11.UIDatePicker using tutorial two. 11.1 Date Range

You can specify the date range to use by setting the Mininumdate and Maxinumdate properties. If a user attempts to scroll to a date beyond this range, the dial rolls back to the most recent valid date. Two methods require the NSDate object as a parameter:

nsdate* mindate = [[NSDate alloc]initwithstring:@ "1900-01-01 00:00:00-0500"];

nsdate* maxdate = [[NSDate alloc]initwithstring:@ "2099-01-01 00:00:00-0500"];

Datepicker.minimumdate = MinDate;

Datepicker.maximumdate = MaxDate;

11.2 If any one of the two date range properties is not set, the default behavior will allow the user to select any past or future date. This is useful in some cases, for example, when you choose a birthday, it can be any date in the past, but terminates with the current date. If you want to set the date that is displayed by default, you can use the Date property: Datepicker.date = MinDate; 11.3 In addition, you can also use the SetDate method. If you select Use animation, the dial will scroll to the date you specify:

[DatePicker setdate:maxdate Animated:yes];
