sqlite3_column_blob will gives you NSDictionary in the form of NSData:
NSUInteger blobLength = sqlite3_column_bytes(statement, colNo);
NSData *data = [NSData dataWithBytes:sqlite3_column_blob(statement, colNo) length:blobLength];
NSDictionary *dictionary=[NSJSONSerialization
JSONObjectWithData: data
options:NSJSONReadingMutableLeaves
error:nil];
NSUInteger blobLength = sqlite3_column_bytes(statement, colNo);
NSData *data = [NSData dataWithBytes:sqlite3_column_blob(statement, colNo) length:blobLength];
NSDictionary *dictionary=[NSJSONSerialization
JSONObjectWithData: data
options:NSJSONReadingMutableLeaves
error:nil];
