iOS自定义日历控件

在我们开发的过程中,难免会遇到一些自定义系统控件的问题,不要发愁,把它当做一个游戏来做就可以了!!

不说废话,开始上代码了!!!!!

首先,这里使用的是view来进行自定义日历的,主要使用的UICollectionView控件

1、声明文件,在.h中定义代码块,往vc中传值使用

#import

typedefvoid(^selectDate)(NSString*selectedDate);

@interfaceDBSelectedCalenderView :UIView

@property(nonatomic,copy) selectDate date;

@end

2、接下来就是主要的.m中的实现了(做好准备了吗?)

#import "DBSelectedCalenderView.h"

#import "DBCalenderCollectionViewCell.h"        //单元格

@interface DBSelectedCalenderView()

@property(nonatomic,strong) UILabel *today;

@property(nonatomic,strong)UICollectionView*calenderCollectionView;

@property(nonatomic,strong) UICollectionViewFlowLayout *layout;

@end

#define cellWidth30        //单元格宽高

#define margin ([UIScreen mainScreen].bounds.size.width - cellWidth *7) /8    //间距

@implementationDBSelectedCalenderView

-(instancetype)initWithFrame:(CGRect)frame{

if(self= [superinitWithFrame:frame]) {

self.backgroundColor = [UIColor whiteColor];

[selfaddSubview:self.today];

[self addSubview:self.calenderCollectionView];

UIView *vi = [[UIView alloc]init];

vi.backgroundColor = [UIColor groupTableViewBackgroundColor];

[selfaddSubview:vi];

vi.sd_layout.topSpaceToView(self.calenderCollectionView, margin).leftSpaceToView(self, 0).rightSpaceToView(self, 0).bottomSpaceToView(self, 0);

// 注册collectionViewcell:WWCollectionViewCell是我自定义的cell的类型

[self.calenderCollectionView registerClass:[DBCalenderCollectionViewCell class] forCellWithReuseIdentifier:@"DBCalenderCollectionViewCell"];

NSDateFormatter *formatter = [[NSDateFormatter alloc] init];

[formattersetDateFormat:@"dd"];

NSInteger nowDay = [[formatter stringFromDate:[NSDate date]] integerValue];

[_calenderCollectionView selectItemAtIndexPath:[NSIndexPath indexPathForItem:nowDay - 1 inSection:0] animated:YES scrollPosition:UICollectionViewScrollPositionNone];

[self.calenderCollectionView reloadData];

}

return self;

}

-(NSInteger)numberOfSectionsInCollectionView:(UICollectionView*)collectionView{

return 1;

}

-(NSInteger)collectionView:(UICollectionView*)collectionView numberOfItemsInSection:(NSInteger)section{

return [self getNumberOfDaysInMonth];

}

-(UICollectionViewCell*)collectionView:(UICollectionView*)collectionView cellForItemAtIndexPath:(NSIndexPath*)indexPath{

DBCalenderCollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:@"DBCalenderCollectionViewCell" forIndexPath:indexPath];

cell.layer.masksToBounds = YES;

cell.layer.cornerRadius = 4;

NSDateFormatter *formatter = [[NSDateFormatter alloc] init];

[formattersetDateFormat:@"dd"];

NSInteger nowDay = [[formatter stringFromDate:[NSDate date]] integerValue];

NSIndexPath *inde = [NSIndexPath indexPathForItem:nowDay - 1 inSection:0];

DBCalenderCollectionViewCell *defaultCell = (DBCalenderCollectionViewCell *)[collectionView cellForItemAtIndexPath:inde];

//    defaultCell.backgroundColor = [UIColor yellowColor];

defaultCell.layer.borderColor = HTitColor.CGColor;

defaultCell.layer.borderWidth=1;

cell.nowDay.text= [NSStringstringWithFormat:@"%ld",indexPath.row+1];

returncell;

}

-(void)collectionView:(UICollectionView*)collectionView didSelectItemAtIndexPath:(NSIndexPath*)indexPath{

NSDateFormatter *formatter = [[NSDateFormatter alloc] init];

[formattersetDateFormat:@"dd"];

NSInteger nowDay = [[formatter stringFromDate:[NSDate date]] integerValue];

NSIndexPath *inde = [NSIndexPath indexPathForItem:nowDay - 1 inSection:0];

DBCalenderCollectionViewCell *defaultCell = (DBCalenderCollectionViewCell *)[collectionView cellForItemAtIndexPath:inde];

defaultCell.layer.borderColor = [UIColor clearColor].CGColor;

defaultCell.layer.borderWidth=1;

DBCalenderCollectionViewCell *cell = (DBCalenderCollectionViewCell *)[collectionView cellForItemAtIndexPath:indexPath];

cell.layer.borderColor = HTitColor.CGColor;

cell.layer.borderWidth = 1;

NSDateFormatter *formatterr = [[NSDateFormatter alloc] init];

[formatterrsetDateFormat:@"yyyy-MM"];

NSString*nowMonth = [formatterrstringFromDate:[NSDatedate]];

NSString *str = [nowMonth stringByAppendingString:[NSString stringWithFormat:@"-%@",cell.nowDay.text]];

NSLog(@"%@",str);

if(self.date) {

self.date(str);

