Disable Past Date in UIDatePicker in IPhone Objective C

问题

I am new to Objective C and IPhone development.

I am using a UIDatePicker in my IPhone Application and my requirement is to allow the user to choose the future date only from the DatePicker.

To do this i want to disable past date & time in DatePicker only instead of putting a compare validation in the code.

Is this possible or there is an option to disable the past date in the DatePicker control itself.

回答1:

Did you try this

[picker setMinimumDate: [NSDate date]];

回答2:

Use the following line,to disable the previous dates of an UIDatePicker.

[picker setMinimumDate: [NSDate date]];

The current date is displayed as shown below

回答3:

For Swift :

let todaysDate = Date()

datePicker.minimumDate = todaysDate

It will not let the user to pick a date older than Today

OR

Or, if you want to reduce the code, use following way:

datePicker.minimumDate = Date()
