UITextView background image

Question

How can I set up a background image to UITextView?

Answer 1

I found one simple method how to set background image.

h file

@interface FNTextView : UITextView

@end

m file

...
- (void)drawRect:(CGRect)rect
{
    [self.bgImage drawInRect:rect];

    [super drawRect:rect];
}

- (void)initHandler
{
    self.bgImage = [[UIImage imageNamed:@"textview_bg"] resizableImageWithCapInsets:UIEdgeInsetsMake(4, 4, 4, 4)];
}
...

Answer 2

UITextView *textView=[[UITextView alloc]initWithFrame: CGRectMake(20, 20, 40, 40)];
textView.text = @"this is a test \n this is test \n this is a test";
UIImageView *img = [[UIImageView alloc]initWithFrame: textView.frame];
img.image = [UIImage imageNamed: @"image.png"];
[self.view addSubview:textView];
[self.view insertSubview:img belowSubview:textView];

Answer 3

Not sure about, but you can try the following, assuming that your background image is handled by a UIImageView:

[myTextView addSubview: myImageView];

Note that you may need to change the value of the alpha/opaque properties of your UITextView.

Kind Regards.

Answer 4

The answers of @dulcanwilcox and @oxigen both work, but, an addition would be to make the background image resizable, in case the image is being used to show some kind of border.

UITextView *textView = [[UITextView alloc]initWithFrame: window.frame];
textView.text = @"Some text...";

UIImageView *imgView = [[UIImageView alloc]initWithFrame: textView.frame];
imgView.image = [[UIImage imageNamed: @"image"] resizableImageWithCapInsets:UIEdgeInsetsMake(8, 8, 8, 8)];

[textView addSubview:imgView];
[textView sendSubviewToBack:imgView];

[window addSubview:textView];

Check out the documentation for resizableImageWithCapInsets:(UIEdgeInsets)capInsets.