}

}

-(void)collectionView:(UICollectionView*)collectionView didDeselectItemAtIndexPath:(NSIndexPath*)indexPath{

DBCalenderCollectionViewCell *cell = (DBCalenderCollectionViewCell *)[collectionView cellForItemAtIndexPath:indexPath];

cell.layer.borderColor = [UIColor clearColor].CGColor;

cell.layer.borderWidth = 1;

}

/** 每个cell的尺寸*/

- (CGSize)collectionView:(UICollectionView*)collectionView layout:(UICollectionViewLayout*)collectionViewLayout sizeForItemAtIndexPath:(NSIndexPath*)indexPath{

return CGSizeMake(cellWidth, cellWidth);

}

#pragma mark - setter and getter

-(UILabel*)today{

if(!_today) {

_today = [[UILabel alloc]initWithFrame:CGRectMake(20, 20, self.frame.size.width - 20, 50)];

NSDateFormatter *formatter = [[NSDateFormatter alloc] init];

[formattersetDateFormat:@"yyyy-MM-dd"];

NSDateFormatter *outputFormatter=[[NSDateFormatter alloc]init];

[outputFormattersetDateFormat:@"EEEE-MMMM-d"];

NSString*outputDateStr=[outputFormatterstringFromDate:[NSDatedate]];

NSArray*weekArray=[outputDateStrcomponentsSeparatedByString:@"-"];

_today.numberOfLines = 2;

_today.text = [NSString stringWithFormat:@"%@\n%@",[formatter stringFromDate:[NSDate date]],[self cTransformFromE:[weekArray objectAtIndex:0]]];

}

return _today;

}

-(UICollectionView*)calenderCollectionView{

if (!_calenderCollectionView) {

_calenderCollectionView = [[UICollectionView alloc]initWithFrame:CGRectMake(0, 70, self.frame.size.width, 150 + 5 * margin) collectionViewLayout:self.layout];

_calenderCollectionView.delegate = self;

_calenderCollectionView.dataSource = self;

_calenderCollectionView.scrollEnabled = NO;

_calenderCollectionView.backgroundColor = [UIColor whiteColor];

}

return _calenderCollectionView;

}

-(UICollectionViewFlowLayout *)layout{

if(!_layout) {

_layout = [[UICollectionViewFlowLayout alloc]init];

_layout.itemSize = CGSizeMake(cellWidth, cellWidth);

//四周边距

_layout.sectionInset = UIEdgeInsetsMake(margin, margin, margin, margin);

_layout.minimumInteritemSpacing = margin;

_layout.minimumLineSpacing = margin;

//设置滑动方向

_layout.scrollDirection = UICollectionViewScrollDirectionVertical;

}

return _layout;

}

// 获取当月的天数

- (NSInteger)getNumberOfDaysInMonth

{

NSCalendar * calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSCalendarIdentifierGregorian]; // 指定日历的算法 NSGregorianCalendar - ios 8

NSDate* currentDate = [NSDatedate];

NSRange range = [calendar rangeOfUnit:NSCalendarUnitDay  //NSDayCalendarUnit - ios 8

inUnit:NSCalendarUnitMonth//NSMonthCalendarUnit - ios 8

forDate:currentDate];

returnrange.length;

}

//转换英文为中文

-(NSString*)cTransformFromE:(NSString*)theWeek{

NSString*chinaStr;

if(theWeek){

if([theWeekisEqualToString:@"Monday"]){

chinaStr =@"星期一";

}elseif([theWeekisEqualToString:@"Tuesday"]){

chinaStr =@"星期二";

}elseif([theWeekisEqualToString:@"Wednesday"]){

chinaStr =@"星期三";

}elseif([theWeekisEqualToString:@"Thursday"]){

chinaStr =@"星期四";

}elseif([theWeekisEqualToString:@"Friday"]){

chinaStr =@"星期五";

}elseif([theWeekisEqualToString:@"Saturday"]){

chinaStr =@"星期六";

}elseif([theWeekisEqualToString:@"Sunday"]){

chinaStr =@"星期日";

}

}

returnchinaStr;

}

当然,还有主要的就是自定义单元格哦!!   小伙伴们一定不要忘记这致命的一点哦!!

.h

#import

@interfaceDBCalenderCollectionViewCell :UICollectionViewCell

@property(nonatomic,strong) UILabel *nowDay;

@end

.m

#import "DBCalenderCollectionViewCell.h"

@interface DBCalenderCollectionViewCell()

@end

@implementationDBCalenderCollectionViewCell

-(instancetype)initWithFrame:(CGRect)frame{

if(self= [superinitWithFrame:frame]) {

[self.contentView addSubview:self.nowDay];

}

return self;

}

-(UILabel*)nowDay{

if(!_nowDay) {

_nowDay = [[UILabel alloc]initWithFrame:self.contentView.frame];

_nowDay.textColor=HBgColor;

_nowDay.textAlignment = NSTextAlignmentCenter;

}

return _nowDay;

}

@end

OK,这样一个自定义日历控件就出来了,其实好多东西本身并不难,是我们自己想复杂了,把它当做游戏,那样会很有乐趣而且很有效果哦!!!!!!
