iPad/objective-C synchronous HTTP request example?
I can only find asynchronous iPad/objective C HTTP examples. How do I do a synchronous web request?
Agree with h4xxr and I would forward you to
Which is a fantastic lib that has robust HTTP request methods for both synch and asynch complete with code samples.
NSURLRequest * urlRequest = [NSURLRequest requestWithURL:aURL]; NSURLResponse * response = nil; NSError * error = nil; NSData * data = [NSURLConnection sendSynchronousRequest:urlRequest returningResponse:&response error:&error];
Depends on what data you're after. Something simple like this is synchronous, and is handy from time to time:
NSURL *url = [NSURL URLWithString:@"http://someaddress.asp?somedatarequest=1"]; NSArray *dataArray = [NSArray arrayWithContentsOfURL:url];
(Equivalent also exists for Dictionaries)
In this case, the system will wait for a response from someaddress.asp - therefore best perhaps to put something like this into a background thread.
If you have control over the format of the data at the other end, this can be a quick and easy way to get data into an iPhone/iPad app...
Edit - just wanted to state the obvious that typically asynchronous is usually best! No waiting around tying up system resources, especially if remote server has died etc... :)
