When you add Tab Bar in your iPhone project, by default its background color is black and selection color is blue. But if you need to change it add these code in your project file RootViewController-

// RootViewController.h file

@interface UITabBar (ColorExtensions)

– (void)recolorItemsWithColor:(UIColor *)color shadowColor:(UIColor *)shadowColor shadowOffset:(CGSize)shadowOffset shadowBlur:(CGFloat)shadowBlur;

@end

@interface UITabBarItem (Private)

@property(retain, nonatomic) UIImage *selectedImage;

– (void)_updateView;

@end

//RootViewController.m file

@implementation UITabBar (ColorExtensions)

– (void)recolorItemsWithColor:(UIColor *)color shadowColor:(UIColor *)shadowColor shadowOffset:(CGSize)shadowOffset shadowBlur:(CGFloat)shadowBlur

{

CGColorRef cgColor = [color CGColor];

CGColorRef cgShadowColor = [shadowColor CGColor];

for (UITabBarItem *item in [self items])

if ([item respondsToSelector:@selector(selectedImage)] &&

[item respondsToSelector:@selector(setSelectedImage:)] &&

[item respondsToSelector:@selector(_updateView)])

{

CGRect contextRect;

contextRect.origin.x = 0.0f;

contextRect.origin.y = 0.0f;

contextRect.size = [[item selectedImage] size];

// Retrieve source image and begin image context

UIImage *itemImage = [item image];

CGSize itemImageSize = [itemImage size];

CGPoint itemImagePosition;

itemImagePosition.x = ceilf((contextRect.size.width – itemImageSize.width) / 2);

itemImagePosition.y = ceilf((contextRect.size.height – itemImageSize.height) / 2);

UIGraphicsBeginImageContext(contextRect.size);

CGContextRef c = UIGraphicsGetCurrentContext();

// Setup shadow

CGContextSetShadowWithColor(c, shadowOffset, shadowBlur, cgShadowColor);

// Setup transparency layer and clip to mask

CGContextBeginTransparencyLayer(c, NULL);

CGContextScaleCTM(c, 1.0, -1.0);

CGContextClipToMask(c, CGRectMake(itemImagePosition.x, -itemImagePosition.y, itemImageSize.width, -itemImageSize.height), [itemImage CGImage]);

// Fill and end the transparency layer

CGContextSetFillColorWithColor(c, cgColor);

contextRect.size.height = -contextRect.size.height;

CGContextFillRect(c, contextRect);

CGContextEndTransparencyLayer(c);

// Set selected image and end context

[item setSelectedImage:UIGraphicsGetImageFromCurrentImageContext()];

UIGraphicsEndImageContext();

// Update the view

[item _updateView];

}

}

@end

// in ViewDidLoad{

// Give the selection color and its shadow

[[[self tabBarController] tabBar] recolorItemsWithColor:[UIColor whiteColor] shadowColor:[UIColor blackColor] shadowOffset:CGSizeMake(0.0f, -1.0f) shadowBlur:3.0f];

}

It’s works great friends 🙂

!! Enjoy !!
