sectioned table view returning blank table - ios

Question

I found code examples online for creating a tableview with alphabetical sections and i have tried to adapt for my tableview.
However, now the simulator is returning a blank table.
I've obviously gone wrong, anyone mind pointing out the mistakes?
Every change I make doesn't help.
Thank you

There are a bunch of things that are not optimal with your code but what is causing the table to be blank is most likely that you are never populating sectionData and sectionName and so it returns a table with no section names or section data. Try this:
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
NSArray *words = [NSArray arrayWithObjects:#"Tee", #"Club", #"Green", #"Putt", nil];
NSArray *sortedWords = [words sortedArrayUsingSelector:#selector(caseInsensitiveCompare:)];
NSString *currentLetter = #"";
for (NSString *string in sortedWords) {
if (string.length>0) {
NSString *letter = [string substringToIndex:1];
if (![letter isEqualToString:currentLetter]) {
[sectionNames addObject:letter];
currentLetter = letter;
NSMutableArray *oneSection = [NSMutableArray array];
[sectionData addObject:oneSection];
[[sectionData lastObject]addObject:string];
}
}
}
}
