I\'ll get right to it. I have a UItextView
placed in my view that when needs to scroll to see all the text (when a lot of text is present in the textView) the t
Swift 4.2 & Swift 5
set content offset both before and after setting the text. (on the main Thread)
let animation = false //or whatever you want
self.mainTextView.setContentOffset(.zero, animated: animation)
self.mainTextView.attributedText = YOUR_ATTRIBUTED_TEXT
self.mainTextView.setContentOffset(.zero, animated: animation)
In my case I was loading a textView in a Custom tableview cell. Below is what I did to make sure the text in a textview loads at the top of the text in my textview in my custom cell.
1.) In storyboard, set the textview ScrollEnabled = false by unchecking the button.
2.) You set the isScrollEnabled to true on the textview after the view loads. I set mine in a small delay like below:
override func awakeFromNib() {
super.awakeFromNib()
let when = DispatchTime.now() + 1
DispatchQueue.main.asyncAfter(deadline: when){
self.textView.isScrollEnabled = true
}
}
Regardless, if you are in my situation or not, try setting scrollEnabled to false and then when the view loads, set scrollEnabled to true.
Put this one line of code in ViewDidLoad
self.automaticallyAdjustsScrollViewInsets = false
I translated zeeple's answer to MonoTouch/Xamarin (C#).
public override void ViewDidLayoutSubviews()
{
base.ViewDidLayoutSubviews();
myForm.SetContentOffset(new CoreGraphics.CGPoint(0,0), animated: false);
}
Create an outlet for your UITextView
in the ViewController.swift
file. In the ViewDidLoad
section put the following:
Swift:
self.textView.contentOffset.y = 0
I have tried:
self.textView.scrollRangeToVisible(NSMakeRange(0, 0))
For Swift >2.2, I had issues with iOS 8 and iOS 9 using above methods as there are no single answer that works so here is what I did to make it work for both.
override func viewWillAppear(animated: Bool) {
super.viewWillAppear(animated)
if #available(iOS 9.0, *) {
textView.scrollEnabled = false
}
self.textView.scrollRangeToVisible(NSMakeRange(0, 0))
}
override func viewDidAppear(animated: Bool) {
super.viewDidAppear(animated)
if #available(iOS 9.0, *) {
textView.scrollEnabled = true
}
}
