多行可自动调整大小的 UITextView [英] Multiple lines automatically-resizeable UITextView

问题描述

我想在我的 UITextView 中插入几个字符串，以便它们垂直显示

I want to insert a couple of strings to my UITextView so they are displayed vertically

试过这个代码:

NSMutableString* examinationsString = [NSMutableString string];

for (NSString * examination in examinationsArray)
{
    [examinationsString appendString:[NSString stringWithFormat:@"%@, %s ",examination, "\n"]];
}

return examinationsString;

我已将 UITextView Lines 属性更改为 5，但仍将所有内容放在一行中，并以/"分隔

I had changed UITextView Lines property to 5 but still getting all in one line, separated with "/"

我做错了什么?

如果超过 1 行，我还希望 UITextView 拉伸，当然如果它不是自动实现的

I'd also want the UITextView to stretch if there are more than 1 line, if it's not achieved automatically of course

推荐答案

请尝试以下代码:

NSMutableString* examinationsString = [NSMutableString string];

for (NSString * examination in examinationsArray)
{
    [examinationsString appendString:[NSString stringWithFormat:@"%@,\n",examination]];
}
return examinationsString;

现在根据视图的 contentSize 调整 UITextView 的大小:

Now to resize the UITextView as per the view's contentSize:

CGRect frame = _textView.frame;
frame.size.height = _textView.contentSize.height;
_textView.frame = frame;
