IOS custom Date and data source selection control

Demand

App development often has a date selection (such as birthdays, sleep timing, etc.) or provincial urban choice such functions, usually the UI does not use the control in the UI alone, but on the basis of Uipickerview to add a cancellation and Confirm button features to support the common selection of data format
The control integrates YYYY-MM-DD, yyyy-mm, HH MM, provincial and municipal, provincial and municipal cascading, custom data sources (2 columns), custom data sources (3 columns), and many other formats, that is, support Uitextfield and event triggering mechanisms support Xib also support pure code effect diagram

Binding Custom Classes

Drag the line and set the mode

@interface Viewcontroller ()
@property (weak, nonatomic) Iboutlet Xxtextfield *textfield;
@end

@implementation Viewcontroller

-(void) viewdidload {
    [super viewdidload];
    _textfield.mode = xxpickerviewmodedate;
}

@end
