I have an implementation of a RESTful API in a class called WebServices. I call methods in this class from other classes within my app and would like to perform actions upon successful completion of a web service. I have a completion block as a part of my method headers, but am not sure if I am using them correctly as the app never seems to reach inside the completion part of the method call. This is how I am calling my method:
[services callUnregisterForPushNotifications:savedAccessToken pushToken:savedPushToken completionBlock:^(NSMutableArray *resultsArray) {
NSLog(@">>> COMPLETE! <<<");
[self.loadingView removeFromSuperview];
}];
And the method I am calling looks like this:
- (void)callUnregisterForPushNotifications:(NSString *)accessToken
pushToken:(NSString *)pushToken
completionBlock:(void (^)(NSMutableArray *resultsArray))completion{
NSLog(@"UNREGISTER FOR PUSH CALLED!");
NSLog(@"PUSH TOKEN %@", pushToken);
NSString *appendUrl = @"alerts/unregisterpush/";
NSLog(@"APPEND URL %@",appendUrl);
NSURL *unregisterUrl = [NSURL URLWithString:[NSString stringWithFormat:@"%@%@", BaseURLString, appendUrl]];
NSLog(@"UNREGISTER URL: %@",unregisterUrl);
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:unregisterUrl
cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:30.0];
[request setHTTPMethod:@"PUT"];
NSString *appendToken = [NSString stringWithFormat:@"Bearer %@", accessToken];
NSLog(@"TOKEN: %@",appendToken);
[request addValue:appendToken forHTTPHeaderField:@"Authorization"];
[request addValue:@"application/json, text/plain, */*" forHTTPHeaderField:@"Accept"];
[request addValue:@"application/json;charset=UTF-8" forHTTPHeaderField:@"Content-Type"];
NSString *postString = [NSString stringWithFormat:@"{"Guid":"%@"}",pushToken];
NSLog(@"POST STRING: %@",postString);
[request setHTTPBody:[postString dataUsingEncoding:NSUTF8StringEncoding]];
NSLog(@"REQUEST %@",request);
[NSURLCoection sendAsynchronousRequest:request
queue:[NSOperationQueue mainQueue]
completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) {
NSLog(@"UNREGISTER PUSH NOTIFICATIONS RESPONSE: %@", response);
NSLog(@"UNREGISTER PUSH NOTIFICATIONS ERROR: %@", error);
NSLog(@"UNREGISTER PUSH NOTIFICATIONS DATA: %@", data);
NSData *_data = data;// ... whatever
NSMutableString *_string = [NSMutableString stringWithString:@""];
for (int i = 0; i < _data.length; i++) {
unsigned char _byte;
[_data getBytes:&_byte range:NSMakeRange(i, 1)];
if (_byte >= 32 && _byte < 127) {
[_string appendFormat:@"%c", _byte];
} else {
[_string appendFormat:@"[%d]", _byte];
}
}
NSLog(@"UNREGISTER PUSH RESPONSE: %@", _string);
id obj= [NSJSONSerialization JSONObjectWithData:data options:0 error:&error];
if (!obj) {
//NSLog(@"REGISTER PUSH NOTIFICATIONS ERROR: %@", error);
} else {
//NSLog(@"REGISTER PUSH NOTIFICATIONS DATA: %@", obj);
//self.accessToken = [obj valueForKey:@"access_token"];
//NSLog(@"ACCESS TOKEN: %@",self.accessToken);
}
}];
}
Any advice / input would be appreciated, thanks in advance!
