NNPickerField

UITextField subclasses supporting UIPickerViews as inputs (instead of the standard keyboard)

##Usage The NNPickerFields are a simple way to accept non-keyboard input from a user, imitating the known and common combo-boxes. The NNPickerFields are divided into several different classes, each handles a specific use-case:

• NNDatePickerField
• NNObjectPickerField
• NNNumberPickerField

The classes have internal documentation and are quite readable and descriptive. (Feel free to ask for explanations if not)

Every NNPickerField subclass has an option to show a UIToolbar accessory above it with an optional title and clear and close buttons:

[myNNPickerField setShowsToolBarWithTitle: @"Title" 
                     withCloseButtonTitle: @"Close ME"
                           withClearTitle: @"Cleanup"
                           withTitleColor: nil];

###NNDatePickerField The NNDatePickerField utilizes the UIDatePicker and is used for selecting dates and times. The picker supports all UIDatePickerModes: Date and time, Time, Date and Countdown:

[myDatePicker setDatePickerMode: UIDatePickerModeDateAndTime];

The picker also supports custom date formats, if no formats are provided - the system's default formats are used.

[myDatePicker setDateDisplayFormat: @"dd/MM/yy"];

The picker supports limiting date and time selection with minimum/maximum dates:

[myDatePicker setMinimumDate: [NSDate date]]; //Limits the minimum date to now.
[myDatePicker setMaximumDate: [NSDate dateWithTimeIntervalSinceNow: 60 * 60 * 24 * 7]]; //Limits the maximum date to a week from now.

###NNObjectPickerField The NNObjectPickerField is used for picking object types - objects, strings, etc. Basic usage:

[objectPickerField setItems: [NSArray arrayWithObjects: @"1", @"John", myObject]];

Notice: The NNObjectPickerField currently supports NSString and all objects that confirm to the NNSelectable protocol.

###NNNumberPickerField The NNNumberPickerField is used for picking a number from a range of numbers. Basic usage:

[myNumberPickerField showNumberRangeFromNumber:2005 toNumber:2015];

###NNPickerFieldDelegate Each NNPickerField defines a custom delegate protocol of it's own and ll custom delegate protocols conform to the generic NNPickerFieldDelegate that informs the delegate of clicks on the 'close' and 'clear' buttons. The custom delegate protocols ask wether a change in selection should occur and also informs the delegate of changes in selection.
