I have server at the java and application client at iphone. I can send list of online user at application client. All right, but function stringWithUTF8String can read user name or return nil.




Server code for send message


int lenUsersName = NameUsers.length;
byte[][] names = new byte[lenUsersName][];
int len = 5;
for (int i = 0; i < lenUsersName; i++) {
byte[] name = NameUsers.getBytes();
len += name.length + 4;
names = name;
}
ioBuffer = IoBuffer.allocate(len, false);
ioBuffer.put((byte) serverTypeMessage.ordinal());
ioBuffer.putInt(lenUsersName);
for (int i = 0; i < lenUsersName; i++) {
ioBuffer.putInt(names.length);
ioBuffer.put(names);
}
break;

Client code

- (void)stream:(NSStream *)stream handleEvent:(NSStreamEvent)eventCode {




switch (eventCode) {

case NSStreamEventHasBytesAvailable:

{

NSMutableData *data = [[NSMutableData alloc] init];




NSInputStream *inputStream = (NSInputStream *) stream;

while ([inputStream hasBytesAvailable]) {

uint8_t buf[1024];

NSInteger len = [inputStream read:buf maxLength:1024];

if (len > 0) {

[data appendBytes:(const void *) buf length:(NSUInteger) len];

}

}

ServerMessage *mess = [[ServerMessage alloc] initWithInputData:data];

[data release];




if (CallBackObject != nil && CallBackFunc != nil) {

[CallBackObject performSelector:CallBackFunc withObject:mess];

}

[mess autorelease];

}

break;

}

}

- (void)PlayerListParse:(const char *)temp {

uintptr_t offset = 1;

int lenUsersName = OSReadBigInt32(temp, offset);

offset += 4;

self.NameUsers = [[[NSMutableArray alloc] init] autorelease];

for (int i = 0; i < lenUsersName; i++) {

int lenName = OSReadBigInt32(temp, offset);

offset += 4;

const char *temp1 = temp + offset;

NSString *name = nil;

do {

name = [[NSString stringWithUTF8String:temp1] retain];

} while (name == nil);

offset += lenName;

[NameUsers addObject:name];

[name release];

}

}




- (id)initWithInputData:(NSData *)data {

self = [super init];

if (self) {

MessageData = [data retain];

NSLog(@"ServerMessage initWithInputData data=%@ len=%d", data, [data length]);

const char *temp = (const char *) [data bytes];

serverTypeMessage = (enum ServerTypeMessage) temp[0];

switch (serverTypeMessage) {

case ListPlayersServerTypeMessage:

NSLog(@"ServerMessage ListPlayersServerTypeMessage");

[self PlayerListParse:temp];

break;

}

}

return (self);

}




do.. while - this is little save the situation, but i don't think what that good idea.

Help to understand what is wrong?

p.s: sometimes a function returns wrong string, but message from server in bytes is identical.
