Only Able to Save The First Object - ios

Question

A problem I'm facing right now is that when I try to save objects, Core Data appears to only save the first one.
Code to save objects
- (void)savingResCore {
AppDelegate *delegate = [[UIApplication sharedApplication]delegate];
NSManagedObjectContext *context = [delegate managedObjectContext];
ResultMO *resEntity = [NSEntityDescription insertNewObjectForEntityForName:#"Result" inManagedObjectContext:context];
if(indCheck == 1) {
resEntity.result1 = pena1;
resEntity.resuName1 = penaNam1;
}
if(indCheck == 2) {
resEntity.result2 = pena2;
resEntity.resuName2 = penaNam2;
}
if(indCheck == 3) {
resEntity.result3 = pena3;
resEntity.resuName3 = penaNam3;
}
_seqNameChk = [NSNumber numberWithInt:[_seqNameChk intValue] - 1];
if([_seqNameChk isEqual:#(0)]){
NSError *error = nil;
if (context != nil) {
if ([context hasChanges] && ![context save:&error]) {
NSLog(#"Unresolved error %#, %#", error, [error userInfo]);
abort();
}
}
}
}
Code to fetch objects
- (void)fetchResCore {
AppDelegate *delegate = [[UIApplication sharedApplication]delegate];
NSManagedObjectContext *context = [delegate managedObjectContext];
NSEntityDescription *descriptor = [NSEntityDescription entityForName:#"Result" inManagedObjectContext:context];
NSFetchRequest *request = [[NSFetchRequest alloc]init];
request.entity = descriptor;
NSError *error;
NSArray *contArr = [context executeFetchRequest:request error:&error];
if(contArr == nil){
NSLog(#"Problems fetching data.");
}
else if(contArr != nil) {
if(contArr.count == 0) {
NSLog(#"No objects saved");
}
else {
NSManagedObject *resu = (NSManagedObject *)[contArr objectAtIndex:0];
NSLog(#"1 - %#", resu);
pena1 = [resu valueForKey:#"result1"];
penaNam1 = [resu valueForKey:#"resuName1"];
NSLog(#"%#", pena1);
pena2 = [resu valueForKey:#"result2"];
penaNam2 = [resu valueForKey:#"resuName2"];
NSLog(#"%#", pena2);
pena3 = [resu valueForKey:#"result3"];
penaNam3 = [resu valueForKey:#"resuName3"];
NSLog(#"%#", pena3);
NSLog(#"2 - %#", resu);
}
}
}
For example, I have a button that increments indCheck by one each time it is pressed and each time it calls up the fetchResCore method. Assume seqNameChk = 2. For the first time, the attributes result1 & resuName1 gets saved successfully. After the button is pressed consecutively, it no longer saves data. Hence, attributes result2, resuName2, result3 & resuName3 does not contain data when retrieved at the fetchResCore method.
Result printed in the console for resu
resuName1 = "(\n Alan\n)";
resuName2 = nil;
resuName3 = nil;
result1 = "(\n 100\n)";
result2 = nil;
result3 = nil;
Result printed in the console for contArr
result1 = \"(\\n 100\\n)\";\n result2 = nil;\n result3 = nil;\n
resuName1 = \"(\\n Alan\\n)\";\n resuName2 = nil;\n resuName3 = nil;\n

As Jon Rose had pointed out,
I would assume that they are all in the array contArr but you are only looking at the first one: NSManagedObject *resu = (NSManagedObject *)[contArr objectAtIndex:0];
I printed out contArr.count and it resulted in a 3. I've also printed out the contents of the array by using a for loop and again, 3 elements which were populated, was displayed.
To solve the problem, I had to rectify [contArr objectAtIndex:0] as it only displayed the first element in the array.
In the fetchResCore method
for(int i = 0; i < contArr.count; i++){
NSManagedObject *resu = (NSManagedObject *)[contArr objectAtIndex:i];
NSLog(#"1 - %#", resu);
if(pena1.count == 0 && penaNam1.count == 0){
pena1 = [resu valueForKey:#"result1"];
penaNam1 = [resu valueForKey:#"resuName1"];
NSLog(#"%#", pena1);
}
if(pena2.count == 0 && penaNam2.count == 0){
pena2 = [resu valueForKey:#"result2"];
penaNam2 = [resu valueForKey:#"resuName2"];
NSLog(#"%#", pena2);
}
if(pena3.count == 0 && penaNam3.count == 0){
pena3 = [resu valueForKey:#"result3"];
penaNam3 = [resu valueForKey:#"resuName3"];
NSLog(#"%#", pena3);
}
}
Thanks again, Jon Rose for pointing out a simple mistake that took me days to figure out.
