UITextView背景图片

Question

如何为UITextView设置背景图像？

Answer 1

You can have an UIImageView containing the background image and the UITextView as siblings, then in Interface Builder move the text view to overlap the image view (or add them both to the same parent view if doing it programmatically). You also need to make sure that text view is not opaque and give it a 0% opacity background .

Answer 2

UITextView *textView = [[UITextView alloc]initWithFrame: window.frame];
textView.text = @"text\n text\n text";
UIImageView *imgView = [[UIImageView alloc]initWithFrame: textView.frame];
imgView.image = [UIImage imageNamed: @"myImage.jpg"];
[textView addSubview: imgView];
[textView sendSubviewToBack: imgView];
[window addSubview: textView];

Answer 3

@durai: Your image has a height limit after which white background will appear if empty background appears after it scrolls down then you can repeat the same image.

This might be helpful:

textView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed: @"Image.png"]];

Answer 4

Just one clarification, when trying out answer #9 from @oxigen , I found out that this line:

UIImageView *imgView = [[UIImageView alloc]initWithFrame: textView.frame];

Is relative to the textView.frame . So your x and y values need to be 0,0 if you want it to overlap completely which means you want something like:

UIImageView *imgView = [[UIImageView alloc]initWithFrame:textView.bounds];

Answer 5

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 6

[txtView setBackgroundColor:[UIColor colorWithPatternImage:[UIImage imageNamed:@"image.png"]]];

Answer 7

For tiled background i like this solution

UIImage *patternImage = [UIImage imageNamed:@"image.png"];
UIColor* color = [UIColor colorWithPatternImage:patternImage];
textView.backgroundColor = color;

Answer 8

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 9

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 .

Answer 10

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.
