because this setTintColor: is added in ios5 so you dont have it in ios4.3 — The iOSDev, Apr 24 '12 at 09:13

A good way to make this version independent is:

 if ([tabBarController.tabBar respondsToSelector:@selector(setTintColor:)]) {
        [tabBarController.tabBar setTintColor:color];
 }

In IOS 5 this will set the tabbar tintcolor and in lower versions it wont crash

According to the documentation tintColor is only available in iOS 5.0 and later. The clue was that the 4.3 simulator is saying unrecognized selector sent to instance which basically means the method doesn't exist.

You'll need to do one of the following:

Set your minimum required iOS to 5.0.

Only apply the tint when running on iOS 5.0 or greater.

Use an alternative method supported by both versions.

Documentation Excerpt:

tintColor

The tint color to apply to the tab bar background. @property(nonatomic, retain) UIColor *tintColor Availability
Available in iOS 5.0 and later.

do you know alternative method ? – Shady Ghalab Apr 24 '12 at 09:30
I've previously used a method like [this post](http://stackoverflow.com/questions/3339722/check-iphone-ios-version) to enable the tint for users on iOS 5 only, however depending on your application that might not be viable. – GregularExpressions Apr 24 '12 at 10:22

try this

tabB.tintColor=[UIColor colorWithRed:124.0/255.0 green:150.0/255.0 blue:32.0/255.0 alpha:1.0];
