@implementation ArenaViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    
    //设置控制器view的背景图片
    self.view.layer.contents = (__bridge id)([UIImage imageNamed:@"NLArenaBackground"].CGImage);

    //设置segument普通状态下的的背景图片
    
    [self.Sgment setBackgroundImage:[UIImage imageNamed:@"CPArenaSegmentBG"] forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
    
    //设置segument选中状态下的的背景图片
    [self.Sgment setBackgroundImage:[UIImage imageNamed:@"CPArenaSegmentSelectedBG"] forState:UIControlStateSelected barMetrics:UIBarMetricsDefault];

    //设置segument的文字颜色
    NSDictionary *attri = @{NSForegroundColorAttributeName : [UIColor whiteColor]};
    //默认情况下
    [self.Sgment setTitleTextAttributes:attri forState:UIControlStateNormal];
    //选中情况下
    [self.Sgment setTitleTextAttributes:attri forState:UIControlStateSelected];
