Answer 1

이 코드를 사용하여 TabBar의에 이미지를 설정할 수 있습니다

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"]]; 
}
