Creating a Data Collection - Implementing an Array incompatible pointer types assigning to NSString from NSArray

Hey Guys, I am having an issue assigning my NSArray to my prediction Label. Xcode is saying "incompatible pointer types assigning to NSString from NSArray". Can somebody please take a look at my code an tell me what I am doing wrong.

  • (IBAction)buttonPressed { NSArray *predictions = [[NSArray alloc] initWithObjects:@"It is Certain",@"Decidedly so", @"The stars are not aligned",@"My reply is no",@"It is doublful",@"Better not tell you now",@"Concertrate and ask again",@"Unable to answer now", nil ];

    self.predictionLabel.text = [predictions objectsAtIndexes:0];


1 Answer

Because objectsAtIndexes returns an array:

- (NSArray *)objectsAtIndexes:(NSIndexSet *)indexes

Are you trying to just get the value at position 0? Then try objectAtIndex;

   [predictions objectAtIndex:0];

Also sometimes you may need to cast it, so that it knows that the object at that position is of a certain type.

self.predictionLabel.text =(NSString*)[predictions objectAtIndex:0];

Thanks So Much Kerde. I can see the mistake I made now.

No problem!
