使用DIDatepicker

使用DIDatepicker

https://github.com/noxt/DIDatepicker

效果:

#import "DIViewController.h"
#import "DIDatepicker.h"

@interface DIViewController ()

@property (weak, nonatomic) IBOutlet DIDatepicker *datepicker;
@property (weak, nonatomic) IBOutlet UILabel *selectedDateLabel;

@end

@implementation DIViewController

- (void)viewDidLoad
{
    [super viewDidLoad];

    // 给DIDatepicker添加了相应事件
    [self.datepicker addTarget:self
                        action:@selector(updateSelectedDate)
              forControlEvents:UIControlEventValueChanged];

    // 当前月
    [self.datepicker fillCurrentMonth];
    [self.datepicker selectDateAtIndex:0];
}

- (void)updateSelectedDate
{
    NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
    formatter.dateFormat = [NSDateFormatter dateFormatFromTemplate:@"EEEEddMMMM"
                                                           options:0
                                                            locale:nil];

    self.selectedDateLabel.text = \
        [formatter stringFromDate:self.datepicker.selectedDate];
}

@end

源码其实很恶心......

DIDatepicker继承至UIControl,而UIControl继承至UIView

红色线条是在DIDatepicker.m中的drawRect:方法中动态绘制的,有着修改的余地:)

至于修改字体颜色之类的,是在DIDatepickerDateView.m中(我简单的将星期六星期天修改成了红色)

他的这种设计其实还是很合理的:)
