2,828 PointsCan someone help me with task1 of creating a NSArray for the Blog Reader App, Thank you?
I have tried different ways of initializing a new NSArray but it didn't help.
@property (strong, nonatomic) NSArray *booksArray;
self.booksArray.text = [[NSArray alloc] initWithObjects:@"1",nil]; or self.booksArray.text = [[NSArray alloc] arrayWithObjects:@"1",nil];
I'm still lossed. -__-

to create an array you simply declare an object of type NSArray, name it, and allocate and initialize it with values using the initWithObjects method.
NSArray *someArray = [[NSArray alloc] initWithObjects:@"some string", @"someOtherString", nil];
you could also create an array using an array literal:
NSArray *someArray = @[@"some string", @"some other string"];
the challenge tells you what string to put in your array so use the above code as an example. instead of naming it someArray name it booksArray
NSArray *booksArray = [[NSArray alloc] initWithObjects:@"Hamlet", @"King Lear", @"Othello", @"Macbeth", nil];
using literal syntax looks like this:
NSArray *booksArray = @[@"Hamlet", @"King Lear", @"Othello", @"Macbeth"];
I prefer using literal syntax since its much shorter and is very clean.
