视图控制器至少须要设置标题和图片,能够在Interface Builder中设置Tab Bar Item,也能够在试图控制器类中覆盖initWithNibName:bundle:方法,示例以下。ui
-(id)initWithNibName:(NSString *)nibName bundle:(NSBundle *)nibBundle { self = [super initWithNibName:nibName bundle:nibBundle]; if (self) { self.title = @"Title"; self.tabBarItem.image = [UIImage imageNamed:@"image.png"]; } return self; }经过设置试图控制器的tabBarItem属性可更改Tab Bar Item的外观。除了title和image,还有badgeValue属性用来设置右上角的文字,好比,在App Store界面显示软件的可更新数等
