如何将元素数组从iOS发送到PHP webservice

I want to send array of <Full name, Email> pairs to my php webservice. Should I use NSMutable array of dictionaries? What is the proper way?

Update:

I want to send in JSON.

If it's going to be JSON formatted data use dictionaries. Look into AFNetworking library which handles all of your networking calls asynchronously for you.

Use this logic:

NSDictionary *dic = [NSDictionary dictionaryWithObject:yourDictionary/Array forKey:@"yourkeyForWebServiceFile"];
                SBJsonWriter *json=[[SBJsonWriter alloc] init];
                NSString *jsonStr = [json stringWithObject:dic];

now send this jsonStr in your PHP file as Post request. I have used SBJson library in this you can use others also.

You can just pass dictionary as parameters so that your php script grabs those parameters with $_POST variable.

I will post a sample code which uses AFNetworking library.

NSArray *keys = [NSArray arrayWithObjects: @"key1", @"key2", nil];
NSArray *values = [NSArray arrayWithObjects: @"value1", @"value2", nil];
NSDictionary *parameters = [NSDictionary dictionaryWithObjects: values Keys: keys];

AFHTTPClient *client = [[AFHTTPClient alloc] initWithBaseURL[NSURL URLWithString:@"Your  server url"];
NSURLRequest *request = [client requestWithMethod:@"POST" path:@"path" parameters:parameters];

AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {
} failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) {
}];
[operation start];

AFNetworking class takes care of everything for you. Generally, it is better to enqueue these operations in a NSOperationQueue. Hope that helps!
