I'm having trouble creating a custom navigation bar like Uber app .

I set the background image of the button:
UIImage *button44 = [[UIImage imageNamed:@"navButtonAdd"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 0, 0, 0)]; [[UIBarButtonItem appearance] setBackgroundImage:button44 forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
But if I delete the text from the button on the xcode interface, it will also disappear, and an inscription will appear on the right, which will again repeat my image.

Does anyone know how I can fix this?
This is the image I'm trying to use as a button

Thank you in advance
