IOS時間選擇器UIPickerView，ios8中UIView替代UIActionSheet
阿新 • • 發佈：2019-01-05
以前在網上下了個時間選擇器Demo，由於封裝成UIActionSheet型別，而ios8棄用了UIActionSheet和UIAlertView，不得不對程式碼進行修改。將封裝的UIActionSheet改為UIView，為了多型初始化時添加了列舉（幾個時間選擇器樣式）。
以前下載的Demo網址實在找不到了，對原作者表示抱歉。
專案：點選下載
UIActionSheet改為UIView核心程式碼為以下幾個方法：
- (void)showInView:(UIView *)view; // UIPicker顯示
-(void)hidePickerView; // UIPicker隱藏
- (UIViewController
