用于快速構建設置界面 UITableView 子類：XFSettings

使用 UITableViewController 為基類，用于快速構建設置界面，可定制性強，有多個 cell 類型緩存重用，擴展性強，可繼承 XFSettingCell 或功能更強大的 XFSettingInfoCell 作為父類進行自定義樣式，采用 JOSN 進行布局和對功能的添加。

代碼示例：

//.h
#import "XFSettings.h"
@interface ViewController : XFBaseSettingTableViewController
@end
//.m
@interface ViewController ()<XFBaseSettingDataSource>
@end
@implementation ViewController
- (void)viewDidLoad {
    [super viewDidLoad]; // must invoke super method.
    self.navigationItem.title = @"設置";
    self.view.backgroundColor = [UIColor whiteColor];
    self.dataSource = self; // set self as dataSource.
}
- (NSArray *)settingItems
{
    return @[ // groupArr
             @{ // groupModel
                 XFSettingGroupHeader: @"基本信息",
                 XFSettingGroupItems : @[ // items
                         @{ // itemModel
                             XFSettingItemTitle: @"我的朋友",
                             XFSettingItemIcon : @"1435582804_group",
                             XFSettingItemClass : [XFSettingInfoItem class], // 這個字段用于判斷是否有右邊輔助功能的cell,不寫則沒有
                             XFSettingItemAttrDetailText : @"你的好友",
                             XFSettingItemRelatedCellClass:[XFSettingInfoDotCell class],// 自定義的cell
                             XFSettingItemDestViewControllerClass : [XFNewFriendViewController class], // 如果有目標控制器
