How to word wrap text in a UITextView?
提问by Pangu
I have a UITextView contained within a UIScrollView. The UITextView is loaded dynamically depending on the UISegmentedControl, but I don't know how to word wrap it so the word moves to the next line.
我有一个包含在 UIScrollView 中的 UITextView。UITextView 是根据 UISegmentedControl 动态加载的，但我不知道如何对其进行自动换行，以便单词移动到下一行。
.m:
.m:
@interface Tester ()
{
UITextView *sponsor;
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
sponsorInfo = [ [UITextView alloc] initWithFrame:self.sponsorsScrollView.frame];
[sponsor setEditable:NO];
}
- (IBAction)control:(UISegmentedControl *)sender
{
if (self.sponsorSegmentedControl.selectedSegmentIndex == 0)
{
[self changeGenericAbout:self.cellIndex];
}
else
{
//
}
}
- (void)changeGenericAbout:(int)index
{
if (index == 0)
{
sponsorInfo.text = @"[text in screen shot]";
[sponsor sizeToFit];
[self.sponsorsScrollView addSubview:sponsor];
}
}
How can I achieve this word wrapping in iOS 7+?

First off I think your textview looks a bit strange. Shouldn't there be a margin on the right side as well? Now it sort of looks like the textview continues to the right. Are the frames correct or have you done something to the textContainerInset?
首先，我认为您的 textview 看起来有点奇怪。右侧不应该也有边距吗？现在看起来 textview 继续向右。框架是否正确，或者您是否对 textContainerInset 进行了某些操作？
Anyway to answer your question regarding changing linebreaks: a textview's textContainer property has a lineBreakMode which could be set to NSLineBreakByWordWrapping. I think that should solve it
无论如何回答您关于更改换行符的问题：textview 的 textContainer 属性有一个 lineBreakMode，可以设置为 NSLineBreakByWordWrapping。我认为应该解决它
