如何使用领域保存NSURL数组？

Question

Now, I have a realm model , including images, audios and others. So I have to get the URLs of the media files and give the model value of the URLs. But I meet a problem that I cannot save them into the realm. Because I can not save NSArray , also when I use the RLMArray to contain them ,it also don't be solved. So how can I give my model the URLs?

Answer 1

Its not possilbe to directly add the NSURL type in Realm but you can use workaround on your own like :-

@interface MyModel : JOBIBaseModel

@property (nonatomic, strong) NSString * urlString;

-(NSURL *)getUrl;

@end

@implementation MyModel

-(NSURL *)getUrl{
    return [NSURL URLWithString:self.urlString];
}

@end

Then access it from your object like:-

NSURL *url=Obj.getUrl;

Update for array

RLM_ARRAY_TYPE(MyArrayModel);
@interface MyArrayModel : JOBIBaseModel
@property (nonatomic, strong) NSString * urlString;
-(NSURL *)getUrl;
@end

@implementation MyArrayModel
-(NSURL *)getUrl{
    return [NSURL URLWithString:self.urlString];
}
@end

@interface MyModel : JOBIBaseModel
@property (nonatomic, strong) RLMArray <MyArrayModel> * strings;
@end

@implementation MyModel

@end

And use it like:-

NSURL *url=Obj.strings[0].getUrl;
