AFN How to upload files

{

//1. Create a manager

Afhttprequestoperationmanager *mgr = [Afhttprequestoperationmanager manager];

//2. Send Request

[Mgr POST:@ "http://localhost/upload/upload.php" parameters:nil constructingbodywithblock:^ ( ID<AFMultipartFormData> formData) {

//FormData: Set the parameters required to upload the file , two ways to upload :

//<1> upload via URL of local file

{

NSString *fromfile = @ "/users/likaining/desktop/meinv.jpg";

Nsurl *url = [Nsurl urlwithstring:@ "file:///Users/likaining/Desktop/meinv.jpg"];

//URL: file path to upload files

//Name: The file name received by the server .

//FileName: The name of the file saved in the server

///MimeType: file type

[FormData appendpartwithfileurl:url Name:@ "UserFile" fileName:@ "MEINV" mimeType:@ "Image/jpg" error:NULL];

}

//<2> upload binary data via file

{

NSData *data = [NSData datawithcontentsoffile:zipfile];

[FormData appendpartwithfiledata:data Name:@ "UserFile" fileName:@ "Meinv.zip" mimeType:@ "gzip" ];

}

} success:^ (Afhttprequestoperation *operation, ID responseobject) {

// callback after successful upload

NSLog (@ "%@", responseobject);

} failure:^ (Afhttprequestoperation *operation, Nserror *error) {

// callback after upload failed

NSLog (@ " failed ");

}];

1. AFN monitoring network status

{

// Create network Status Manager

Afnetworkreachabilitymanager *mgr = [Afnetworkreachabilitymanager Sharedmanager];

// monitor changes in network status

[Mgr setreachabilitystatuschangeblock:^ (afnetworkreachabilitystatus status) {

// Call this block when the network status changes

switch (status) {

case Afnetworkreachabilitystatusreachableviawifi:

NSLog (@ "WiFi network ");

break;

case Afnetworkreachabilitystatusreachableviawwan:

NSLog (@ " cellular network ");

break;

case afnetworkreachabilitystatusnotreachable:

NSLog (@ " no network ");

break;

case Afnetworkreachabilitystatusunknown:

NSLog (@ " Unknown network ");

break;

default:

break;

}

}];

// start monitoring

[Mgr Startmonitoring];

}

2.reachability monitoring network status

{

// register to notify the viewer, when the network status changes , receive notifications !

[[Nsnotificationcenter Defaultcenter] Addobserver:self selector:@selector( internetstatuschanged) Name:kreachabilitychangednotification object:nil];

// when the controller is destroyed , remove the Notify Viewer .

-(void) Dealloc

{

[[Nsnotificationcenter Defaultcenter] Removeobserver:self];

}

// depending on the current network status , make a different response .

-(void) internetstatuschanged

{

NSLog (@ " network status changed ");

if ([reachability reachabilityforlocalwifi].currentreachabilitystatus = = Reachableviawifi) {

NSLog (@ "WiFi network ");

}

if ([reachability reachabilityforinternetconnection].currentreachabilitystatus = = Reachableviawwan) {

NSLog (@ " cellular network ");

}

if ([reachability reachabilityforinternetconnection].currentreachabilitystatus = = notreachable)

{

NSLog (@ " no network ");

}

}

// Create reachability objects and start monitoring changes in network status

-(void) Monitorinternetstatus

{

reachability *czreachability = [reachability reachabilityforinternetconnection];

[Czreachability Startnotifier];

self. reachability = czreachability;

}

-(void) Touchesbegan: (Nsset *) touches withevent: (Uievent *) event

{

[self monitorinternetstatus];

}

}
