iOS UITextView 純英文排版換行出錯(cuò)的解決方案
博客中代碼：
NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc]init];
paragraphStyle.lineBreakMode = NSLineBreakByCharWrapping;
NSDictionary *attributes = @{NSParagraphStyleAttributeName:paragraphStyle};
_contentTextView.attributedText = [[NSAttributedString alloc]initWithString:_contentTextView.text attributes:attributes];
對應(yīng)的[Swift](http://lib.csdn.net/base/swift)代碼：
let paragraphStyle = NSMutableParagraphStyle()
paragraphStyle.lineBreakMode = NSLineBreakMode.ByCharWrapping;
let attributes = [NSParagraphStyleAttributeName:para]
_contentTextView.attributedText = NSAttributedString.init(string:_contentTextView.text, attributes: attributes)
