本文介绍了TableView在不同数据结构下（NSArray-NSDictionary-NSArray与NSArray-NSDictionary）如何从plist文件加载Model层数据的方法。通过具体实现代码展示了如何将字典数据转化为对象，并构建完整的数据模型。

TableView中Model层数据

一、如果plist文件中的形式：NSArray —> NSDictionary —>NSArray

最外层的字典

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

- (instancetype)initWithDict:(NSDictionary *)dict
{
    self = [super init];
    [self setValue:dict[@"title"] forKey:@"title"];
    self.carGroups = [SUNCar carsWithArray:dict[@"cars"]];
    return self;
}

+ (NSArray *)carGroups
{
    NSArray *array = [NSArray arrayWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"cars_total.plist" ofType:nil]];
    NSMutableArray *arrayM = [NSMutableArray array];
    for (NSDictionary *dict in array) {
        [arrayM addObject:[self carGroupsWithDict:dict]];
    }
    return arrayM;
}

最里层的数组

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

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

+ (NSArray *)carsWithArray:(NSArray *)array
{
    NSMutableArray *arrayM = [NSMutableArray array];
    for (NSDictionary *dict in array) {
        [arrayM addObject:[self carWithDict:dict]];
    }
         return arrayM;
}

二、如果plist文件中的形式：NSArray —> NSDictionary

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

+ (NSMutableArray *)tgs
{
    NSArray *array = [NSArray arrayWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"tgs.plist" ofType:nil]];

    NSMutableArray *arrayM = [NSMutableArray array];
    for (NSDictionary *dict in array) {
        [arrayM addObject:[self tgWithDict:dict]];
    }
    return arrayM;
}
