IOS how to POST GET DELETE PUT Rest Api - ios

Question

I am building my App conected to a Rest API and until now I only made a GET request with the following code :
//Start login process
NSString *emailstring = email.text;
NSString *passstring = pass.text;
// Create the URL from a string.
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:#"http://www.myserver.com/Rest/API/users?format=json&email=%#&password=%#",emailstring,passstring]];
NSLog(#"%#",url);
// Create a request object using the URL.
NSURLRequest *request = [NSURLRequest requestWithURL:url];
// Prepare for the response back from the server
NSHTTPURLResponse *response = nil;
NSError *error = nil;
// Send a synchronous request to the server (i.e. sit and wait for the response)
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSLog(#"Reponse from web:%#", response);
// Check if an error occurred
if (error != nil) {
NSLog(#"%#", [error localizedDescription]);
// Do something to handle/advise user.
UIAlertView *message = [[UIAlertView alloc] initWithTitle:#"Login error"
message:#""
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[message show];
}
else {
// Convert the response data to a string.
NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
// View the data returned - should be ready for parsing.
NSLog(#"%#", responseString);
// Add data to a Plist file for next time
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *path = [documentsDirectory stringByAppendingPathComponent:#"login.plist"];
NSArray *values = [[NSArray alloc] initWithObjects:emailstring,passstring,#"IDtest",nil];
[values writeToFile:path atomically:YES];
[values release];
[self dismissModalViewControllerAnimated:YES];
}
This code work fine just for a GET request. I saw it is there a lot of framework (e.g RestKit, ....). But I am getting a bit lost with other request ! So what is the best solution to make POST DELETE PUT request for an IOS App ?

It's similar code, but using the class NSMutableRequest. You can set the httpbody and other parameters to communicate with the server.
check the documentation: https://developer.apple.com/library/mac/#documentation/Cocoa/Reference/Foundation/Classes/NSMutableURLRequest_Class/Reference/Reference.html
to post something, just put setHTTPMethod:#"POST"and assign the data to post using setHTTPBody:
