I am using Restkit in my iOS app to make a GET call to my server. I am able to get the call to work just fine, except that it is supposed to be asynchronous and it is blocking my main thread. I am basically using their exact sample to make the request from their github page which is as follows:
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://mywebapi.com/Article"]];
RKObjectRequestOperation *operation = [[RKObjectRequestOperation alloc] initWithRequest:request responseDescriptors:@[responseDescriptor]];
[operation setCompletionBlockWithSuccess:^(RKObjectRequestOperation *operation, RKMappingResult *result) {
Article *article = [result firstObject];
NSLog(@"Mapped the article: %@", article);
} failure:^(RKObjectRequestOperation *operation, NSError *error) {
NSLog(@"Failed with error: %@", [error localizedDescription]);
}];
[operation start];
This blocks all main thread executions (such as my transitions) until the success block is called. Wrapping this call inside of a dispatch_queue does resolve the issue, but it is my understanding that this method is supposed to be asynchronous on its own.
Am I missing some configuration on the RKObjectRequestOperation, or is there a different method I should be calling for an async call?
I found the answer to this question here:
Basically, you do need to add it to an NSOperationQueue, otherwise it will run the call on the main thread.
