Bordered UITextView

Question

I want to have a thin gray border around a UITextView. I have gone through the Apple documentation but couldn\'t find any property there. Please help.

Answer 1

I add UIImageView as a subview of the UITextView. This matches the native border on a UITextField, including the gradient from top to bottom:

textView.backgroundColor = [UIColor clearColor];
UIImageView *borderView = [[UIImageView alloc] initWithFrame: CGRectMake(0, 0, textView.frame.size.width, textView.frame.size.height)];
borderView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;
UIImage *textFieldImage = [[UIImage imageNamed:@"TextField.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(15, 8, 15, 8)];
borderView.image = textFieldImage;
[textField addSubview: borderView];
[textField sendSubviewToBack: borderView];

These are the png images I use, and a jpg representation:

@1x

@2x

Answer 2

this is as close as I could from an original UITextField

func updateBodyTextViewUI() {
    let borderColor = UIColor.init(red: 212/255, green: 212/255, blue: 212/255, alpha: 0.5)

    self.bodyTextView.layer.borderColor = borderColor.CGColor
    self.bodyTextView.layer.borderWidth = 0.8
    self.bodyTextView.layer.cornerRadius = 5
}

Answer 3

for Swift Programming, use this

tv_comment.layer.borderWidth = 2
tv_comment.layer.borderColor = UIColor(red: 0.2, green: 0.2, blue: 0.2, alpha: 1).CGColor

Answer 4

The thing that made it work (in addition to following the answers here) is adding the borderStyle attribute:

#import <QuartzCore/QuartzCore.h>
..

phoneTextField.layer.borderWidth = 1.0f;
phoneTextField.layer.borderColor = [[UIColor blueColor] CGColor];
phoneTextField.borderStyle = UITextBorderStyleNone;

Answer 5

Add the following for rounded corners:

self.yourUITextview.layer.cornerRadius = 8; 

Answer 6

In Swift 3, you may use the following two lines:

myText.layer.borderColor = UIColor.lightGray.cgColor

myText.layer.borderWidth = 1.0
