could be made to work by adding

//Connect this to your toolbar in Interface Builder
@property (weak, nonatomic) IBOutlet UIToolbar *tref;
to your header. Then just do

 [tref setBackgroundImage:<myImage_1> forToolbarPosition:UIToolbarPositionTop barMetrics:UIBarMetricsDefault];

By subclassing UIToolBar and overriding drawRect, you eliminate some of UIToolBar's own drawing. Why not use the appearance api to set a background image:

[[UIToolbar appearance] setBackgroundImage:[UIImage imageNamed:@"UIToolBar_Background.png"]
                        forToolbarPosition:UIToolbarPositionBottom
                                barMetrics:UIBarMetricsDefault];

Example of [UIToolbar UIToolbarPositionBottom].

[_bottomToolbar setBackgroundImage:nil
                forToolbarPosition:UIToolbarPositionBottom
                        barMetrics:UIBarMetricsDefault];
[self.view addSubview:_bottomToolbar];

UIToolbar UIToolbarPositionBottom example.

UIImage *barImage=[[UIImage imageNamed:@"BarBg.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(27,0,27,0)];

UIToolbar setShadowImage forToolbarPosition example in Objective C (iOS).

UIToolbar setShadowImage forToolbarPosition

Sets the image to use for the toolbar shadow in a given position.

- (void)setShadowImage:(UIImage *)shadowImage forToolbarPosition:(UIToolbarPosition)topOrBottom

Parameters of [UIToolbar setShadowImage forToolbarPosition]
shadowImage
The image to use for the toolbar shadow in the position specified by topOrBottom.
topOrBottom
A toolbar position constant. You can use this parameter to indicate whether the shadowImage is intended for a toolbar at the top or bottom of the view.

Discussion of [UIToolbar setShadowImage forToolbarPosition]
When the shadowImage parameter is nil, the default shadow will be used. When non-nil, the shadowImage property is a custom shadow image to show instead of the default. Using the topOrBottom parameter, you can set a different shadow for toolbars at the top and bottom of the view. For a custom shadow image to be shown, a custom background image must also be set with the setBackgroundImage:forToolbarPosition:barMetrics: method. If the default background image is used, then the default shadow image will be used regardless of the value of the shadowImage parameter.

UIToolbar setTranslucent example in Objective C (iOS).

UIToolbar setTranslucent

A Boolean value that indicates whether the toolbar is translucent (YES) or not (NO).

@property(nonatomic, assign, getter=isTranslucent) BOOL translucent

Discussion of [UIToolbar setTranslucent]
Applying translucence to a toolbar is intended primarily for landscape orientation, when you want the user to be able to view the area beneath the toolbar. The default value for this property is NO. However, if you set the toolbar style to UIBarStyleBlackTranslucent, the value for this property is always YES.

UIToolbar setTranslucent example.

The best you can do is using

[helloToolbar setBarStyle:UIBarStyleBlack];
[helloToolbar setTranslucent:YES];
This will get you a black but translucent toolbar.

// Set properties to make background

UIToolbar also has a tintColor property, just like a UINavigationBar. You should be able to set one to the other:

myToolbar.tintColor = myNavBar.tintColor;
after you create your toolbar. Keep in mind that this code would only work if myNavBar had been loaded from the NIB, so it would be best to put this in viewWillAppear: or viewDidLoad.
