Is it possible to serialise a Realm Object into JSON?

Question

有谁知道Realm（iOS）中是否支持将RLMObject序列化为JSON以进行导出？

Answer 1

I don't believe there is any support officially, but this article may describe some other third party libraries which may be able to achieve what you are after

Answer 2

It should work like with any other objects:

NSData *jsonData = [NSJSONSerialization dataWithJSONObject:realmObject options:NSJSONWritingPrettyPrinted error:&writeError];
NSString *jsonString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding]; 

But:

An object that may be converted to JSON must have the following properties:

The top level object is an NSArray or NSDictionary.

• All objects are instances of NSString, NSNumber, NSArray, NSDictionary, or NSNull.

• All dictionary keys are instances of NSString.

• Numbers are not NaN or infinity.
