change backbutton with custom image and textcolor - iphone

Question

I want to change the backbutton appearance for my backbutton in my navigation bar. For that I have this piece of code.
UIImage *backButtonImage = [UIImage imageNamed:#"backbutton.png"];
UIButton *backbutton = [UIButton buttonWithType:UIButtonTypeCustom];
backbutton.backgroundColor = [UIColor colorWithPatternImage:backButtonImage];
backbutton.titleLabel.text = #"back";
backbutton.titleLabel.textColor= [UIColor colorWithRed:50/255.0
green:158/255.0
blue:218/255.0
alpha:1.0];
backbutton.frame = CGRectMake(0, 0, backButtonImage.size.width, backButtonImage.size.height);
UIBarButtonItem * back = [[UIBarButtonItem alloc] initWithCustomView:backbutton];
[backbutton addTarget:self action:#selector(back_Clicked) forControlEvents:UIControlEventTouchUpInside];
self.navigationItem.leftBarButtonItem = back;
But still I get the standard back button. Any help ?

Answer 1

Put your code to customize back button before pushing that viewController to the stack. And set BackBarButtonItem , not leftBarButtonItem.
UIImage *image = [UIImage imageNamed:#"backbutton.png"];
UIButton *backbutton = [UIButton buttonWithType:UIButtonTypeCustom];
backbutton.bounds = CGRectMake( 0, 0, image.size.width, image.size.height );
[backbutton setImage:image forState:UIControlStateNormal];
backbutton.titleLabel.textColor = [UIColor blueColor];
UIBarButtonItem *back = [[UIBarButtonItem alloc] initWithCustomView:backbutton];
[[self navigationItem] setBackBarButtonItem: back];
[self.navigationController pushViewController:yourViewControllerObject animated:YES];

Answer 2

using bellow code for your requirement..
- (void)viewDidLoad
{
///write your code
UIImage *backButtonImage = [UIImage imageNamed:#"backbutton.png"];
UIButton *backbutton = [UIButton buttonWithType:UIButtonTypeCustom];
//[backbutton setImage:backButtonImage forState:UIControlStateNormal];//this line for set only image on button
[backbutton setBackgroundImage:backButtonImage forState:UIControlStateNormal];
[backbutton setTitle:#"Back" forState:UIControlStateNormal];
backbutton.frame = CGRectMake(0, 0, backButtonImage.size.width, backButtonImage.size.height);
UIBarButtonItem * back = [[UIBarButtonItem alloc] initWithCustomView:backbutton];
[backbutton addTarget:self action:#selector(back_Clicked) forControlEvents:UIControlEventTouchUpInside];
self.navigationItem.leftBarButtonItem = back;
}
when back button clicked bellow method call and you will go to previous viewcontroller
-(void)back_Clicked{
[self.navigationController popViewControllerAnimated:YES];
}

Answer 3

Use
self.navigationItem.leftBarButtonItem = back;
Instead of
self.navigationController.navigationItem.leftBarButtonItem = back;

[self.navigationItem setLeftBarButtonItem:[[UIBarButtonItem alloc] initWithCustomView:[self buttonWithImage:#"backButton" heighlightImageName:#"backButton" buttonFrame:CGRectMake(2, 1, 30, 30) selectorName:#selector(buttonBackClicked:) target:self]]];
- (UIButton*)buttonWithImage:(NSString*)normalImageName heighlightImageName:(NSString*)heighlightImageName buttonFrame:(CGRect)buttonFrame selectorName:(SEL)selectorName target:(id)target
{
UIButton *tempButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[tempButton setFrame:buttonFrame];
[tempButton addTarget:target action:selectorName forControlEvents:UIControlEventTouchUpInside];
[tempButton setImage:[self getImageFromResource:normalImageName] forState:UIControlStateNormal];
[tempButton setImage:[self getImageFromResource:heighlightImageName] forState:UIControlStateHighlighted];
return tempButton;
}
- (UIImage*)getImageFromResource:(NSString*)imageName
{
return [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:imageName ofType:#"png"]];
}
