MR_saveToPersistentStoreAndWait not saving data from array

I've an

in which I'm adding objects after user selects multiple rows from a tableview. After selecting user press confirm and it saves the data. So based on some example I found here I have implemented the code but it seems as it is only saving one value at a time. The last value that user selects:

- (IBAction)confirmPressed:(id)sender {
NSLog(@"Selected Are: %@ - %@",selectedDX,selectedDesc);
for (NSString *code in selectedDX) {
if (!_dxToAddEdit) {
self.dxToAddEdit = [Diagnoses MR_createEntity];

[self.dxToAddEdit setCode:code];
[self.dxToAddEdit setCodeDescription:@"Sample Description"];
[self.dxToAddEdit setSuperBill:_forSuperBill];

[[NSManagedObjectContext MR_defaultContext] MR_saveToPersistentStoreAndWait];
[self.navigationController popViewControllerAnimated:YES];



You are working only with one managed object self.dxToAddEdit. And it will contain the last code from array. If you want to save multiple objects you should do the following:

NSManagedObjectContext *defaultContext = [NSManagedObjectContext MR_defaultContext];
for (NSString *code in selectedDX) {
    Diagnoses *newDiagnose = [Diagnoses MR_createEntityInContext:defaultContext];

    newDiagnose.code = code;
    newDiagnose.codeDescription = @"Sample Description";
    newDiagnose.superBill = _forSuperBill;

// Save recently created objects to persistent store.
[defaultContext MR_saveToPersistentStoreAndWait];
