So I want to bring in a modal view controller that has a UITextView in it and I want the keyboard to automatically popup and the UITextView have focus.
I found a way to accomplish this by doing the following:
textView.editable = YES;
textView.editable = NO;
This just seems hacky to me, is there another way?
Since UITextView inherits from UIResponder (indirectly, it actually inherits from UIScrollView, which inherits from UIView which then inherits from UIResponder) you can call the -becomeFirstResponder method on your text field, which will cause it to become the first responder and begin editing:
[textView becomeFirstResponder];
That does seem somewhat hackish.
The Cocoa Touch terminology for 'having focus' is 'first responder' and UITextViews will display their keyboards when they are the first responder. I can think of several techniques to make the UITextView become the first responder, but the easiest is probably in your view controller's viewWillAppear or viewDidAppear methods:
- (void)viewWillAppear:(BOOL)animated
{
[myTextView becomeFirstResponder];
[super viewWillAppear:animated];
}
When you want the focus to be that particular TextView on loading a ViewController, you can place the textView.becomeFirstResponder() in the ViewDidLoad overrode func as below:
override func viewDidLoad() {
super.viewDidLoad()
textView.becomeFirstResponder()
}
I find this works without any errors
On Xamarin Forms Custom Render:
protected override void OnElementChanged(ElementChangedEventArgs<Entry> e)
{
base.OnElementChanged(e);
if (Control != null)
{
Control.BecomeFirstResponder();
}
}
