Question

I have custom object and I have stored my values in Array. but I am bit stuck to show objects values form array. My code definition is here.

for (int i = 0; i < 20; i++)
 {
Person *myPerson = [[Person alloc] init];
myPerson.name = @"Brian";
myPerson.age = [NSNumber numberWithInteger:23];     
[myArray addObject:myPerson];       
[myPerson release];         
}

Now I want to show all 20 values which is stored in Array (name and age of person).
How will I show that values?

Answer 1

There are many different ways of showing the customers depending on what you want.

1. Print to the console

If you just want to print them out to the console, you can use:

for (int i = 0; i < 20; i++)
{
    Person *thisPerson = [myArray objectAtIndex:i];
    NSLog(@"%@ has an age of %d", thisPerson.name, thisPerson.age);
}

additionally, you can use Fast Enumerators to neaten things up:

for (Person *thisPerson in myArray) 
{
    NSLog(@"%@ has an age of %d", thisPerson.name, thisPerson.age);
}

2. Showing in a table view

You’ll need a UITableView with an instance of UITableViewController that conforms to the UITableViewDataSource protocol.
