ObjcModelValidationObjective-C 实现数据验证框架

ObjcModelValidation 灵感来自 Ruby ORM 框架的 ActiveRecord，实现了 Objective-C 的数据验证框架。

示例代码

Model：

#import "ValidationModel.h"



@interface SampleModel : ValidationModel



@property (nonatomic, strong) NSString *nameString;

@property (nonatomic, strong) NSNumber *ageNumber;



@end

使用方法：

#import "SampleModel.h"



@implementation SampleModel



-(NSError *)validateAgeNumber:(NSNumber *)ageNumber{

    if ([ageNumber greaterThan:@18] && [ageNumber presence]) {

        return nil;

    }



    return [self errorWithLocalizedMessage:NSLocalizedString(@"You should be older than 18.", @"")];

}



-(NSError *)validateNameString:(NSString *)nameString{

    if ([nameString lengthMin:4]) {

        return nil;

    }



    return [self errorWithLocalizedMessage:NSLocalizedString(@"Your name should be at least 4 characters long", @"")];

}



@end
