可以支持字数限制

[!] CocoaPods could not find compatible versions for pod "UITextView-WZB":
In Podfile:
UITextView-WZB (~> 1.1.1)

Specs satisfying the UITextView-WZB (~> 1.1.1) dependency were found, but they required a higher minimum deployment target.

// if (self.placeholderView) {
// NSArray *propertys = @[@"frame", @"bounds", @"font", @"text", @"textAlignment", @"textContainerInset"];
// for (NSString *property in propertys) {
// [self removeObserver:self forKeyPath:property];
// }
// }

里面这段代码 Time一直无限叠加 直至卡死 释放不掉

右下角加一个统计字数 类似于这样最大字数10 2/10

字数限制有了吗?

在创建的时候需要设置placeholder和默认text时，存在placeholder的文字和text都显示的问题。

是否可以优化？
因为我没有设置placeholder，回调方法一直没有相应。还调试了半天。

求问怎么改变cell的高度

这样就会和MJRefresh 有冲突了，导致下拉刷新那个view 直接位移了
