2. Details of File Upload using AFN

-(Void) uploadImage {/* if you need to modify this code segment, you can adjust the position 1. put upload. php is changed to the address provided by website developers. 2. change file to the field name notified by website developers * // AFN3.0 + the Handle Based on the blocked HTPPSession AFHTTPSessionManager * manager = [AFHTTPSessionManager manager]; NSDictionary * dict =@{ @ "username ": @ "Saup"}; // formData: Used to splice the data to be uploaded. A data body to be uploaded is generated at this location [manager POST: @ "http: // 192.168.1.111: 12345/upload. php "parameters: dict constructingBodyWithBlock: ^ (id <AFMultipartFormData> _ Nonnull formData) {UIImage * image = [UIImage imageNamed: @" moon "]; NSData * data = UIImagePNGRepresentation (image); // during network development, during file upload, the file cannot be overwritten, and the file name must be duplicated. // you need to solve this problem, // you can use the current system event as the file name NSDateFormatter * formatter = [[NSDateFormatter alloc] init] During upload; // you can set the time format formatter. dateFormat = @ "yyyyMMddHHmmss"; NSString * str = [formatter stringFromDate: [NSDate date]; NSString * fileName = [NSString stringWithFormat: @ "symbol @.png", str]; // upload/* This method parameter 1. [binary data] 2. the corresponding website [upload. [field "file"] 3. [file name] 4. [mimeType] */[formData appendPartWithFileData: data name: @ "file" fileName: fileName mimeType: @ "image/png"];} progress: ^ (NSProgress * _ Nonnull uploadProgress) {// upload progress // @ property int64_t totalUnitCount; total file size to be downloaded // @ property int64_t completedUnitCount; size of the downloaded file /// Add a listener for the Progress SS (@ "% f", 1.0 * uploadProgress. completedUnitCount/uploadProgress. totalUnitCount); // return to the main queue column to refresh the UI. The custom progress bar is dispatch_async (dispatch_get_main_queue (), ^ {self. progressView. progress = 1.0 * uploadProgress. completedUnitCount/uploadProgress. totalUnitCount;});} success: ^ (NSURLSessionDataTask * _ Nonnull task, id _ Nullable responseObject) {NSLog (@ "uploaded successfully % @", responseObject);} failure: ^ (NSURLSessionDataTask * _ Nullable task, NSError * _ Nonnull error) {NSLog (@ "Upload Failed % @", error);}];}

4. Check network status-optimize User Experience

-(Void) viewDidLoad {[super viewDidLoad]; // Network Monitoring handle AFNetworkReachabilityManager * manager = [AFNetworkReachabilityManager sharedManager]; // you need to monitor the network connection status, you must first call the startMonitoring method of the Singleton [manager startMonitoring]; [manager setReachabilityStatusChangeBlock: ^ (AFNetworkReachabilityStatus status) {// status: // response =-1, unknown // AFNetworkReachabilityStatusNotReachable = 0, not connected // required = 1, 3G // AFNetworkReachabilityStatusReachableViaWiFi = 2, wireless connection NSLog (@ "% d", status);}];}
