ios - CFNetwork internal error when load multiple images from local JSON file into tableview - 


- (uitableviewcell *)tableview:(uitableview *)tableview     cellforrowatindexpath:(nsindexpath *)indexpath {     static nsstring *cellidentifier = @"chatcell";     chatcell *cell = \[tableview dequeuereusablecellwithidentifier:@"mycell"\];      if (cell == nil)     {         \[tableview registernib:\[uinib nibwithnibname:cellidentifier bundle:nil\] forcellreuseidentifier:@"mycell"\];          cell = \[tableview dequeuereusablecellwithidentifier:@"mycell"\];     }      chatdata *chatdata = \[self.loadedchatdata objectatindex:\[indexpath row\]\];      \[cell.images sd_setimagewithurl:\[nsurl urlwithstring:@"http://dev.apppartner.com/apppartnerprogrammertest/images/justin_avatar.png,http://dev.apppartner.com/apppartnerprogrammertest/images/drew_avatar.png"\]placeholderimage:\[uiimage imagenamed:@"placeholder"\]\];     \[cell loadwithdata:chatdata\];      return cell; }

code

why getting cfnetwork internal error when try load multiple images local json file tableview?

it because url not found on server, mean url (http://dev.apppartner.com/apppartnerprogrammertest/images/justin_avatar.png,http://dev.apppartner.com/apppartnerprogrammertest/images/drew_avatar.png) wrong. if open url in browser throws error 404 the requested url /apppartnerprogrammertest/images/justin_avatar.png,http://dev.apppartner.com/apppartnerprogrammertest/images/drew_avatar.png not found on server. can try open url in browser. otherwise code seems alright. there no problem code think!!!

serialization - Convert Any type in scala to Array[Byte] and back -

i have following question: i have variable value in program declared value. i want convert value byte array.. how can serialize byte array , back? found examples related other types such double or int, not any. this should need. it's pretty similar how 1 in java. import java.io.{bytearrayinputstream, bytearrayoutputstream, objectinputstream, objectoutputstream} object serialization extends app { def serialise(value: any): array[byte] = { val stream: bytearrayoutputstream = new bytearrayoutputstream() val oos = new objectoutputstream(stream) oos.writeobject(value) oos.close stream.tobytearray } def deserialise(bytes: array[byte]): = { val ois = new objectinputstream(new bytearrayinputstream(bytes)) val value = ois.readobject ois.close value } println(deserialise(serialise("my test"))) println(deserialise(serialise(list(1)))) println(deserialise(serialise(map(1 -> 2)))) println(deserialise(seri
