IOS - remove ALL padding from UITextView

问题

There are many great examples on SO to remove the left padding of a UITextView.

How to lose margin/padding in UITextView?

However, I need to remove the right padding too.

I have tried...

[tv setContentInset: UIEdgeInsetsMake(-4,-8,-8,-X)];//where X is any integer

and just about every other permutation of the last two values to remove the padding and nothing seems to work. Have also tried

[tv sizeToFit];
[tv setTextAlignment:[NSTextAlignmentRight]];

The following Text in the Textview says "00"

回答1:

Although it is iOS 7 only, an extremely clean solution is to set the textView's textContainerInsets as such:

[textView setTextContainerInset:UIEdgeInsetsZero];
textView.textContainer.lineFragmentPadding = 0; // to remove left padding

This will effectively remove all padding (insets) around the text inside the text view. If your deployment target is iOS 7+ then this is the best solution thus far.

回答2:

To completely remove all padding, the lineFragmentPadding must be taken into account.

let padding = textView.textContainer.lineFragmentPadding
textView.textContainerInset = UIEdgeInsetsMake(0, -padding, 0, -padding)

The lineFragmentPadding default value is 5, and is at the beginning and end of fragment rectangle.

Some answers suggested setting lineFragmentPadding to 0. However, as per discussed in the doc, it is not designed to express text margins. So do not set it to 0.

Please try sub-classing the UITextView and overriding the following method:

    - (id)styleString
{
    return [[super styleString] stringByAppendingString:@"; line-height: 1.6em;margin-right: 30px; margin-left: 0px; margin-top: 0px;"];
}

Apparently; you can tweak the margin-left, margin-top & whatever you want ;)

My problem is solved this way

if([Utils isiOS7orHigher]){
    commentView.textContainerInset = UIEdgeInsetsZero;
}else {
    commentView.contentInset = UIEdgeInsetsMake(-11,-8,0,0);
}
