issue changing UIToolbar tintColor

Question

I have the following code:

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization    
        webControlsToolbar_ = [[UIToolbar alloc] init];
        [self.webControlsToolbar_ setTintColor:[UIColor colorWithRed:246.0/255.0 green:246.0/255.0 blue:246.0/255.0 alpha:1]];

Any idea why the color is still solid black? In my view did load I added the toolbar:

self.webControlsToolbar_.frame = CGRectMake(0, self.view.frameHeight - self.webControlsToolbar_.frameHeight + 1.0, self.view.frameWidth, self.webControlsToolbar_.frameHeight);
        [self.view addSubview:self.webControlsToolbar_];

Answer 1

I've run into a similar problem before. I resolved it by setting the tint color immediately before showing the toolbar in code. See if that works for you.

Answer 2

我发现更容易按照实用工具栏的要求完全设置按钮，标签等的背景颜色，然后创建一个名为say，myOutlet的插座，并执行以下操作：

[self.webControlsToolbar_ setTintColor:myOutlet.backgroundColor];

Answer 3

The issue is at the line

self.webControlsToolbar_.frame = CGRectMake(0, self.view.frameHeight - self.webControlsToolbar_.frameHeight + 1.0, self.view.frameWidth, self.webControlsToolbar_.frameHeight);

Try to NSLog a self.webControlsToolbar_.frameHeight property and you should see that is zero after [UIToolBar new]; Use a constant height instead.

You have to change this attribute in the viewDidLoad method:

-(void)viewDidLoad{
    [super viewDidLoad];
    //Custom initialization
    [self.webControlsToolbar_ setTintColor:[UIColor colorWithRed:246.0/255.0 green:246.0/255.0 blue:246.0/255.0 alpha:1]];
