The FBSDKGraphRequestConnectionDelegate protocol defines the methods used to receive network
activity progress information from a FBSDKGraphRequestConnection.
| Extends Protocol: | NSObject |
| Declared in: | FBSDKGraphRequestConnection.h |
requestConnection:didFailWithError:Tells the delegate the request connection failed with an error
| 매개변수 | 설명 |
|---|---|
connection | The request connection that successfully completed a network request |
error | The |
- (void) requestConnection: | (FBSDKGraphRequestConnection *)connection |
didFailWithError: | (NSError *)error; |
If the request connection fails with a network error then this method is called. The error
argument specifies why the network connection failed. The NSError object passed to the
FBSDKGraphRequestHandler block may contain additional information.
requestConnection:didSendBodyData:totalBytesWritten:totalBytesExpectedToWrite:Tells the delegate how much data has been sent and is planned to send to the remote host
| 매개변수 | 설명 |
|---|---|
connection | The request connection transmitting data to a remote host |
bytesWritten | The number of bytes sent in the last transmission |
totalBytesWritten | The total number of bytes sent to the remote host |
totalBytesExpectedToWrite | The total number of bytes expected to send to the remote host |
- (void) requestConnection: | (FBSDKGraphRequestConnection *)connection |
didSendBodyData: | (NSInteger)bytesWritten |
totalBytesWritten: | (NSInteger)totalBytesWritten |
totalBytesExpectedToWrite: | (NSInteger)totalBytesExpectedToWrite; |
The byte count arguments refer to the aggregated FBSDKGraphRequest objects, not a particular FBSDKGraphRequest.
Like NSURLConnection, the values may change in unexpected ways if data needs to be resent.
requestConnectionDidFinishLoading:Tells the delegate the request connection finished loading
| 매개변수 | 설명 |
|---|---|
connection | The request connection that successfully completed a network request |
- (void) requestConnectionDidFinishLoading:(FBSDKGraphRequestConnection *)connection;If the request connection completes without a network error occurring then this method is called. Invocation of this method does not indicate success of every FBSDKGraphRequest made, only that the request connection has no further activity. Use the error argument passed to the FBSDKGraphRequestHandler block to determine success or failure of each FBSDKGraphRequest. This method is invoked after the completion handler for each FBSDKGraphRequest.
requestConnectionWillBeginLoading:Tells the delegate the request connection will begin loading
| 매개변수 | 설명 |
|---|---|
connection | The request connection that is starting a network request |
- (void) requestConnectionWillBeginLoading:(FBSDKGraphRequestConnection *)connection;If the FBSDKGraphRequestConnection is created using one of the convenience factory methods prefixed with start, the object returned from the convenience method has already begun loading and this method will not be called when the delegate is set.
