Question

Its a very basic question – but i could not find the answer to it anywhere.
I would like a back button like the default one that shows up in a navigation bar, but with a image in the background.
Even with customization, how to calculate the size/length of the button as per the title?
Thanks a ton for the help,in advance!

UPDATE:

Thanks guys! but the answer that i finally implemented was this:

@implementation UINavigationBar (UINavigationBarCategory)

-(void)drawRect:(CGRect)rect

{

UIColor *color = [UIColor colorWithRed:(13.0/255.0) green:(183.0/255.0) blue:(255.0/255.0) alpha:1.0];

// use a custom color for the back button which i got using the digital color meter on my nav bar image 😛

CGContextRef context = UIGraphicsGetCurrentContext();

CGContextSetFillColor(context, CGColorGetComponents( [color CGColor]));

CGContextFillRect(context, rect);
self.tintColor = color;
// use a custom background image for my navigation bar

UIImage *img = [UIImage imageNamed: Navigation_img];

[img drawInRect:CGRectMake(0,0,img.size.width,img.size.height)];

}//worked satisfactorily for me

@end

Answer 1

• Create a UIButton using your own UIImage to mimic the shape you want.
• The UIImage must be a stretchable type, that is, you would set the leftCapWidth to be the size of your back arrow
• Set the UIButton‘s title to whatever you like
• Create a new UIBarButtonItem using your new button as a custom view
• Set this to your navigationItems leftBarButtonItem property.

The button will automatically size to fit your title.
