Fwd: Apache Thrift iOS Client cannot get data from Play server

[Dylan Yang <dy...@point.io>]

This is my Thrift IDL i generated used for Cocoa,Python and Scala
Playframework,

namespace scala point.io.thrift
service ProcessTypesThrift {
    string getProcessTypes();}

For the server side, i use Scrooge and Finagle to generate native Thrift
Scala code and use Play framework build a Thrift server written by Scala.
For the client side, the Thrift code is generated by native Thrift code
generator, and i use cocoa and python to build clients for test. The result
is that python client can get the response from the Play server to make
sure the server is running properly. However, the cocoa client cannot get
any response from the server, and throws exceptions as follows.

Here is my cocoa code:

ProcessTypesThriftClient *server;
    NSLog(@"This is the log info: ...");
    TSocketClient *transport = [[TSocketClient alloc]
initWithHostname:@"localhost" port:9091];
    NSLog(@"Complete init *transport");
    TBinaryProtocol *protocol = [[TBinaryProtocol alloc]
initWithTransport:transport strictRead:YES strictWrite:YES];
    NSLog(@"Complete init *protocol");
    server = [[ProcessTypesThriftClient alloc] initWithProtocol:protocol];
    NSLog(@"Complete init server");
    NSLog(@"Receiving data...");
    NSString *str = [server getProcessTypes];    // receive data
    NSLog(@"Complete received data");
    NSLog(@"str%@",str);
    NSLog(@"done!");

And this is the exception as listed:

I use xcode 6.1 and Thrift 0.9.1 to running my cocoa project. Anybody could
point out how to solve this problem would appreciate.
