why not support NSDictionary as NSUserDefault about mmkv HOT 10 CLOSED

Mainly because NSDictionary's value type is uncertain, it's hard to encode/decode NSDictionary properly in protobuf, if not possible.

However, you can turn a NSDictionary into a NSData by NSArchive, and store that NSData in MMKV.

NSUserDefault can read/write NSDictionary directly, and MMKV needs to do a conversion through NSArchive. If you consider the consumption of conversion, is the performance advantage of MMKV still greater than NSUserDefault?

Well, NSUserDefault's NSDictionary support doesn't come in free. Which algorithm do you think it used to store NSDictionary? NSArchive? I haven't test it yet, but that's my best guess.

Given that guess, I have confidence MMKV will beat NSUserDefault in such case.

you tell me I should better convert dictionary or Nsarray to NSData ,not the jsonStr , the reason is ( value type is uncertain, it's hard to encode/decode NSDictionary properly)? when I conert to jsonStr , all is NSString ,
or have other reason ?

Use NSData for efficiency, or JSON for convenience. It's your choice.

其实可以提供一个直接存 NSDictionary 的 api。然后内部进行一步转换~你觉得呢？
