NSInteger bytesWritten = 0;
while ( imgData.length > bytesWritten )
{
while ( ! self.outputStream.hasSpaceAvailable )
[NSThread sleepForTimeInterval:0.05];
//sending NSData over to server
NSInteger writeResult = [self.outputStream write:[imgData bytes]+bytesWritten maxLength:[imgData length]-bytesWritten];
if ( writeResult == -1 )

bytesWritten += writeResult;

You are sending only imgData
您只发送
imgData
NSData *imgData = UIImageJPEGRepresentation(image, 0.2);
NSMutableData *completeData = [[NSMutableData alloc] initWithBytes:[stringData bytes] length:[stringData length]];
[completeData appendData:imgData];
NSInteger bytesWritten = 0;
while ( completeData.length > bytesWritten )
{
while ( ! self.outputStream.hasSpaceAvailable )
[NSThread sleepForTimeInterval:0.05];
//sending NSData over to server
NSInteger writeResult = [self.outputStream write:[completeData bytes]+bytesWritten maxLength:[completeData length]-bytesWritten];
if ( writeResult == -1 )
NSLog(@"error code here");
else
bytesWritten += writeResult;
}
