@property (weak, nonatomic) IBOutlet UISegmentedControl *Sgment;

@end

@implementation ArenaViewController

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

    //設置segument普通狀態下的的背景圖片
    
    [self.Sgment setBackgroundImage:[UIImage imageNamed:@"CPArenaSegmentBG"] forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
    
    //設置segument選中狀態下的的背景圖片
    [self.Sgment setBackgroundImage:[UIImage imageNamed:@"CPArenaSegmentSelectedBG"] forState:UIControlStateSelected barMetrics:UIBarMetricsDefault];

    //設置segument的文字顏色
    NSDictionary *attri = @{NSForegroundColorAttributeName : [UIColor whiteColor]};
    //默認情況下
    [self.Sgment setTitleTextAttributes:attri forState:UIControlStateNormal];
    //選中情況下
    [self.Sgment setTitleTextAttributes:attri forState:UIControlStateSelected];
