• 一个轻量级日历小框架。
• 可随意插拔部分视图、任意修改日历展现样式。

Tips:

• 1.该日历提供单月、多月两种样式可随意切换。
• 2.自定义样式时就像给tableView自定义cell一样简单。
• 3.日历面板的宽和高是由内部cell决定的，随着改变cell大小，日历面板的大小也会跟着改变。
• 4.有关日历的获取方法都抽取在NSDate+GYDateExtension分类里，应用该分类还可以轻松操作日期数据。

GYCalendar的使用

• 方法一:通过cocoapods -> pod 'GYCalendar'
• 方法二:Download ZIP -> 把GYCalendar文件夹中的所有文件拽入项目中,主头文件为：#import "GYCalendar.h"

Example

1.最简单的日历

    // 初始化
    GYCalendarView *calendarView = [GYCalendarView calendarView];
    calendarView.frame = CGRectMake(HMargin, VMargin - 40, 0, 0);
    [self.view addSubview:calendarView];

2.多月样式的日历

    GYCalendarView *calendarView = [GYCalendarView calendarView];
    // 设置为多月样式
    calendarView.calendarViewStyle = GYCalendarViewStyleMulMonth;
    calendarView.frame = CGRectMake(HMargin, 65, 0, 0);
    [self.view addSubview:calendarView];

3.自定义日历的头部样式

    // 初始化
    GYCalendarView *calendarView = [GYCalendarView calendarView];
    calendarView.frame = CGRectMake(HMargin, VMargin, 0, 0);
    [self.view addSubview:calendarView];
    self.calendarView = calendarView;
    // 自定义HeaderView
    [self setupCustomHeaderView];       

//自定义headerView

[self.calendarView hideHeaderView];
[self.calendarView calendarScrollEnable:NO];

UILabel *headerView = [[UILabel alloc] init];
headerView.userInteractionEnabled = YES;
headerView.tag = headerTag;
headerView.backgroundColor = [UIColor redColor];
headerView.frame = CGRectMake(HMargin, VMargin - 40, 315, 40);
headerView.text = [NSString stringWithFormat:@"%@",[self.calendarView.fireDate gy_dateByFormat:@"yyyy-MM-dd"]];
headerView.textColor = [UIColor whiteColor];
headerView.textAlignment = NSTextAlignmentCenter;
[self.view addSubview:headerView];

// 初始化左/右Label
UILabel *preLabel = [self setupLabel:@"上个月" isLeft:YES];
UILabel *nextLabel = [self setupLabel:@"下个月" isLeft:NO];

// 点击事件
UITapGestureRecognizer *preTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(preTap:)];
UITapGestureRecognizer *nextTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(nextTap:)];
[preLabel addGestureRecognizer:preTap];
[nextLabel addGestureRecognizer:nextTap];

[headerView addSubview:preLabel];
[headerView addSubview:nextLabel];

// 初始化左/右Label (UILabel *)setupLabel:(NSString *)labelText isLeft:(BOOL)isLeft

UILabel *label = [[UILabel alloc] init];
label.text = labelText;
label.textAlignment = NSTextAlignmentCenter;
label.textColor = [UIColor whiteColor];
label.backgroundColor = [UIColor blueColor];
CGFloat x = isLeft ? 0 : (315 - 60);
label.frame = CGRectMake(x, 0, 60, 40);
label.userInteractionEnabled = YES;

return label;

// 左侧label点击事件 (void)preTap:(UITapGestureRecognizer *)tap

UILabel *headerView = [self.view viewWithTag:headerTag];
headerView.text = [NSString stringWithFormat:@"%@",[[self.calendarView preMonth] gy_dateByFormat:@"yyyy-MM-dd"]];

}

// 右侧label点击事件 (void)nextTap:(UITapGestureRecognizer *)tap

UILabel *headerView = [self.view viewWithTag:headerTag];
headerView.text = [NSString stringWithFormat:@"%@",[[self.calendarView nextMonth] gy_dateByFormat:@"yyyy-MM-dd"]];

4.自定义日历Cell

GYCalendarView *calendarView = [GYCalendarView calendarView];
// 设置起始日期
calendarView.fireDate = [NSDate dateWithTimeIntervalSinceNow:40 * 24 * 60 * 60];
calendarView.frame = CGRectMake(HMargin, 65, 0, 0);
// 称为代理
calendarView.delegate = self;
// 注册cell
[calendarView registerNib:[UINib nibWithNibName:NSStringFromClass([MyDateCell class]) bundle:nil] forCellWithReuseIdentifier:ID];
[self.view addSubview:calendarView];
self.calendarView = calendarView;

// 自定义日历Cell展现逻辑
for (int i = 0; i < 10; i++) {
    MyDateModel *myDateModel = [[MyDateModel alloc] init];
    myDateModel.date = [NSDate dateWithTimeIntervalSinceNow:i * 24 * 60 * 60];
    [self.tickets addObject:myDateModel];
}

// 设置cell大小 (CGSize)calendarViewCellSize

return CGSizeMake(45, 55);

// 返回自定义cell (GYDateCell *)calendarView:(GYCalendarView *)calenderView dateModel:(GYDateModel *)dateModel cellForItemAtIndexPath:(NSIndexPath *)indexPath

// 取cell
MyDateCell *dateCell = (MyDateCell *)[calenderView dequeueReusableCellWithReuseIdentifier:ID forIndexPath:indexPath];
dateCell.dateModel = dateModel;

for (MyDateModel *myDateModel in self.tickets) {
    if ([myDateModel.date gy_isEqualDay:dateModel.date]) {
        dateCell.myDateModel = myDateModel;
        return dateCell;
    }
}
return dateCell;

}

// 选中cell事件 (void)calendarView:(MyDateCell *)dateCell didSelectItemAtIndexPath:(NSIndexPath *)indexPath

MyDateModel *myDateModel = dateCell.myDateModel;
myDateModel.isSelected = !myDateModel.isSelected;
dateCell.myDateModel = myDateModel;

// 切换样式 (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event

if (self.calendarView.calendarViewStyle == GYCalendarViewStyleMulMonth) {
    self.calendarView.calendarViewStyle = GYCalendarViewStyleMonth;
} else {
    self.calendarView.calendarViewStyle = GYCalendarViewStyleMulMonth;
}
