カスタム "押された" UIBarButtonItemの背景

Question

私は自分のUIBarButtonItemにカスタムの押された画像を設定しようとしていますが、何も動作していないようです。私の理解から、以下のコードは動作するはずですが、強調表示された状態の画像を設定しているにもかかわらず、ボタンは押されたときに全く同じように見えます。

アイデア？

UIImage *barButtonBackground = [[UIImage imageNamed:ANBarButtonItemBackgroundImageName] resizableImageWithCapInsets:UIEdgeInsetsMake(5.0f,5.0f, 5.0f, 5.0f)]; 
UIImage *barButtonPressedBackground = [[UIImage imageNamed:ANBarButtonPressedImageName] resizableImageWithCapInsets:UIEdgeInsetsMake(5.0f,5.0f, 5.0f, 5.0f)]; 

[self.navigationItem.leftBarButtonItem setBackgroundImage:barButtonBackground forState:UIControlStateNormal barMetrics:UIBarMetricsDefault]; 
[self.navigationItem.rightBarButtonItem setBackgroundImage:barButtonBackground forState:UIControlStateNormal barMetrics:UIBarMetricsDefault]; 

[self.navigationItem.leftBarButtonItem setBackgroundImage:barButtonPressedBackground forState:UIControlStateHighlighted barMetrics:UIBarMetricsDefault]; 
[self.navigationItem.rightBarButtonItem setBackgroundImage:barButtonPressedBackground forState:UIControlStateHighlighted barMetrics:UIBarMetricsDefault];

は、私はあなたがしてcustom UIBarButtonItemためのビューとして、このUIButtonを使用し、あなたのカラースキームに合わせ異なる制御状態ためcustom UIButton背景画像とを作成するべきだと思います。あなたには、いくつかの他のリファレンスは、あなたがこの美しいリンクを介して行くことができますしたい場合は

UIButton *customButton = [UIButton buttonWithType:...]; 

[customButton setBackgroundImage:barButtonBackground forState:UIControlStateNormal]; 
[customButton setBackgroundImage:barButtonPressedBackground forState:UIControlStateSelected]; 

UIBarButtonItem *barButtonItem = [[UIBarButtonItem alloc] initWithCustomView: customButton];

あなたは、おそらくこのようにしてみてください。私のために働く。

UIBarButtonItem + customLook.h

#import <UIKit/UIKit.h> 

@interface UIBarButtonItem (customLook) 

+ (UIBarButtonItem *)barButtonItemWithImage:(UIImage *)image selectedBackGroundImage:(UIImage *)selected target:(id)target action:(SEL)selector; 

@end 

UIBarButtonItem + customLook.m

#import "UIBarButtonItem+customLook.h" 

@implementation UIBarButtonItem (customLook) 

+ (UIBarButtonItem *)barButtonItemWithImage:(UIImage *)image selectedBackGroundImage:(UIImage *)selected target:(id)target action:(SEL)selector 
{ 
    UIButton* someButton = [UIButton buttonWithType:UIButtonTypeCustom]; 
    [someButton setImage:image forState:UIControlStateNormal]; 
    [someButton setBackgroundImage:selected forState:UIControlStateSelected]; 

    CGSize size = image.size; 
    CGRect frame = CGRectZero; 
    frame.size.width = size.width; 
    frame.size.height = 30.0f; // Standart height 
    someButton.frame = frame; 

    [someButton addTarget:target action:selector forControlEvents:UIControlEventTouchUpInside]; 

    UIBarButtonItem* backButton = [[UIBarButtonItem alloc] initWithCustomView:someButton]; 

    return backButton; 
} 

@end 

一部：

UIImage* image3 = [UIImage imageNamed:@"mail-48_24.png"]; 
CGRect frameimg = CGRectMake(0, 0, image3.size.width, image3.size.height); 
UIButton *someButton = [[UIButton alloc] initWithFrame:frameimg]; 
[someButton setBackgroundImage:image3 forState:UIControlStateNormal]; 
[someButton addTarget:self action:@selector(sendmail) 
    forControlEvents:UIControlEventTouchUpInside]; 
[someButton setShowsTouchWhenHighlighted:YES]; 

UIBarButtonItem *mailbutton =[[UIBarButtonItem alloc] initWithCustomView:someButton]; 
self.navigationItem.rightBarButtonItem=mailbutton; 
[someButton release];

多分これは（ちょうどそのプロジェクトにファイルを追加）のお手伝いをしますビューコントローラ：

#import "UIBarButtonItem+customLook.h" 
... 

- (void)viewDidLoad 
{ 
    [super viewDidLoad]; 

    UIBarButtonItem *bbi = [UIBarButtonItem barButtonItemWithImage:[UIImage imageNamed:@"29-heart-selected.png"] 
              selectedBackGroundImage:[UIImage imageNamed:@"DarkButton_Pressed.png"] 
                  target:self 
                  action:@selector(someAction:)]; 
    self.navigationItem.rightBarButtonItem = bbi; 
} 

...

- (void)someAction:(id)sender 
{ 
    [(UIButton *)sender setSelected:YES]; 
}

UIImage* btnImage = [UIImage imageNamed:@"share-icon-deselected-16x16.png"]; 
    CGRect frameimg = CGRectMake(0, 0, btnImage.size.width, btnImage.size.height); 
    UIButton *someButton = [[UIButton alloc] initWithFrame:frameimg]; 
    [someButton setBackgroundImage:btnImage forState:UIControlStateNormal]; 
    [someButton addTarget:self action:@selector(share:) 
     forControlEvents:UIControlEventTouchUpInside]; 
    [someButton setShowsTouchWhenHighlighted:YES]; 

    UIBarButtonItem *mailbutton =[[UIBarButtonItem alloc] initWithCustomView:someButton]; 
    self.navigationItem.rightBarButtonItem=mailbutton; 




- (void)share:(id)sender{ 
    UIButton*btn = (UIButton*)sender; 
    if (btn.isSelected) 
    { 
     [btn setSelected:NO]; 
     [btn setBackgroundImage:[UIImage imageNamed:@"share-icon-deselected-16x16.png"] forState:UIControlStateNormal]; 
    } 
    else 
    { 
     [btn setSelected:YES]; 
     [btn setBackgroundImage:[UIImage imageNamed:@"share-icon-selected-16x16.png"] forState:UIControlStateNormal]; 
    } 
};
