UIBarButtonItem init with custom view selector not working properly - iphone

Question

I'm trying for hours to make a left button work properly and mimic a back button.
My code to create the button:
UIBarButtonItem *backButton = [self customBarButton:#"back_button" imageHiglighted:#"settings_button_highlighted" x:20 y:0 widthDivider:2.6 heightDivider:2.6];
backButton.target = self;
backButton.action = #selector(buttonPressed:);
self.navigationItem.leftBarButtonItem = backButton;
Here the method called to create custom button:
- (UIBarButtonItem *)customBarButton:(NSString *)imageDefault imageHiglighted:(NSString *)imageHighlighted x:(float)x y:(float)y widthDivider:(float)widthDivider heightDivider:(float)heightDivider {
UIImage *customImageDefault = [UIImage imageNamed:imageDefault];
UIImage *customImageHighlighted = [UIImage imageNamed:imageHighlighted];
CGRect frameCustomButton = CGRectMake(x, y, customImageDefault.size.width/widthDivider, customImageDefault.size.height/heightDivider);
UIButton *customButton = [[UIButton alloc] initWithFrame:frameCustomButton];
[customButton setBackgroundImage:customImageDefault forState:UIControlStateNormal];
[customButton setBackgroundImage:customImageHighlighted forState:UIControlStateHighlighted];
UIBarButtonItem *barCustomButton =[[UIBarButtonItem alloc] initWithCustomView:customButton];
return barCustomButton;
}
And the action:
-(void)buttonPressed:(id) sender{
NSLog(#"Entered");
SearchViewController *ViewController = [[SearchViewController alloc] init];
[self.navigationController pushViewController:ViewController animated:YES];
}
So I was able to make it with a simple UIButton but not with a UIButtonBarItem and I really don't know what's going on with it.
If you could help me I'd be very grateful.
Thanks.

Answer 1

Do this add selector to custom button as it is view of bar buttom:
[customButton addTarget:self action:#selector(buttonPressed:) forControlEvents:UIControlEventTouchUpInside];
EDIT : Note : the target and action of the UIBarButtonItem apply to custom views.

Answer 2

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setImage:[UIImage imageNamed:#"goback.png"] forState:UIControlStateNormal];
[button addTarget:self action:#selector(//HERE ! i don't know put what thing !) forControlEvents:UIControlEventTouchUpInside];
[button setFrame:CGRectMake(0, 0, 32, 32)];
self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:button];

TRY THIS
self.navigationItem.leftBarButtonItem=[[UIBarButtonItem alloc] initWithCustomView:[GlobalMethods buttonWithImage:#"top-nav-back" heighlightImageName:nil buttonFrame:CGRectMake(102, 1, 50, 30) selectorName:#selector(btnBackClicked:) target:self]];
+ (UIButton*)buttonWithImage:(NSString*)normalImageName heighlightImageName:(NSString*)heighlightImageName buttonFrame:(CGRect)buttonFrame selectorName:(SEL)selectorName target:(id)target
{
UIButton *objButton = [UIButton buttonWithType:UIButtonTypeCustom];
[objButton setFrame:buttonFrame];
[objButton addTarget:target action:selectorName forControlEvents:UIControlEventTouchUpInside];
[objButton setImage:[GlobalMethods getImageFromResourceBundle:normalImageName] forState:UIControlStateNormal];
if(heighlightImageName)
[objButton setImage:[GlobalMethods getImageFromResourceBundle:heighlightImageName] forState:UIControlStateDisabled];
if(heighlightImageName)
[objButton setImage:[GlobalMethods getImageFromResourceBundle:heighlightImageName] forState:UIControlStateSelected];
return objButton;
}

Answer 4

Try this..
[customButton addTarget:self action:#selector(buttonPressed:) forControlEvents:UIControlEventTouchUpInside];
in your customBarButton method..
I mean to say give selector to your button instead of bar button item..
Check and reply..

Answer 5

Just put this line in your code..
[backButton addTarget:self action:#selector(backBtnPressed:) forControlEvents:UIControlEventTouchUpInside];

Answer 6

This worked for me
UIButton * tmpButton = [self generateButtonwithImageName:#"Back.png" andSize:CGRectMake(0, 0, 55, 30)];
UIBarButtonItem * backButton = [[UIBarButtonItem alloc] initWithCustomView:tmpButton];
[tmpButton addTarget:self action:#selector(reload) forControlEvents:UIControlEventTouchUpInside];
self.navigationItem.leftBarButtonItem=backButton;
-(UIButton*)generateButtonwithImageName :(NSString*)imageName andSize:(CGRect)rect{
UIButton * button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame=rect;
[button setBackgroundImage:[UIImage imageNamed:imageName] forState:UIControlStateNormal];
return button;
}

//working for me
if([version floatValue] < 7.0)
{
[self.navigationController.navigationBar setBackgroundImage:[UIImage imageNamed:#"navi-bar.png"] forBarMetrics:UIBarMetricsDefault];
self.navigationController.navigationBar.opaque = YES;
closeButton = [[UIButton alloc]initWithFrame:CGRectMake(0, 0, 35, 30)];
[closeButton setImage:[UIImage imageNamed:#"btn_end.png"] forState:UIControlStateNormal];
[closeButton setImage:[UIImage imageNamed:#"btn_end_on.png"] forState:UIControlStateHighlighted];
[closeButton addTarget:self action:#selector(actionClose) forControlEvents:UIControlEventTouchUpInside];
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc]initWithCustomView:closeButton];
}
else{
/*add button back to navigation*//*add buttom back to navigation*/
UIBarButtonItem *itemBack = [[UIBarButtonItem alloc]initWithTitle:#"完了" style:UIBarButtonItemStylePlain target:self action:#selector(actionClose)];
self.navigationItem.rightBarButtonItem = itemBack;
}
