarButtonItem+CustomImage.m
#import "UIBarButtonItem+CustomImage.h"
#implementation UIBarButtonItem (CustomImage)
+ (UIBarButtonItem *)barItemWithImage:(UIImage *)image target:(id)target action:(SEL)action offset:(CGPoint)offset {
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setImage:image forState:UIControlStateNormal];
[button setFrame:CGRectMake(0.0, 0.0, image.size.width, image.size.height)];
[button addTarget:target action:action forControlEvents:UIControlEventTouchUpInside];
[button setBounds:CGRectOffset(button.bounds, 0.0, -10.0)];
UIView *container = [[UIView alloc] initWithFrame:button.frame];
[container setBounds:CGRectOffset(container.bounds, offset.x, offset.y)];
[container addSubview:button];
UIBarButtonItem *item = [[UIBarButtonItem alloc] initWithCustomView:container];
return item;
}
#end
Example Usage
#import "UIBarButtonItem+CustomImage.h"
UIBarButtonItem *settingsButton = [UIBarButtonItem barItemWithImage:settingsImage
target:self
action:#selector(revealSettings:)
offset:CGPointMake(0.0, 0.0)];
[self.navigationItem setLeftBarButtonItem:settingsButton];
