Eğer AFNetworking kullanımı hakkında size gerektiğini düşündüm yoksa. Web servisleri ile uğraşmayı çok daha kolaylaştırıyor. Yapmak istediğini düşündüğüm şeye benzer bir şey yaptım. Ağ isteklerini kapatmak için özel bir sınıf yazdım. Al bakalım: NetworkClient.h

bu bazıları benim yaptığım özeldir. Tüm web hizmetlerim güvenliği artırmak için bir APIKey kullanıyor ve tüm istekleri işlemeye başlamadan önce güvenlik kontrolleri yapıyorlar. Ağ istemcisi, web hizmetinin ne döndüğüne (JSON) bağlı olarak bir NSDictionary veya NSArray döndürür.
görüntü aktarma özelliğini kullanmak için, size
NSData *imageData = UIImagePNGRepresentation(myImage);
NSString *fileName = @"MyFileName.png";
NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:
@"Param1", @"Param1Name",
@"Param2", @"Param2Name",
@"Param3", @"Param3Name",
nil];
// Uses default URL
[NetworkClient processFileUploadRequestWithURL:nil

mimeType:@"image/png"
block:^(id obj) {
if ([obj isKindOfClass:[NSArray class]]) {
// Successful upload, do other processing as needed
