IOS时间选择器UIPickerView，ios8中UIView替代UIActionSheet
以前在网上下了个时间选择器Demo，由于封装成UIActionSheet类型，而ios8弃用了UIActionSheet和UIAlertView，不得不对代码进行修改。将封装的UIActionSheet改为UIView，为了多态初始化时添加了枚举（几个时间选择器样式）。
以前下载的Demo网址实在找不到了，对原作者表示抱歉。
参考：DateTimeYearPickerView，UIActionSheet上添加UIPickerView iOS8替换方案
项目：点击下载
UIActionSheet改为UIView核心代码为以下几个方法：
- (void)showInView:(UIView *)view; // UIPicker显示
-(void)hidePickerView; // UIPicker隐藏
- (UIViewController *)viewController; // 通过UIView查找UIViewController
#import "DateTimePickerView.h"
