IOS how to POST GET DELETE PUT Rest Api

Question

我正在构建连接到Rest API的应用程序，到目前为止，我只使用以下代码发出了GET请求：

//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];
}

此代码仅适用于GET请求。我看到有很多框架（例如RestKit…）。但我对其他请求有点不知所措！那么，对IOS应用程序发出POST DELETE PUT请求的最佳解决方案是什么呢？

这是类似的代码，但使用了类NSMutableRequest。您可以设置httpbody和其他参数来与服务器通信。

检查文档：https://developer.apple.com/library/mac/#documentation/Cocoa/Reference/Foundation/Classes/NSMutableURLRequest_Class/Reference/Reference.html

要发布某些内容，只需放置setHTTPMethod:@"post"并使用setHTTPBody:
