nsurlconnection

i have set up a nsurl which grabs the data from http. when i run instrument, it says i have a leak NSFNetwork object. and how do i release theConnection in (void)ButtonClicked? or it will be release later on? - (void)ButtonClicked { NSURLRequest *theRequest = [NSURLRequest requestWithURL:[NSURL URLWithString:KmlUrl] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:20.0f]; NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; if (theConnection) { // receivedData is declared as a method instance elsewhere NSMutableData *receivedData =

I was looking at the NSURLConnection class which could be used to establish a sync or async connection to an URL and then retrieve its data... a lot of changes have been made to this class with IOS 5 and I've seen they introduced some formal protocols related to authentication or download, but I don't see, for example, if the connection:didReceiveResponse: message (that was previously sent to the delegate and that it is no more available) is still available in some protocols.. How do you implement an async connection and retrieve, for example, HTTP headers as soon as the Response is received?

Ok, I've got a UITableView with custom UITableViewCell s that each contain a UIImageView whose images are being downloaded asynchronously via an NSURLConnection . All pretty standard stuff... The issue is, when the table scrolls, the new images are downloaded in the background correctly but not RENDERED until the table stops moving. How do I get the table to render it's content even when it's moving? Thanks. -- UPDATE -- After a closer look, I'm finding that the NSURLConnection delegate methods aren't firing until the table stops scrolling. Not sure why. Any help would be great. The reason the

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { response=[[NSString alloc]initWithData:data encoding:NSUTF8StringEncoding];} Here, I get the response in the "response value" --> [{"response":true,"danger":false}] The thing is: How can I rescue the "danger"(true/false) into a new variable to use it in other methods? I need to know if "danger" is true or false becouse if its true, i have to show an alert. I would really appreciate someone help, as I am stuck in here. use NSJSONSerialization: http://developer.apple.com/library/ios/#documentation/Foundation

This is what I have in a public method - (IBAction)methodName NSString *quoteNumber = [[self textBox] text]; NSURL *url = [[NSURL alloc] initWithString:@"http://TestSite.com/virdirectory/Webservice1/Service1.asmx/GetQuote?number=%d", quoteNumber]; The error I get is: Too many arguments to method call, expected 1, have 2 What am I doing wrong? Max The initWithString method can only accept a normal NSString, you are passing it a formatted NSString, Take a look at this code: NSURL *url = [[NSURL alloc] initWithString:[NSString stringWithFormat:@"http://TestSite.com/virdirectory/Webservice1

I am pulling down a plist from a URL using an NSURLConnection, which returns an NSData object. I would like to convert this to an NSArray. Can anyone help me? I am refactoring a method that currently does a synchronous request to the URL, using arrayWithContentsOfURL: to get the NSArray. Thanks!! Use +[NSPropertyListSerialization dataWithPropertyList:format:options:error:] to convert the data, then check if the result -isKindOfClass:[NSArray class] . Use NSKeyedArchiver for archiving object to data. NSKeyedUnarchiver for unarchiving object from data: NSArray *object = [NSKeyedUnarchiver

I am using the code below to check for an internet connection. It was working correctly but after the Swift 2.0 update I now see an error on the line var data = NSURLConnection.sendSynchronousRequest(request, returningResponse: &response, error: nil) as NSData? saying extra argument 'error' in call. class func isConnectedToNetwork()->Bool{ var Status:Bool = false let url = NSURL(string: "http://google.com/") let request = NSMutableURLRequest(URL: url!) request.HTTPMethod = "HEAD" request.cachePolicy = NSURLRequestCachePolicy.ReloadIgnoringLocalAndRemoteCacheData request.timeoutInterval = 10.0

I've read through tons of messages saying the same thing all over again : when you use a NSURLConnection, delegate methods are not called . I understand that Apple's doc are incomplete and reference deprecated methods, which is a shame, but I can't seem to find a solution. Code for the request is there : // Create request NSURL *urlObj = [NSURL URLWithString:url]; NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:urlObj cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:30]; [request setValue:@"gzip" forHTTPHeaderField:@"Accept-Encoding"]; if (![NSURLConnection

I am having a hard time to find any examples for NSURLConnection delegate method implementations. I want to send data with a HTTP post with a button click. Not sure how to make a "submitting" screen and "submitted". (I know how to use spinner and will use them) I am using this code under a botton click action, but unable to use any delegate stuff. Not sure how to implement them with my current set up. NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL: [NSURL URLWithString:@"http://myURL.com"]]; [request setHTTPMethod:@"POST"]; NSString *postString = [wait
