iOS 自定义日历.docx

1、iOS 自定义日历iOS 自定义日历大体说一下思路，核心点在于创建布局每个月的日期，点击年份月份只是刷新数据。每一个日期是一个视图，我这里用的是UIButton，通过循环添加到日期视图。获取日期一定是基于NSDate，通过NSCalendar获取到指定的某一年的某一月有多少天和第一天是星期几，这样就可以在循环中知道当前月份需要设置的初始日期位置以及需要设置的日期个数。其他就是展示和一些逻辑判断。下面贴上代码：ViewController：objc view plain copy 在CODE上查看代码片派生到我的代码片#import interface ViewController : UIVi

2、ewController end /* -分割线- */ #import ViewController.h #import HWCalendar.h interface ViewController () property (nonatomic, weak) HWCalendar *calendar; property (nonatomic, strong) UITextField *textField; end implementation ViewController - (void)viewDidLoad super viewDidLoad; self.view.backgroundCo

3、lor = UIColor blackColor; /创建控件 self creatControl; - (void)creatControl /输入框 _textField = UITextField alloc initWithFrame:CGRectMake(7, 64, 400, 44); _textField.delegate = self; _textField.layer.cornerRadius = 22; _textField.layer.masksToBounds = YES; _textField.placeholder = 请设置日期; _textField.textA

4、lignment = NSTextAlignmentCenter; _textField.backgroundColor = UIColor whiteColor; self.view addSubview:_textField; /日历 HWCalendar *calendar = HWCalendar alloc initWithFrame:CGRectMake(7, UIScreen mainScreen.bounds.size.height, 400, 396); calendar.delegate = self; calendar.showTimePicker = YES; self

5、.view addSubview:calendar; self.calendar = calendar; #pragma mark - UITextFieldDelegate - (BOOL)textFieldShouldBeginEditing:(UITextField *)textField if (_calendar.frame.origin.y != UIScreen mainScreen.bounds.size.height & _calendar) _calendar dismiss; return NO; else if (textField = _textField) _cal

6、endar show; return NO; return YES; #pragma mark - HWCalendarDelegate - (void)calendar:(HWCalendar *)calendar didClickSureButtonWithDate:(NSString *)date _textField.text = date; end HWCalendar：objc view plain copy 在CODE上查看代码片派生到我的代码片#import class HWCalendar; protocol HWCalendarDelegate - (void)calend

7、ar:(HWCalendar *)calendar didClickSureButtonWithDate:(NSString *)date; end interface HWCalendar : UIView property (nonatomic, assign) BOOL showTimePicker; /default is NO. doesnt show timePicker property (nonatomic, weak) id delegate; - (void)show; - (void)dismiss; end /* -分割线- */ #import HWCalendar.
