Creating a custom class

here is the task- 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.

my code is-

import "Quote.h"

@implementation Quote

  • (NSString *) quotes {

if(_quotes == nil){

_quotes=[[NSArray alloc] initWithObjects: @"Hey There", @"Hows you?", @"Hope you r gud!", nil]; }

return _quotes;

}

@end please help me in understanding where m wrong!

the problem is your return type

- (NSString *) quotes {

this is a getter for your quotes variable. However quotes is an NSArray, not an NSString.

try changing your return type to NSArray.

- (NSArray *) quotes {
    if (_quotes == nil) {

         _quotes = [[NSArray alloc] initWithObjects:@"Hey There", @"Hows you?", @"Hope you r gud!", nil];

    }

    return _quotes;
}
