Core Data to populate UITableView: can't get a NSString - objective-c

Question

my app stores players's data and I want to populate a UITableView with it, but I'm afraid I'm a bit lost.
Here's my code:
ShowResults.h
#import <UIKit/UIKit.h>
#interface ShowResults : UITableViewController<UITableViewDelegate,UITableViewDataSource, NSFetchedResultsControllerDelegate>
{
NSManagedObjectContext *managedObjectContext;
NSFetchedResultsController *fetchedResulstController;
NSArray *fetchedObjects;
}
#property (nonatomic) NSFetchedResultsController *fetchedResultsController;
#property (nonatomic) NSManagedObjectContext *managedObjectContext;
#property (nonatomic,strong) NSArray *fetchedObjects;
#end
ShowResults.m
#import "ShowResults.h"
#import "F1AppDelegate.h"
#interface ShowResults ()
#end
#implementation ShowResults
#synthesize managedObjectContext;
#synthesize fetchedResultsController;
#synthesize fetchedObjects;
- (id)initWithStyle:(UITableViewStyle)style
{
self = [super initWithStyle:style];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
F1AppDelegate *appDelegate =[[UIApplication sharedApplication]delegate];
NSManagedObjectContext *context =[appDelegate managedObjectContext];
NSError *error;
if (managedObjectContext != nil) {
if ([managedObjectContext hasChanges] &&[managedObjectContext save:&error]) {
NSLog(#"Unresolved error %#,%#",error, [error userInfo]);
abort();
}
}
NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init];
NSEntityDescription *entity = [NSEntityDescription
entityForName:#"Players" inManagedObjectContext:context];
[fetchRequest setEntity:entity];
fetchedObjects = [context executeFetchRequest:fetchRequest error:&error];
// Test reading core data
for (NSManagedObject *player in fetchedObjects) {
NSLog(#"Name: %#", [player valueForKey:#"name"]);
NSLog(#"Surname: %#", [player valueForKey:#"surname"]);
NSLog(#"Address: %#", [player valueForKey:#"address"]);
NSLog(#"Email: %#", [player valueForKey:#"email"]);
NSLog(#"Phone: %#", [player valueForKey:#"phone"]);
NSLog(#"City: %#", [player valueForKey:#"city"]);
NSLog(#"Country: %#", [player valueForKey:#"country"]);
NSLog(#"Store: %#", [player valueForKey:#"store"]);
NSLog(#"Age: %#", [player valueForKey:#"age"]);
NSLog(#"Gender: %#", [player valueForKey:#"gender"]);
NSLog(#"Time: %#", [player valueForKey:#"time"]);
}
// End test
}
- (void)viewDidUnload
{
[super viewDidUnload];
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return YES;
}
#pragma mark - Table view data source
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
// Return the number of sections.
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
// Return the number of rows in the section.
NSInteger rows = [fetchedObjects count];
return rows;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *MyIdentifier = #"MyIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:MyIdentifier];
}
NSString *pieceOfData =[NSString stringWithFormat:#"%#", [fetchedObjects objectAtIndex:indexPath.row]];
cell.textLabel.font = [UIFont fontWithName:#"Helvetica" size:14];
cell.textLabel.text = pieceOfData;
NSLog(#"cellContent: %#",pieceOfData);
return cell;
}
#end
What I get on console output is
Name: Otto
Surname: Von Bismarck
Address: Schuhe, 3
Email: otto#munchen.de
Phone: [phone]
City: MÜNCHEN
Country: GERMANY
Store: MÜNCHEN
Age: 44
Gender: Male
Time: 03:01:00
cellContent: <Players: 0x6b8f3c0> (entity: Players; id: 0x6b8b450 <x-coredata://C61C85CA-EB53-4B88-87AF-CC45EABFF8ED/Players/p1> ; data: {
address = "Schuhe, 3";
age = 44;
city = "M\U00dcNCHEN";
country = GERMANY;
email = "otto#munchen.de";
gender = Male;
name = Otto;
phone = "[phone]";
store = "M\U00dcNCHEN";
surname = "Von Bismarck";
time = "03:01:00";
})
Can you help me to write these values into the tableView cells?
Thanks !

Answer 1

It looks like you are just need to do something like this:
// in your cellForRowAtIndexPath:
Players *player = [fetchedObjects objectAtIndex:indexPath.row];
// switch email for whatever other property you want to display
cell.textLabel.text = player.email;
It also looks like you might need to import Players.h into your class.
