How to add a UILabel inside a UIScrollView programatically? - ios

Question

Ok i have already gone through similar questions, but none of them helped.
I want to add a UILabel inside a UIScrollView so that the Label can be scrolled if the contents are large. Here is my code:
ViewController.h:
#interface ViewController : UIViewController
{
UILabel *myLabel;
UIScrollView *myScroll;
}
ViewController.h:
myLabel = [[UILabel alloc]initWithFrame:CGRectMake(self.view.frame.origin.x, self.view.frame.origin.y+30, self.view.frame.size.width, self.view.frame.size.height)];
myScroll = [[UIScrollView alloc] initWithFrame:CGRectMake(self.view.frame.origin.x, self.view.frame.origin.y+30, self.view.frame.size.width, self.view.frame.size.height)];
myLabel.backgroundColor = [UIColor yellowColor];
myLabel.text = #"Large random text";
[myLabel setNumberOfLines:0];
myLabel.lineBreakMode = NSLineBreakByWordWrapping;
[myLabel sizeToFit];
myScroll.contentSize = CGSizeMake(myLabel.frame.size.width,
myLabel.frame.size.height);
[myScroll addSubview:myLabel];
[self.view addSubview:myScroll];
I searched a lot on the internet but could not find a answer, can someone let me know what the issue is ?
Thank You !

Answer 1

I'm not sure how to do that, but I would like to suggest an alternative that may suit your needs. Use a UITextView, but set " [textView userInteractionEnabled:NO] " and it will act as a label, since it cannot be edited. It might end up looking like how you want.

Answer 2

Based on your comments, you need to size the label as needed so it is big enough for the given text. Then add the label to scroll view. Then set the scroll view's contentSize so it fits the whole label. This will ensure the scroll view allows you to scroll to see the whole label.
In addition to this, make sure the label's frame is relative to the scroll view and not to self.view. In other words, setting the label's frame's origin to 0,0 will put the label in the top left corner of the scroll view regardless of the position of the scroll view relative to its parent.

Answer 3

Try by replacing your contentSize like below code,
myScroll.contentSize = CGSizeMake(self.view.frame.size.width,self.view.frame.size.height + 100);
Hope it will work for u.

1.You have to use View(ContentView) to place the labels.
2.Add the ContentView into ScrollVIew.
3.Assign the ContentView Size whatever You Want
