6,803 Pointscode challenge
hello i am stuck on task 2 of 3 on the code challange on creating a custom class on the build a simple iphone app this is what im asked..
Switch to the implementation file and implement a 'quotes' method which will allocate and initialize the _quotes instance variable only if it is 'nil'. Initialize the array with any three strings.
this is the code i have entered..
@implementation _quotes
- (NSArray *) quotes {
if (_quotes == nil){
quotes = [[NSArray alloc] initWithObjects:@"It is Certain",
@"It is Decidedly so",
@"All signs say YES!", nil];
}
return _quotes;
}

Treehouse Guest TeacherYou are almost right except for one little issue. On the line after the if statement you missing an underscore prefix for the instance variable _quotes.

Treehouse Guest TeacherNoticed that you renamed the @implementation. Change it back what it was.

6,803 Pointsit still doesnt seem to be working, this is what my code looks like now..
@implementation Quote
- (NSArray *) quotes { if (_quotes == nil){ _quotes = [[NSArray alloc] initWithObjects:@"It is Certain", @"It is Decidedly so", @"All signs say YES!", nil]; } return _quotes; }
