POWrapping success failure blocks from AFNetworking within a method
text
Body
copied!<p>I need to encapsulate the response from AFNetworking calls within my own method as I'm writing a library. This code gets me close:</p> <pre><code>MyDevice *devices = [[MyDevice alloc] init]; [devices getDevices:@"devices.json?user_id=10" success:^(AFHTTPRequestOperation *operation, id responseObject) { ... can process json object here ... } - (void)getDevices:(NSString *)netPath success:(void (^)(AFHTTPRequestOperation *operation, id responseObject))success failure:(void (^)(AFHTTPRequestOperation *operation, NSError *error)) failure { [[MyApiClient sharedDeviceServiceInstance] getPath:[NSString stringWithFormat:@"%@", netPath] parameters:nil success:success failure:failure]; } </code></pre> <p>However, I need to process the json object data returned from getPath before returning to getDevices(). I've tried this:</p> <pre><code>- (void)getDevices:(NSString *)netPath success:(void (^)(id myResults))success failure:(void (^)(AFHTTPRequestOperation *operation, NSError *error)) failure { [[MyApiClient sharedDeviceServiceInstance] getPath:[NSString stringWithFormat:@"%@", netPath] parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) { ... can process json object here ... } failure:^(AFHTTPRequestOperation *operation, NSError *error) { ... process errors here ... }]; } </code></pre> <p>But now there is no call back to getDevices(). So how do I process the json object in getDevices & have the block return on completion? Appreciate the help, as I'm new to blocks.</p>

Querying!
