对plist构建数据模型，完成封装实现数据分离

标签：ios   plist   数据封装   

pList是我们常用的数据格式，首先来看我们的pList文件：是一个数组，里面存放字典，字典分为两项，name对应名字，icon对应图片名字，我们还有一组以此命名的图片。

对此，为了封装数据，我们建一个类，取名AppInfo.

AppInfo.h文件：

#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>

@interface AppInfo : NSObject

@property (nonatomic,copy) NSString *name;
@property (nonatomic,copy) NSString *icon;

@property (nonatomic,strong,readonly) UIImage *image;

/** 使用字典实例化 */
+ (instancetype)initWithDictionary:(NSDictionary *)dict;
/** 类方法快速实例化 */
+ (instancetype)appInfoWithDictionary:(NSDictionary *)dict;

+ (NSArray *)appList;

@end

 AppInfo.m文件：

#import "AppInfo.h"

@implementation AppInfo
@synthesize image = _image;

- (UIImage *)image
{
    if(_image == nil ){
        _image = [UIImage imageNamed:self.icon];
    }
    return _image;
}

- (instancetype)initWithDictionary:(NSDictionary *)dict
{
    self = [super init];
    if (self) {
        //KVC
        [self setValuesForKeysWithDictionary:dict];
        
    }
    return self;
}

+ (instancetype)appInfoWithDictionary:(NSDictionary *)dict
{
    return [[self alloc]initWithDictionary:dict];
}

+(NSArray *)appList
{
    NSArray *array = [NSArray arrayWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"app.plist" ofType:nil]];
    
    NSMutableArray *arrayM = [NSMutableArray array];
    for (NSDictionary *dict in array) {
        AppInfo *appInfo = [AppInfo appInfoWithDictionary:dict];
        [arrayM addObject:appInfo];
    }
    
    return arrayM;
}

@end

NSArray *array = [AppInfo appList];
