向UITextView添加左边距 [英] Adding left margin to UITextView

问题描述

我正在尝试向UITextView添加左边距。

I'm trying to add a left margin to a UITextView.

我尝试过设置属性contentInset，见下文：

I've tried setting the property contentInset, see below:

UITextView *textView = [[UITextView alloc] initWithFrame: CGRectMake(0, 0, self.view.bounds.size.width, self.view.bounds.size.height)];
textView.editable = YES;
textView.autoresizingMask = UIViewAutoresizingFlexibleHeight;
textView.backgroundColor = [UIColor clearColor];
textView.opaque = NO;
textView.contentInset = UIEdgeInsetsMake(0, 15.0f, 0, 0);

这似乎有效，虽然它会导致TextView上我不想要的水平滚动。

This seems to work though it causes horizontal scrolling on the TextView which I don't want.

我只想让左侧的文本插入而不使textview更宽。

I just want the text inset on the left without making the textview any wider.

推荐答案

如果您只想移动文本，请尝试

If you only want to move the text, try

[textView setContentInset:UIEdgeInsetsMake(<#CGFloat top#>, <#CGFloat left#>, <#CGFloat bottom#>, <#CGFloat right#>)];

如果正数将文本框架移向中间，则负数将其移出中间。

Where a positive number moves the "text frame" towards the middle, a negative moves it out from the middle.

例如， [textView setContentInset：UIEdgeInsetsMake（0,20,0，-20）] ，将文本向右移动20个像素！

For example, [textView setContentInset:UIEdgeInsetsMake(0, 20, 0,-20)], will move the text 20 pixels to the right!
