Ios – Change textColor of a UITextView in Swift

iosswift2textcoloruitextview

I have an iOS project I'm working on using Xcode7 and Swift2. I have a UITextView that I'm trying to change the textColor of. It has a black background color.

I looked here and could not find a setTextColor. I also tried below in the UIViewController of where the UITextView is located with no luck:

@IBOutlet weak var codeText: UITextView!
override func viewDidLoad() {
    super.viewDidLoad()

    self.codeText.delegate = self

    codeText.textColor = UIColor.whiteColor()
}

I then went into the Inspector and tried clicking on the UITextView and changing the textColor there with no luck of it changing. Am I doing something wrong?

Thank you.

on your ViewController remove the line

self.codeText.delegate = self

You can not assign a value of type "ViewController" to type "UITextViewDelegate?"

codeText.textColor = UIColor.redColor()

works just fine.

Ios – How to size a UITextView to its content

This works for both iOS 6.1 and iOS 7:

- (void)textViewDidChange:(UITextView *)textView
{
    CGFloat fixedWidth = textView.frame.size.width;
    CGSize newSize = [textView sizeThatFits:CGSizeMake(fixedWidth, MAXFLOAT)];
    CGRect newFrame = textView.frame;
    newFrame.size = CGSizeMake(fmaxf(newSize.width, fixedWidth), newSize.height);
    textView.frame = newFrame;
}

Or in Swift (Works with Swift 4.1 in iOS 11)

let fixedWidth = textView.frame.size.width
let newSize = textView.sizeThatFits(CGSize(width: fixedWidth, height: CGFloat.greatestFiniteMagnitude))
textView.frame.size = CGSize(width: max(newSize.width, fixedWidth), height: newSize.height)

If you want support for iOS 6.1 then you should also:

textview.scrollEnabled = NO;

Ios – How to lose margin/padding in UITextView

For iOS 7.0, I've found that the contentInset trick no longer works. This is the code I used to get rid of the margin/padding in iOS 7.

This brings the left edge of the text to the left edge of the container:

textView.textContainer.lineFragmentPadding = 0

This causes the top of the text to align with the top of the container:

textView.textContainerInset = .zero

Both lines are needed to completely remove the margin/padding.
