iOS -- 给model赋值时走了[self setValuesForKeysWithDictionary:dic]不走setvalue: forked:

这是一个小坑, 看看你的BaseModel的便利构造器的方法:

+ (__kindof BaseModel *)modelWithDic:(NSDictionary *)dic {    return [[self alloc] initWithDic:dic];}

self 一定要写成self, 这样才会调用子类的setvalue的方法. 不要写成BaseModel. 

 

BaseModel.m中的代码如下:

- (instancetype)initWithDic:(NSDictionary *)dic {    self = [super init];    if (self) {        [self setValuesForKeysWithDictionary:dic];    }    return self;}+ (__kindof BaseModel *)modelWithDic:(NSDictionary *)dic {    return [[self alloc] initWithDic:dic];}- (void)setValue:(id)value forUndefinedKey:(NSString *)key {    }- (id)valueForUndefinedKey:(NSString *)key {    return nil;}
