Question

If the user provides a number, such as 8, how exactly would I place eight labels onto the view?

For example:

int userGivenNumber = textfield.text;

for (int labelNumber=1; i<=userGivenNumber; i++) {

    UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(50, *previousLabel*.frame.origin.y + 20)];

}

How would you get the location of previousLabel? Additionally, if the user wanted to edit a label, such as label 3, how would I edit this label?

The problem is that I don’t know how many labels they want to place while coding, and I have no way of keeping track of the labels, since they are called label. Do you have any ideas? Do you understand what I am asking? Thanks for your help.

- (void)addLabels {

    CGFloat offset = 0;

    // labels is NSMutableArray property

    labels = [[NSMutableArray alloc] initWithCapacity:8];

    for (int i = 0; i < 8; i++) {
        UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, offset, 320, 20)];
        [self.view addSubview:label];
        [labels addObject:label];

        offset += label.frame.size.height;
    }

}

Edit: Like jerrylroberts said, to access the label array from elsewhere in your code, you should declare it as a property.
