Button color in Navigation bar - iPhone

问题

How do you to set the tint of this yellow button to be gray? I have tried adding an image, but have had no luck.

Here is the screenshot:

Here is my current code:

- (id)initWithStyle:(UITableViewStyle)style {     if (self = [super initWithStyle:style]) {          UIBarButtonItem *addButton = [[UIBarButtonItem alloc]                                       initWithTitle:NSLocalizedString(@"Settings", @"")                                       style:UIBarButtonItemStyleDone                                       target:self                                       action:@selector(GoToSettings)];         [addButton setImage:[[UIImage imageNamed:@"bg_table.png"] retain]];          self.navigationItem.rightBarButtonItem = addButton;         self.navigationItem.hidesBackButton = TRUE;         self.view.backgroundColor = [UIColor blackColor];     }     return self; } 

回答1:

It is not possible without your custom image.

回答2:

self.navigationItem.rightBarButtonItem.tintColor = [UIColor colorWithRed:0.1f green:0.66f blue:0.26f alpha:0.7];

From iOS 5.0 and on you can use:

    [[UINavigationBar appearance] setTintColor:[UIColor yellowColor]]; 

回答4:

 UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];  [button setBackgroundImage:[UIImage imageNamed:@"button_main.png"]                                        forState:UIControlStateNormal];  [button addTarget:self action:@selector(GotoSettings)               forControlEvents:UIControlEventTouchUpInside];  button.frame = CGRectMake(x, y, x1, x2);   UIBarButtonItem *menuButton = [[UIBarButtonItem alloc] initWithCustomView:menu];  self.navigationItem.rightBarButtonItem = menuButton;   [button release];  [menuButton release]; 

回答5:

Actually it's possible without using image for buttons.

viewController.navigationController.navigationBar.tintColor =      [UIColor colorWithRed:0.16f green:0.36f blue:0.46 alpha:0.8]; 

回答6:

when you set your image of the button in navigation bar, you may want to set UIImageRenderingModeAlwaysOriginal for it:

[addButton setImage:[[[UIImage imageNamed:@"bg_table.png"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal] retain]]; 

here is the reference.
