iOS彩票项目--第六天，运用MVC思想搭建设置界面（非storyboard方法）

一、我只想说封装的思想很重要，MVC的思想也很重要,利用MVC思想搭建一下的界面

• 先说显示出来的cell，有三种（图中的两种，还有一种是最普通的，没有图片的），这种显示不同的cell，交给模型来处理，模型中的数据决定了要显示的样式。
• 但是有考虑到功能的不一样，所以运用了面向对象的思想，同时继承自cell，实现具体到每一种会有单独的样式和功能。
• 不同的样式只要根据类名来判断，展示不同的效果。

　　　　

• 初始化cell，通过类名来判断是带箭头的cell还是带开关的cell

 @interface ChaosSettingCell ()
 /** arrow */
 @property(nonatomic,strong) UIImageView *arrowView;
 /** switch */
 @property(nonatomic,strong) UISwitch *switchView;
 @end
 @implementation ChaosSettingCell

 - (UIImageView *)arrowView
 {
     if (_arrowView == nil) {
         _arrowView = [[UIImageView alloc]initWithImage: [UIImage imageNamed:@"arrow_right"]];
     }
     return _arrowView;
 }

 - (UISwitch *)switchView
 {
     if (_switchView == nil) {
         _switchView = [[UISwitch alloc]init];
     }
     return _switchView;
 }

 #pragma mark - 自定义cell内部实现，，返回cell的方法
 + (ChaosSettingCell *)cellWithTableView:(UITableView *)tableView style:(UITableViewCellStyle)style
 {
     static NSString *ID = @"cell";

     ChaosSettingCell *cell = [tableView dequeueReusableCellWithIdentifier:ID];
     if (cell == nil) {
         cell = [[ChaosSettingCell alloc] initWithStyle:style reuseIdentifier:ID];
     }
     return cell;
 }

 // 重写cell的set方法，给cell赋值
 - (void)setItem:(ChaosSettingItem *)item
 {
     _item = item;

     [self setUpData];

     [self setUpAccessoryView];
 }

 // 给cell绑定数据
 - (void)setUpData
 {
     self.imageView.image = self.item.icon;
     self.textLabel.text = self.item.title;
     self.detailTextLabel.text = self.item.subTitle;
 }
 // 设置cell的辅助视图
 - (void)setUpAccessoryView
 {
     if ([self.item isKindOfClass:[ChaosSettingItemArrow class]]) { // 箭头

         self.accessoryView = self.arrowView;

     } else if([self.item isKindOfClass:[ChaosSettingItemSwitch class]]){ // 开关

         self.accessoryView = self.switchView;
         self.selectionStyle = UITableViewCellSelectionStyleNone;

     } else { // 还原

         self.accessoryView = nil;
         self.selectionStyle = UITableViewCellSelectionStyleDefault;
     }
 }

 @end

• 通过设置不同的模型，完全实现了展示的效果

 #import "ChaosSettingViewController.h"
 #import "ChaosHelpViewController.h"
 #import "ChaosSettingGroup.h"

 #import "ChaosPushViewController.h"
 #import "ChaosHelpViewController.h"

 #import "ChaosBlurView.h"
 #import "MBProgressHUD+XMG.h"

 @interface ChaosSettingViewController ()

 @end

 @implementation ChaosSettingViewController

 - (instancetype)init
 {
     return [super initWithStyle:UITableViewStyleGrouped];
 }

 - (void)viewDidLoad {
     [super viewDidLoad];

     self.title = @"设置";
     self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"常见问题" style:UIBarButtonItemStyleBordered target:self action:@selector(help)];

     [self setUpGroup0];
     [self setUpGroup1];
     [self setUpGroup2];
 }

 - (void)help
 {
     ChaosHelpViewController *helpVC = [[ChaosHelpViewController alloc] init];

     helpVC.title = @"帮助";

     [self.navigationController pushViewController:helpVC animated:YES];
 }

 - (void)setUpGroup0
 {
     ChaosSettingItemArrow *item = [ChaosSettingItemArrow itemWithImage:[UIImage imageNamed:@"RedeemCode"] title:@"使用兑换码"];
     item.pushVCName = [UITableViewController class];
     NSArray *items = @[item];
     ChaosSettingGroup *group = [ChaosSettingGroup groupWithHeader:nil footer:nil items:items];
     [self.sections addObject:group];
 }
 - (void)setUpGroup1
 {
     ChaosSettingItemArrow *item = [ChaosSettingItemArrow itemWithImage:[UIImage imageNamed:@"MorePush"] title:@"推送和提醒"];

     item.pushVCName = [ChaosPushViewController class];

     ChaosSettingItemSwitch *item1 = [ChaosSettingItemSwitch itemWithImage:[UIImage imageNamed:@"more_homeshake"] title:@"摇一摇机选"];
     ChaosSettingItemSwitch *item2 = [ChaosSettingItemSwitch itemWithImage:[UIImage imageNamed:@"sound_Effect"] title:@"声音效果"];
     ChaosSettingItemSwitch *item3 = [ChaosSettingItemSwitch itemWithImage:[UIImage imageNamed:@"More_LotteryRecommend"] title:@"采购小助手"];
     NSArray *items = @[item,item1,item2,item3];
     ChaosSettingGroup *group = [ChaosSettingGroup groupWithHeader:nil footer:nil items:items];
     [self.sections addObject:group];
 }
 - (void)setUpGroup2
 {
     ChaosSettingItemArrow *item = [ChaosSettingItemArrow itemWithImage:[UIImage imageNamed:@"MoreUpdate"] title:@"检查新版本"];
     item.itemOpertion = ^(NSIndexPath *indexPath){
         // 高斯模糊框架的应用
         ChaosBlurView *blurView = [[ChaosBlurView alloc] initWithFrame:ChaosScreenBounds];
         [ChaosKeyWindow addSubview:blurView];

         [MBProgressHUD showSuccess:@"没有新版本可更新"];

         dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)( * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
             [blurView removeFromSuperview];
         });

     };
     ChaosSettingItemArrow *item1 = [ChaosSettingItemArrow itemWithImage:[UIImage imageNamed:@"MoreShare"] title:@"分享"];
     ChaosSettingItemArrow *item2 = [ChaosSettingItemArrow itemWithImage:[UIImage imageNamed:@"MoreNetease"] title:@"产品推荐"];
     ChaosSettingItemArrow *item3 = [ChaosSettingItemArrow itemWithImage:[UIImage imageNamed:@"MoreAbout"] title:@"关于"];
     NSArray *items = @[item,item1,item2,item3];
     ChaosSettingGroup *group = [ChaosSettingGroup groupWithHeader:nil footer:nil items:items];
     [self.sections addObject:group];
 }

 @end

• 模型中的

  /** itemblock */

  @property(nonatomic,strong) void(^itemOpertion)(NSIndexPath *indexPath); 这个属性用来保存代码段。项目中是点击了相应的cell后需要做的事情保存到了block中
