如何在 ios 应用扩展中使用 AFNetworking 上传？
苹果的例子使用了 NSURLSession，你能解释一下它是如何工作的吗？
- (void)didSelectPost {
NSExtensionItem *imageItem = [self.extensionContext.inputItems lastObject];
// Verify that we have a valid NSExtensionItem
if (!imageItem) {
return;
}
// Verify that we have a valid NSItemProvider
NSItemProvider *imageItemProvider = [[imageItem attachments] firstObject];
if (!imageItemProvider) {
return;
}
// Look for an image inside the NSItemProvider
if ([imageItemProvider hasItemConformingToTypeIdentifier:(NSString *)kUTTypeImage]) {
[imageItemProvider loadItemForTypeIdentifier:(NSString *)kUTTypeImage options:nil completionHandler:^(id item, NSError *error) {
if (item)
{
NSData *data = [NSData dataWithContentsOfURL:item];
[self method:data];
}
[self.extensionContext completeRequestReturningItems:nil completionHandler:nil];
}];
}
}
如何使用此方法或使用 AFNetworking 或使用我的应用程序上传此数据？
- (void)method:(NSData *)data
{
NSString *confName = @"com.example.photoblog.backgroundconfiguration";
NSURLSessionConfiguration *conf = [NSURLSessionConfiguration backgroundSessionConfiguration:confName];
NSURLSession *session = [NSURLSession sessionWithConfiguration:conf delegate:self delegateQueue:nil];
NSURLRequest *requeust = [self requestForExtensionItems];
NSURLSessionUploadTask *upload = [session uploadTaskWithStreamedRequeust:request];
[upload resume];
}
