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
