Question

I am trying to receive a jpeg image from my c# server. The weird thing is when I run it with the debugger and have a break point anywhere in the method it works perfectly fine. Without a breakpoint then I get this error

Corrupt JPEG data: premature end of data segment

Here is my code

(void)stream:(NSStream *)stream handleEvent:(NSStreamEvent)eventCode {
NSMutableData *data;
data = [NSMutableData new];
switch(eventCode) {
    case NSStreamEventHasBytesAvailable:
    {
        uint8_t buffer[1024];
        int len;

        while([inputStream hasBytesAvailable]) {
            len = [inputStream read:buffer maxLength:sizeof(buffer)];

            if (len > 0)
            {
                [data appendBytes:(const void*)buffer length:sizeof(buffer)];
            }
        }
        UIImage *images = [[UIImage alloc]initWithData:data];
        [dvdCover setImage:images];
    } break;
    case NSStreamEventEndEncountered:
    {
        //UIImage *images = [[UIImage alloc]initWithData:data];
        //[dvdCover setImage:images];


    } break;
}

}

hi you can check this code hop it will help you...

case NSStreamEventHasBytesAvailable:
{

uint32_t max_size = 1000000;  // Max size of the received imaged you can modify it as your reqirement.
        NSMutableData* buffer = [[NSMutableData alloc] initWithLength: max_size];
        NSInteger totalBytesRead = 0;
        NSInteger bytesRead = [(NSInputStream *)stream read: [buffer mutableBytes] maxLength: max_size];
        if (bytesRead != 0) {
            while (bytesRead > 0 && totalBytesRead + bytesRead < max_size) {
                totalBytesRead+= bytesRead;
                bytesRead = [(NSInputStream *)stream read: [buffer mutableBytes] + totalBytesRead maxLength: max_size - totalBytesRead];
            }
            if (bytesRead >= 0) {
                totalBytesRead += bytesRead;
            }
            else {
                // read failure, report error and bail (not forgetting to release buffer)
            }
            [buffer setLength: totalBytesRead];
            yourImageName.image = [UIImage imageWithData: buffer];
            [buffer release];

}  break;
