Question

Very basic question 🙂

I have to initialize an array in objective-c. I will further use that array value in table view. I have a listing of chapters and I have written it as hardcoded like below.

    NSArray *tableList;

tableList = [[NSArray alloc]initWithObjects:@"Chapter 1",@"Chapter 2",@"Chapter 3",@"Chapter 4",@"Chapter 5",nil];

But now I have a indexed array which is keeping chapters details. below is the code of array which is holding value.

 extern NSArray *wallvalue;

    for (NSDictionary *chapter in wallvalue) {
        NSString *chapterName = [person objectForKey:@"chapters"];
        if([chapterName length] >0)
        {

            NSLog(chapterName);
        }
    }

Now I want to show these chapterName in my tablelist. How will I do this ?

Thanks in advance.

Answer 1

NSMutableArray *tableList = [[NSMutableArray alloc] initWithCapacity:[wallvalue count]];
for (NSDictionary *chapter in wallvalue) {
    NSString *chapterName = [person objectForKey:@"chapters"];
    if([chapterName length] >0)
    {
        [tableList addObject:chapterName];
    }
}
