Forming Communication Between Server and an iPhone application.

Question

hello all,

Is there any tutorial or blog or some documents which helps in learning how to communicate server from my iPhone application.

I just want to do a simple thing. Which is a page update.

Like I have a Label which needs to update to one particular name stored in my database and this database resides on a server.

So how to do this.

Answer 1

In the apple docs look at NSURLRequest/NSURLMutableRequest here http://developer.apple.com/iphone/library/documentation/Cocoa/Reference/Foundation/Classes/NSURLRequest_Class/Reference/Reference.html, this is the object you want to work with to achieve what you want. Youll set is URL, its connection properties, its httpMethod etc.

Your question has many answers and they all depend upon how you implement your server side. The path of least resistance is probably to create a web service that runs on top of a web server such as Apache. If you don't have the server side implemented as a web service, though, you could even create a web form and have the iPhone app create a POST request using NSMutableURLRequest that posts data to your form.

What have you done on the server side so far?

If you only need to display one value then you could do something very simple like:

[myLabel setText:[NSString stringWithContentsOfURL:[NSURL URLWithString:@"http://www.mywebsite.com/PageThatReturnsWhatYouWant"]]];
