iOS数据解析

• 从服务器获取数据之后，接下来我们就需要对数据进行解析，转换成模型；有时候数据比较复杂，搞得我头晕脑胀的，就记录一下

• 数据是这样的

• 取出 templist 数组里面的字典，然后字典里面又有一个数组 Labels
• 创建两个模型，一个是 templist 里面的字典的模型，另外一个是字典里面的的Labels的字典里面的模型

#import <Foundation/Foundation.h>

@interface ModelLabel : NSObject

@property (nonatomic, copy) NSString *content;
@property (nonatomic, copy) NSString *fontcolor;
@property (nonatomic, copy) NSString *bgcolor;

+(instancetype)modelWithDict:(NSDictionary *)dict;

@end

#import "ModelLabel.h"

@implementation ModelLabel

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

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

-(void)setValue:(id)value forUndefinedKey:(NSString *)key{
    
}

@end

.h
#import <Foundation/Foundation.h>
#import "ModelLabel.h"

@interface ModelList : NSObject

@property (nonatomic, copy) NSString *time_waitpost;
@property (nonatomic, copy) NSString *bizname;
@property (nonatomic, copy) NSString *bizaddress;
@property (nonatomic, copy) NSString *receiver_name;
@property (nonatomic, copy) NSString *receiver_address;
@property (nonatomic, copy) NSArray <ModelLabel *>*arrLabel;

+(instancetype)modelWithDict:(NSDictionary *)dict;

@end

.m
#import "ModelList.h"
@implementation ModelList

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

-(instancetype)initWithDict:(NSDictionary *)dict{
    if (self = [super init]) {
        [self setValuesForKeysWithDictionary:dict];
        NSMutableArray *arr = [NSMutableArray array];
        //取出Labels数组里面的数据转换成ModelLabel模型,如果是模型里面嵌套有其他模型，需要在这里调用其他模型的转模型方法
        NSArray *arrTemp = dict[@"Labels"];
        for (NSDictionary *dictTemp in arrTemp) {
            [arr addObject:[ModelLabel modelWithDict:dictTemp]];
        }
        self.arrLabel = [arr copy];
    }
    return self;
}

-(void)setValue:(id)value forUndefinedKey:(NSString *)key{
    
}

@end
