如何更改UINavigationBar rightButton圖像？

我想改變viewWillAppear UINavigationBar的rightButton形象，爲此我想這一點：如何更改UINavigationBar rightButton圖像？

self.navigationController?.navigationItem.rightBarButtonItem?.image = UIImage(named: "bookmark")

但它不會改變我的rightButton的形象。我如何解決它並改變我的形象？

@EICaptain但我不想TI刪除，每次加我扣 –

@KumarKL其設置爲前請仔細閱讀我的問題**重複**！ –

試試這個

var changeImage:UIImage = UIImage(named: "bookmark")! 
changeImage = changeImage.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal) 
var rightButton = UIBarButtonItem(image: changeImage, style: UIBarButtonItemStyle.Bordered, target: self, action: "xxxx") 
self.navigationItem.rightBarButtonItem = rightButton

選擇-2

爲UIBarButtonSystemItemBookmarks

var rightButton: UIBarButtonItem = UIBarButtonItem(barButtonSystemItem: .Bookmarks, target: self, action: "xxxx") 
self.navigationItem.rightBarButtonItem = rightButton

書籤使用默認的一些功能默認UIBarbuttonItems是

typedef NS_ENUM(NSInteger, UIBarButtonSystemItem) { 
UIBarButtonSystemItemDone, 
UIBarButtonSystemItemCancel, 
UIBarButtonSystemItemEdit, 
UIBarButtonSystemItemSave, 
UIBarButtonSystemItemAdd, 
UIBarButtonSystemItemFlexibleSpace, 
UIBarButtonSystemItemFixedSpace, 
UIBarButtonSystemItemCompose, 
UIBarButtonSystemItemReply, 
UIBarButtonSystemItemAction, 
UIBarButtonSystemItemOrganize, 
UIBarButtonSystemItemBookmarks, 
UIBarButtonSystemItemSearch, 
UIBarButtonSystemItemRefresh, 
UIBarButtonSystemItemStop, 
UIBarButtonSystemItemCamera, 
UIBarButtonSystemItemTrash, 
UIBarButtonSystemItemPlay, 
UIBarButtonSystemItemPause, 
UIBarButtonSystemItemRewind, 
UIBarButtonSystemItemFastForward, 
UIBarButtonSystemItemUndo NS_ENUM_AVAILABLE_IOS(3_0), 
UIBarButtonSystemItemRedo NS_ENUM_AVAILABLE_IOS(3_0), 
UIBarButtonSystemItemPageCurl NS_ENUM_AVAILABLE_IOS(4_0), 
};

我不是快速家庭，嘗試一次 –

self.navigationController .navigationItem.rightBarButtonItem =圖像配的UIBarButtonItem？（圖像：//映像名稱，風格：UIBarButtonItemStyle.Plain，目標：自我，動作：//動作名稱）

試試這個，我新來這就是爲什麼我一直在Objective C.做到了這一點代碼迅速

UIButton *btnRight = [UIButton buttonWithType:UIButtonTypeCustom]; 


[btnRight setFrame : CGRectMake(0, 0, 60, 35)]; 

[btnRight setImage:[UIImage imageNamed:@"prefferedImage"] forState:UIControlStateNormal]; 
[btnRight addTarget:self action:@selector(defindeActionMethod:) forControlEvents:UIControlEventTouchUpInside]; 

[btnRight setContentHorizontalAlignment:UIControlContentHorizontalAlignmentRight]; 

btnRight.imageView.contentMode = UIViewContentModeScaleAspectFit; 
btnRight.contentHorizontalAlignment = UIControlContentHorizontalAlignmentRight; 
btnRight.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter; 

UIBarButtonItem *rightBarButton = [[UIBarButtonItem alloc] initWithCustomView:btnRight]; 
[rightBarButton setTintColor:[UIColor whiteColor]]; 
self.navigationItem.rightBarButtonItem = rightBarButton;
