I wrote the following code to make my toolbar transparent.

[mtoolbar setBackgroundColor:[UIColor clearColor]];

How do I make UIToolbar

    This worked for me for iOS 6 and 7:

    UIGraphicsBeginImageContextWithOptions(CGSizeMake(1, 1), NO, 0.0);
    UIImage *blank = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    
    [self.toolBar setBackgroundImage:blank forToolbarPosition:UIToolbarPositionAny barMetrics:UIBarMetricsDefault];

    for (UIView * sv in [toolBar subviews])
    {
         [sv removeFromSuperview];
    }

    The following works in iOS 5 (and iOS 6 beta 4, although a slight top shadow is still visible there).

    Please note: Making a UIToolbar or UINavigationBar transparent is rarely a good idea, and modifying Apple's UIKit elements in such a way is bound to break sooner or later.

    TransparentToolbar.h

    #import <UIKit/UIKit.h>
    
    @interface TransparentToolbar : UIToolbar
    
    @end
    

    TransparentToolbar.m

    #import "TransparentToolbar.h"
    
    @implementation TransparentToolbar
    
    -(void)insertSubview:(UIView *)view atIndex:(NSInteger)index
    {
        //  This method is called with a view of class "UINavigationBarBackground" or "_UIToolbarBackground", respectively. It would be possible to check for this with NSStringFromClass([view class]) to be completely sure that we're skipping the right view.
    
        if (index != 0)
        {
            [super insertSubview:view atIndex:index];
        }
        else
        {
            // insert your custom background view, if you want to
        }
    }
    
    
    @end
    

    EDIT: In iOS 5+, it's also possible to simply set the backgroundImage (which could be transparent). This is certainly the "cleaner" solution, but is less flexible than a custom UIView.

    [someToolbar setBackgroundImage:[UIImage imageNamed:@"clear"] forToolbarPosition:UIToolbarPositionAny barMetrics:UIBarMetricsDefault];

    Check the below code

    [myToolbar setBarStyle:UIBarStyleBlack];
    [myToolbar setTranslucent:YES];

    Couldn't UIToolBar be transparent?

    you could also use the different approach

    You can set the property translucent to YES and see if this helps.

    Setting the property translucent to YES will not work in iOS 5 and below. Here's how it can be done without subclassing toolbar:

    const float colorMask[6] = {222, 255, 222, 255, 222, 255};
    UIImage *img = [[UIImage alloc] init];
    UIImage *maskedImage = [UIImage imageWithCGImage: CGImageCreateWithMaskingColors(img.CGImage, colorMask)];
    
    [self.toolbar setBackgroundImage:maskedImage forToolbarPosition:UIToolbarPositionAny barMetrics:UIBarMetricsDefault];
