Posted at

すぐ忘れるのでここに記しておきます。

NSData to NSDictionary

//dicはNSDictionary型のオブジェクト
NSData *d = [NSKeyedArchiver archivedDataWithRootObject:dic];

NSDictionary to NSData

//dはNSData型のオブジェクト
NSDictionary *reverse = [NSKeyedUnarchiver unarchiveObjectWithData:d];

NSData to NSString

//dataはNSData型のオブジェクト
NSString *string = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];

NSString to NSData

//stringはNSString型
NSData *data = [string dataUsingEncoding:NSUTF8StringEncoding];
