iPhone, show NSMutable Array containing NSStrings in UIPickerView

Question

I have a method with the following code:

NSMutableArray *pickerArray = [[NSMutableArray alloc] init];

    int i;

    for(i = 1; i <= 7; i++) {
     NSString *myString = [NSString stringWithFormat:@"%@", i];
     [pickerArray addObject:myString];
    }

    for(i = 1; i <= 7; i++) {
     NSString *fieldName = [[NSString alloc] initWithFormat:@"column%d", i];

     [self setValue:pickerArray forKey:fieldName]; // setValue or initWithArray ???

     [fieldName release];
     [pickerArray release];
    }

    srandom(time(NULL));

When I build the application everything builds correctly but it crashes on start in the console i get the following error:

* -[NSCFString superview]: unrecognized selector sent to instance 0x380da90 * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NSCFString superview]: unrecognized selector sent to instance 0x380da90'

If instead of using an array containing strings I use UIImageView containing UIImages then everything works correctly...

I only would like to populate my picker with an array of numbers from 1 to 50...

Any help would be really appreciated... this thing is driving me mad :)

Answer 1

I don't think you want [myString release]; in your first for loop as the string you create is auto-released (rule of thumb, anything that is created without alloc, init, or new is auto-released)

Answer 2

Problem solved.... was something to do with the number of element in the pickerview, nothing to do with the method itself! Thanks anyway!
