将字符串类型数组存储在RealM目标c中 [英] Store string type array in RealM objective c

问题描述

我想将数组的字符串类型存储在领域目标c 中.

i want to store string type of array in Realm objective c.

Ex数组:- 的 [ 58575bc922e87bd14480132f"， 58575c5c22e87bd144801331"， 58575cc922e87bd144801333"， 58575d5b22e87bd144801335"， 58575bc922e87bd14480132f"， 58575c5c22e87bd144801331"， 58575cc922e87bd144801333"， 58575d5b22e87bd144801335"， 58575bc922e87bd14480132f"， 58575c5c22e87bd144801331"， 58575cc922e87bd144801333"，58575d5b22e87bd144801335 ]

推荐答案

您可以从RLMObject类继承，并将NSString作为属性放入您的RLMObject中. 然后，您可以再次使用以前制作的RLMObject的RLMArray来制作新的RLMObject.

You can inherit from RLMObject class and put the NSString into your RLMObject as a property. Then you can make new RLMObject one more time, with a RLMArray of previously made RLMObject now.

@interface StringObject: RLMObject
@property NSString *stringValue;
@end

@interface RealmObject: RLMObject
@property RLMArray<StringObject> *realmArray
@end

进行此操作后，可以随时使用它. F.e.使用快速枚举循环将字符串放入RLMArray领域.

After this manipulation feel free to use it. F.e. use fast enumeration loop to put the strings into realm RLMArray.

NSArray *arrayOfStrings = @[@"58575bc922e87bd14480132f",@"58575c5c22e87bd144801331",@"58575cc922e87bd144801333",@"58575d5b22e87bd144801335",@"58575bc922e87bd14480132f",@"58575c5c22e87bd144801331",@"58575cc922e87bd144801333",@"58575d5b22e87bd144801335",@"58575bc922e87bd14480132f",@"58575c5c22e87bd144801331",@"58575cc922e87bd144801333",@"58575d5b22e87bd144801335"];

RLMRealm *realm = [RLMRealm defaultRealm];

RealmObject *realmObject = [RealmObject new];
for (NSString *value in arrayOfStrings) {
    StringObject *string = [StringObject new];
    string.stringValue = value;

    [realmObject.realmArray addObject:string];
}

[realm beginWriteTransaction];
[realm addObject:realmObject];
[realm commitWriteTransaction];
