很多小伙伴都會遇到這樣的問題，在定義model時枚赡，要自己寫很多的屬性，如果碰到屬性特別多的時候谓谦，只能一個一個慢慢寫了贫橙，很是麻煩。下面給大家一個簡單的屬性生成器代碼：
// 自動生成屬性聲明的代碼
+ (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);
}
使用起來也很簡答反粥， 就是寫一個NSObiect的Categorty, 里面寫入上述方法即可卢肃！
在網絡請求的返回中，直接調用該方法才顿，實現(xiàn)屬性列表輸出莫湘，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;
是不是感覺很爽，再也不用一個一個手輸了娜膘，哈哈逊脯。。竣贪。
