我不明白为什么导航栏不会在以下代码中添加除取消按钮之外的任何按钮，这种事情是在 Viber 应用程序中完成的，所以有可能

 ABPeoplePickerNavigationController *picker = [[ABPeoplePickerNavigationController     alloc] init];
picker.navigationBar.tintColor=[UIColor colorWithRed:91.0/256.0 green:72.0/256.0 blue:110.0/256.0 alpha:1.0];
//picker.navigationController.navigationBar.topItem.rightBarButtonItem = nil;
[picker.navigationBar setHidden:NO];
picker.peoplePickerDelegate = self;
// Display only a person's phone, email, and birthdate
NSArray *displayedItems = [NSArray arrayWithObjects:[NSNumber numberWithInt:kABPersonPhoneProperty], 
                           [NSNumber numberWithInt:kABPersonEmailProperty],
                           [NSNumber numberWithInt:kABPersonBirthdayProperty], nil];

//picker.navigationBarHidden=TRUE;
picker.displayedProperties = displayedItems;
//UIBarButtonItem *addbutton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(AddContact)];          
   //   picker.navigationController.navigationBar.topItem.rightBarButtonItem = addbutton;

[self presentModalViewController:picker animated:NO];
[picker release];
//[addbutton release];

有人可以帮忙吗

我可以向您展示如何将自定义按钮添加到导航栏。如果有帮助，请使用此代码，

UIImage *buttonImage = [UIImage imageNamed:@"Done.png"];

    UIButton *aButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];

    [aButton setImage:buttonImage forState:UIControlStateNormal];

    aButton.frame = CGRectMake(0.0, 0.0, buttonImage.size.width, buttonImage.size.height);

    UIBarButtonItem *aBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:aButton];

    [aButtonaddTarget:selfaction:@selector(navigatehome)forControlEvents:UIControlEventTouchUpInside];

    self.navigationItem.rightBarButtonItem = aBarButtonItem;

    [aBarButtonItem release];
