数据解析

model 层

      .h 文件  

- (instancetype)initModel: (NSDictionary *)dic;

+ (instancetype)HuiDiao: (NSDictionary *)dic;

.m  

- (instancetype)initModel: (NSDictionary *)dic

{

if (self = [super init])

{

[self setValuesForKeysWithDictionary:dic];

}

return self;

}

+ (instancetype)HuiDiao: (NSDictionary *)dic

{

return  [[self alloc]initModel:dic];

}

表格中自定义cell 利用第三方 展示图片"SDWebImage"

#import "UIImageView+WebCache.h"

[cell.imageVi sd_setImageWithURL:[NSURL URLWithString:model.pic] placeholderImage:[UIImage imageNamed:@"3dcbc92925711f3d!400x400_big.jpg"] completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, NSURL *imageURL) {

}];

block 传值  业务处理层. h

typedef void (^shipinBlock)(NSMutableArray *arr);

//声明 block 属性

@property (nonatomic,strong) shipinBlock shujublock;

+ (instancetype)DL;

//用于回传数据的方法

//声明block 的方法

//-(void)shujuchuanzhi:(shujuBlock)shuju;

- (void)GETJSON:(NSString *)urlStr shujuchuanzhi:(shipinBlock)shuju;

//业务处理层. m

+ (instancetype)DL

{

if (shipin == nil)

{

shipin = [[shipinDataBase alloc]init];

}

return shipin;

}

-(void)GETJSON:(NSString *)yaowenUrlStr shujuchuanzhi:(shipinBlock)shuju

{

_dic = [[NSMutableDictionary alloc]init];

_allarr = [NSMutableArray array];
