    self.view.backgroundColor = [UIColor yellowColor];
    self.title = @"Leader";
    
    //    带图片的按钮
    UIButton *informationCardBtn = [UIButton buttonWithType:UIButtonTypeCustom];
    [informationCardBtn addTarget:self action:@selector(mineButtonAction) forControlEvents:UIControlEventTouchUpInside];
    [informationCardBtn setImage:[UIImage imageNamed:@"mine"] forState:UIControlStateNormal];
    
    [informationCardBtn sizeToFit];
    UIBarButtonItem *informationCardItem = [[UIBarButtonItem alloc] initWithCustomView:informationCardBtn];
