首先看看代码
@property (nonatomic,strong) NSString *id;
@property (nonatomic,strong) NSString *screen_name;
@property (nonatomic,strong) NSString *url;
@property (nonatomic,strong) NSString *mid;
@property (nonatomic,strong) NSString *from;
@property (nonatomic,strong) NSString *created_at;
@property (nonatomic,strong) NSString *text;
@property (nonatomic,strong) NSString *type;
@property (nonatomic,strong) NSString *name;
@property (nonatomic,strong) NSString *user_id;
@property (nonatomic,strong) NSString *width;
@property (nonatomic,strong) NSString *height;
@property (nonatomic,strong) NSString *tag;
@property (nonatomic,strong) NSString *profile_image;
@property (nonatomic,strong) NSString *image1;
@property (nonatomic,strong) NSString *image2;
@property (nonatomic,strong) NSString *image0;属性很多。手工写setvalue太麻烦
+ (instancetype)picinfo:(NSDictionary *)dict
{
PicModel *picmodel = [[self alloc] init];
[picmodel setValuesForKeysWithDictionary:dict];
return picmodel;
}
单纯的运行setValuesForKeysWithDictionary是必然core的这时只需要重写- (void)setValue:(id)value forUndefinedKey:(NSString *)key 方法即可
- (void)setValue:(id)value forUndefinedKey:(NSString *)key {
if([key isEqualToString:@"id"])
self.userid = value;
}并把声明 中的id改为userid
@property (nonatomic,strong) NSString *userid;这样一来执行程序快速，还省去了不少手工代码。
