多行可自动调整大小的 UITextView [英] Multiple lines automatically-resizeable UITextView
本文介绍了多行可自动调整大小的 UITextView的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
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;
