Insert NSArray of strings into UILabel and count by 1. - ios

Question

How Would I insert an array of strings into UILabel, and have them load or count by 1?
I'm trying to load the following array into the UILabel:
self.array = [NSArray arrayWithObjects:#"Testing 1",#"Testing 2",#"Testing 3", nil];
Here I am using an UIScrollView that automatically changes from each slide to each slide:
for (int i=1; i<=3; i++) {
// create label
UILabel *text = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width,30)];
text.text = [NSString stringWithFormat:#"%#", self.array];
text.font=[UIFont fontWithName:#"HelveticaNeueLTStd-LtCn" size:15];
text.textColor = [UIColor darkGrayColor];
text.textAlignment =NSTextAlignmentCenter;
// create imageView
UIImageView *lblView = [[UIImageView alloc] initWithFrame:CGRectMake((i-1)*scrMain.frame.size.width, 325, 280, 240)];
// set label
[lblView addSubview:text];
// apply tag to access in future
lblView.tag=i+1;
// add to scrollView
[scrMain addSubview:lblView];
}
I have an example of how to do it with UIImageView:
for (int i=1; i<=3; i++) {
// create image
UIImage *image = [UIImage imageNamed:[NSString stringWithFormat:#"sti%02i.png",i]];
// create imageView
UIImageView *imgV = [[UIImageView alloc] initWithFrame:CGRectMake((i-1)*scrMain.frame.size.width + 23, 60, 280, 260)];
// set scale to fill
imgV.contentMode=UIViewContentModeScaleToFill;
// set image
[imgV setImage:image];
// apply tag to access in future
imgV.tag=i+1;
// add to scrollView
[scrMain addSubview:imgV];
}
The images are in my project and are numbered sti01, sti02, and so on... It then counts by one for each images and then loads them into the scrollview. I hope this helps!

The y-position of the label should be adjusted according to the index.
You can use the array count instead of a fixed '3'.
You don't need an UIImageView in between.
You can try this:
for (int i = 0; i < self.array.count; i++) {
// create label
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, i*30, self.view.frame.size.width,30)];
label.text = [self.array objectAtIndex:i];
label.font = [UIFont fontWithName:#"HelveticaNeueLTStd-LtCn" size:15];
label.textColor = [UIColor darkGrayColor];
label.textAlignment = NSTextAlignmentCenter;
// add to scrollView
[scrMain addSubview:label];
}

If I'm understanding you correctly, you need to make the following change:
text.text = [NSString stringWithFormat:#"%#", [self.array objectAtIndex:i]];
This will pull out the ith object from your array of strings and set that as the text of your UILabel.

Why don't you loop through the array instead of trying to assign the text to the whole array like this:
for (int i=0; i<3; i++) {
// create label
UILabel *text = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width,30)];
text.text = [NSString stringWithFormat:#"%#", [self.array objectAtIndex:i]];
text.font=[UIFont fontWithName:#"HelveticaNeueLTStd-LtCn" size:15];
text.textColor = [UIColor darkGrayColor];
text.textAlignment =NSTextAlignmentCenter;
// create imageView
UIImageView *lblView = [[UIImageView alloc] initWithFrame:CGRectMake((i-1)*scrMain.frame.size.width, 325, 280, 240)];
// set label
[lblView addSubview:text];
// apply tag to access in future
lblView.tag=i+1;
// add to scrollView
[scrMain addSubview:lblView];
}
That way you're just pulling that one string out, assigning it as the UILabel's text, then adding it as a subview to the appropriate imageView.
