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

 1 @interface ChaosSettingCell ()
 2 /** arrow */
 3 @property(nonatomic,strong) UIImageView *arrowView;
 4 /** switch */
 5 @property(nonatomic,strong) UISwitch *switchView;
 6 @end
 7 @implementation ChaosSettingCell
 8 
 9 - (UIImageView *)arrowView
10 {
11     if (_arrowView == nil) {
12         _arrowView = [[UIImageView alloc]initWithImage: [UIImage imageNamed:@"arrow_right"]];
13     }
14     return _arrowView;
15 }
16 
17 - (UISwitch *)switchView
18 {
19     if (_switchView == nil) {
20         _switchView = [[UISwitch alloc]init];
21     }
22     return _switchView;
23 }
24 
25 #pragma mark - 自定义cell内部实现，，返回cell的方法
26 + (ChaosSettingCell *)cellWithTableView:(UITableView *)tableView style:(UITableViewCellStyle)style
27 {
28     static NSString *ID = @"cell";
29     
30     ChaosSettingCell *cell = [tableView dequeueReusableCellWithIdentifier:ID];
31     if (cell == nil) {
32         cell = [[ChaosSettingCell alloc] initWithStyle:style reuseIdentifier:ID];
33     }
34     return cell;
35 }
36 
37 // 重写cell的set方法，给cell赋值
38 - (void)setItem:(ChaosSettingItem *)item
39 {
40     _item = item;
41     
42     [self setUpData];
43     
44     [self setUpAccessoryView];
45 }
46 
47 // 给cell绑定数据
48 - (void)setUpData
49 {
50     self.imageView.image = self.item.icon;
51     self.textLabel.text = self.item.title;
52     self.detailTextLabel.text = self.item.subTitle;
53 }
54 // 设置cell的辅助视图
55 - (void)setUpAccessoryView
56 {
57     if ([self.item isKindOfClass:[ChaosSettingItemArrow class]]) { // 箭头
58         
59         self.accessoryView = self.arrowView;
60         
61     } else if([self.item isKindOfClass:[ChaosSettingItemSwitch class]]){ // 开关
62         
63         self.accessoryView = self.switchView;
64         self.selectionStyle = UITableViewCellSelectionStyleNone;
65         
66     } else { // 还原
67         
68         self.accessoryView = nil;
69         self.selectionStyle = UITableViewCellSelectionStyleDefault;
70     }
71 }
72 
73 @end

通过设置不同的模型，完全实现了展示的效果

View Code

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
