iphone的日期選擇器

Question

我如何定製UIDatePicker以僅顯示時間？有一個現有模式顯示日，月和年，但我想擺脫一天的部分。

Answer 1

您可以設置模式，無論是時間，日期，日期和時間，還是在界面構建器中倒數計時器。

在代碼中你想setDatePickerMode和值：

typedef NS_ENUM(NSInteger, UIDatePickerMode) { 
    UIDatePickerModeTime,   // Displays hour, minute, and optionally AM/PM designation depending on the locale setting (e.g. 6 | 53 | PM) 
    UIDatePickerModeDate,   // Displays month, day, and year depending on the locale setting (e.g. November | 15 | 2007) 
    UIDatePickerModeDateAndTime, // Displays date, hour, minute, and optionally AM/PM designation depending on the locale setting (e.g. Wed Nov 15 | 6 | 53 | PM) 
    UIDatePickerModeCountDownTimer // Displays hour and minute (e.g. 1 | 53) 
};
