安裝

By far, the easiest way to integrate this library in your project is by using CocoaPods.

  1. Have Cocoapods installed, if you're not already

  2. In your Podfile, add the line 

    pod 'Objective-LevelDB'

  3. Runpod install

  4. Add thelibc++.dylibFramework to your project.
  5. Make something awesome.

How to use

Creating/Opening a database file on disk 

LevelDB *ldb = [LevelDB databaseInLibraryWithName:@"test.ldb"];
Setup Encoder/Decoder blocks 
ldb.encoder = ^ NSData * (LeveldBKey *key, id object) {
  // return some data, given an object
}
ldb.decoder = ^ id (LeveldBKey *key, NSData * data) {
  // return an object, given some data
}

NSMutableDictionary-like API 
[ldb setObject:@"laval" forKey:@"string_test"];
NSLog(@"String Value: %@", [ldb objectForKey:@"string_test"]);

[ldb setObject:@{@"key1" : @"val1", @"key2" : @"val2"} forKey:@"dict_test"];
NSLog(@"Dictionary Value: %@", [ldb objectForKey:@"dict_test"]);
