Pending Operation

You can manage the pending state.

(void)submitPending – Submits the operation so that it can be replayed on the Unwired Server. A request is sent to the Unwired Server during a synchronization.
```
[customer submitPending];
```
(void)cancelPending – Cancels a pending record. A pending record is one that has been updated in the local client database, but not yet sent to the Unwired Server.
```
[customer cancelPending];
```
+(void)submitPendingOperations – Submits all data for all pending records to the Unwired Server. This method internally invokes the submitPending method.
```
[Customer submitPendingOperations];
```
+(void)submitPendingOperations:(NSString*)synchronizationGroup – Submits all data for pending records from MBOs in this synchronization group to the Unwired Server. This method internally invokes the submitPending method.
```
[SampleAppSUP101DB submitPendingOperations:@”default”];
```
(void)cancelPendingOperations – Cancels the pending operations for an entire entity. This method internally invokes the cancelPending method.
```
[Customer cancelPendingOperations];
```
Note: Use the submitPendingOperations and cancelPendingOperations methods only when there are multiple pending entities on the same MBO type. Otherwise, use the MBO instance’s submitPending or cancelPending methods, which are more efficient if the MBO instance is already available in memory.

SampleAppCustomer *customer = [SUP101Customer find:101]; 
//Make some changes to the customer record.
//Save the changes

//If the user  wishes to cancel the changes, a call to cancel pending will revert to the old values.

[customer cancelPending]; 

// The user can submit the changes to the server as follows:
[customer submitPending];
