iOS*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)(1 * 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
