Hi all,
Am a beginner in objective C, i am implementing a
function that would query a web server and display the returning string in console. I am calling the
function (getDatafromServer) repeatedly in a loop. The problem is that the first time am getting the value whereas the other times, it returns me a (null) in console... I've searched about memory management and check out on the forums but none have worked. Can you please guys tell me where am wrong in the codes below? Thanks in advance....
@implementation RequestThread
+(void)startthread:(id)param{
while (true) {
//NSLog(@"Test threads");
sleep(5);
NSLog(@"%@",[self getDatafromServer]);
}
}
+(NSString *) getDatafromServer{
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
NSString *myRequestString = @"name=Hello%20&
[email protected]";
NSData *myRequestData = [NSData dataWithBytes:[myRequestString UTF8String] length:[myRequestString length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL: [NSURL URLWithString:@"http://192.168.1.32/gs/includes/widget/getcalls.php?user=asdasd&passw=asdasdasd"]];
[request setHTTPMethod:@"POST"];
[request setHTTPBody: myRequestData];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"content-type"];
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *myString = [NSString stringWithUTF8String:[returnData bytes]];
[myRequestString release];
[request release];
[returnData release];
return myString;
[pool release];
}
@end
