很多小伙伴都会遇到这样的问题，在定义model时，要自己写很多的属性，如果碰到属性特别多的时候，只能一个一个慢慢写了，很是麻烦。下面给大家一个简单的属性生成器代码：

// 自动生成属性声明的代码+ (void)propertyCodeWithDictionary:(NSDictionary *)dict{NSMutableString *strM = [NSMutableString string];[dict enumerateKeysAndObjectsUsingBlock:^(id  _Nonnull key, id  _Nonnull obj, BOOL * _Nonnull stop) {NSString *str;NSLog(@"%@",[obj class]);if ([obj isKindOfClass:NSClassFromString(@"__NSCFString")] || [obj isKindOfClass:NSClassFromString(@"NSTaggedPointerString")] || [obj isKindOfClass:NSClassFromString(@"__NSCFConstantString")]) {str = [NSString stringWithFormat:@"@property (nonatomic, copy) NSString *%@;",key];}if ([obj isKindOfClass:NSClassFromString(@"__NSCFNumber")]) {str = [NSString stringWithFormat:@"@property (nonatomic, assign) int %@;",key];}if ([obj isKindOfClass:NSClassFromString(@"__NSCFArray")]) {str = [NSString stringWithFormat:@"@property (nonatomic, copy) NSArray *%@;",key];}if ([obj isKindOfClass:NSClassFromString(@"__NSCFDictionary")]) {str = [NSString stringWithFormat:@"@property (nonatomic, copy) NSDictionary *%@;",key];}if ([obj isKindOfClass:NSClassFromString(@"__NSCFBoolean")]) {str = [NSString stringWithFormat:@"@property (nonatomic, assign) BOOL %@;",key];}[strM appendFormat:@"\n%@\n",str];}];NSLog(@"%@",strM);}

使用起来也很简单，就是写一个NSObiect的Categorty, 里面写入上述方法即可！

在网络请求的返回中，直接调用该方法，实现属性列表输出，如下所示：

@property (nonatomic, assign) int instalmentPeriods;@property (nonatomic, copy) NSString *thumbnailUrl;@property (nonatomic, assign) int goodsStatus;@property (nonatomic, assign) int goodId;@property (nonatomic, copy) NSString *goodTitle;@property (nonatomic, copy) NSString *goodsCode;@property (nonatomic, assign) int openType;@property (nonatomic, assign) int brandId;@property (nonatomic, assign) int originalPrice;@property (nonatomic, assign) int bannerId;@property (nonatomic, assign) int directPaymentAmount;@property (nonatomic, assign) int peroidInstalmentAmount;@property (nonatomic, copy) NSString *goodsName;@property (nonatomic, assign) int goodsOrder;

是不是感觉很爽，再也不用一个一个手输了，哈哈。。。
