 1 | # STTextView
 2 | ##我们知道iOS自带的UITextView基本很难满足我们的日常使用。我项目中textView是继承与UITextview的，自定义了一个TextView，主要实现的以下功能。
 3 | 1. 添加placeHolder
 4 | 2. 高度自适应
 5 | 3. 可以设置行间距
 6 | 4. 支持xib
 7 | 看一下实际使用效果吧：
 8 | ![实际使用效果](http://upload-images.jianshu.io/upload_images/1663049-631fb8cb7158d9ac.gif?imageMogr2/auto-orient/strip)
 9 | 希望能够帮助到大家吧，下载拖进工程即可使用，如果使用中有什么问题请及时与我联系。
