Exception handling

[t0lkman]

Can you post some examples how to handle exceptions?

let say you do
[RFService execRequest:r completion:^(RFResponse *response) {

but server is not available or the document is not found (404)

You'll just need to check RFResponse's error property:

/*!

• @Property error
• @abstract This propery will hold NSError if one occurs during request. NULL if there's no error
  /
  @Property (nonatomic, readonly, retain) NSError error;

This property will contain the NSError in case something goes wrong.
For HTTP errors you can also check the httpCode property of RFResponse:

/*!

• @Property httpCode
• @abstract HTTP code RESTful service returned (e.g. 200, 404, 400, 500 etc...)
  */
  @Property int httpCode;

basically you'd do something like

[RFService execRequest:r completion:^(RFResponse *response) {
if (response.error) {
//there's an error, handle it
return;
}
if (response.httpCode == 200) {
//all good
} else {
//check your status
}
}]

I'll update the README file with some examples and close this issue when I do...

Great, Thank you.
The wrapper looks promising :)

Just want to confirm, it's working!
How about additional headers? I want pass my custom user-agent http header
is there anyway?

Yeah, just use additionalHTTPHeaders property of RFRequest.

/*!

• @Property additionalHTTPHeaders
• @abstract Additional HTTP headers in form of key/value dictionary to include with the HTTP request
  /
  @Property (nonatomic, retain) NSDictionary additionalHTTPHeaders;

Just add key-value pairs to a NSDictionary and assign to this property.
