Its like the dump says. It does not recognise the setFinishedSelectImage method as it was introduced in version 5 of the API. What you can do in your code is use SELECTORS and specifically respondsToSelector to see if the object has the method available. — Bushbert, Mar 08 '13 at 09:56

You can set image on tabbar using this code :

if ([[[UIDevice currentDevice] systemVersion] floatValue]<5.0)
{  
   self.tabBarItem = [[UITabBarItem alloc] initWithTitle:@"your name" image:[UIImage imageNamed:@"home-normal"] tag:0];
}
else
{
   self.tabBarItem = [[UITabBarItem alloc] init];
   self.tabBarItem.title = @"your name";
   [self.tabBarItem setFinishedSelectedImage:[UIImage imageNamed:@"home-active"] withFinishedUnselectedImage:[UIImage imageNamed:@"home-normal"]];
}

Ok, go to the documentation page for UITabBarItem, find that method, and tell me what it says under Availability

I'll give you a hint: 4.3 is not valid.
