IOS - 从UITextView中删除所有填充 [英] IOS - remove ALL padding from UITextView

问题描述

有很多很好的例子可以删除UITextView的左侧填充。

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

How to lose margin/padding in UITextView?

但是，我需要删除正确的填充。

However, I need to remove the right padding too.

我试过......

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

以及最后两个值的每个其他排列，以删除填充，似乎没有任何效果。还尝试了

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]];

Textview中的以下文字说00

The following Text in the Textview says "00"

推荐答案

虽然它只是iOS 7，但是一个非常干净的解决方案是将textView的textContainerInsets设置为：

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

这将有效删除文本内部文本周围的所有填充（插入）视图。如果您的部署目标是iOS 7+，那么这是迄今为止最好的解决方案。

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.
