将图像添加到 UITextView [英] Adding Images to UITextView

问题描述

在我的应用程序中，我有一个 UITextView 和一个按钮，用于在编辑时将照片插入到 UITextView 中.

In my app I have a UITextView and a button just below the text view to insert a photo into the UITextView while editing.

我的要求是用户用户能够编辑其中的文本，并在需要时插入图像.

My requirement is that the user user is able to edit the text within, and insert images when needed.

类似于 StackOverflow 的应用程序自己的 UITextView:

推荐答案

您可以将图像视图添加为 UITextView 的子视图.

You can add the image view as a subView of UITextView.

用图像创建一个图像视图:

Create an imageView with image:

UIImageView *imageView = [[UIImageView alloc] initWithImage:yourImage];
[imageView setFrame:yourFrame];
[yourTextView addSubview:imageView];

为了避免重叠使用(感谢@chris):

For avoiding the overlapping use (Thanks @chris):

CGRect aRect = CGRectMake(156, 8, 16, 16);
[imageView setFrame:aRect];
UIBezierPath *exclusionPath = [UIBezierPath bezierPathWithRect:CGRectMake(CGRectGetMinX(imageView.frame), CGRectGetMinY(imageView.frame), CGRectGetWidth(yourTextView.frame), CGRectGetHeight(imageView.frame))];
yourTextView.textContainer.exclusionPaths = @[exclusionPath];
[yourTextView addSubview:imageView];
