decode

问题 I have a 'User' object that contains a property of 'UIImage' class. How do I encode the image together with the other properties and save it in NSUserDefaults ? My understanding is that I can only encode NSString s? For example, currently in my code, I am adding the avatar_url (string) in the encode/decode implementation. How can I convert the url to UIImage and then encode it? - (void)encodeWithCoder:(NSCoder *)encoder { [encoder encodeObject:self.uid forKey:@"uid"]; [encoder encodeObject

问题 I'm currently working on an app that lets the user choose an MP3 audio file.

问题 I try to create a Pandas data-frame from a list of dictionaries: df = pandas.DataFrame(ls, columns = cols) As a result I get the following error message: UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 6: ordinal not in range(128) I assume that the errors is caused by the fact that some values of the dictionary contains "special characters" (like ä or ö ). How can I make pandas to accept these characters? 回答1: You need to ensure that your default encoding is set to

问题 I have captured RTP packets and need to decode the packets/sesssion with G.729.1 Decoder. In wireshark, I filtered the RTP packets, analyzed and saved the session as .raw file.

This is the point I am stuck: const Codec usedCodec = Codec.G7291; const int usedSampleRate = 8000; const int usedBitrate = 12200; var dec = new SpeechDecoder(); dec.SetCodec
