Question

我面临着获取uicollectionViewCell文本的问题。当我选择一个特定的细胞。我正在使用各种代码，但没有人对我有用。所以，请帮我解决这个问题。

Answer 1

如果您使用默认的UICollectionView课程，那么您可以使用这行代码。

UICollectionView *cell //use alloc etc

cell.textLabel.text //this line return the text of collectionviewcell. as in UITableView

Answer 2

我相信您必须创建自定义UICollectionViewCell类...

使用UICollectionView的一种简单方法是创建一个日历月视图，其中包含多个UICollectionViewCells作为月视图中的不同日期。

下面是UICollectionViewCell与UICollectionView使用的基本实现：

CBCalendarCell.h


#import <UIKit/UIKit.h>
@interface CBCalendarCell : UICollectionViewCell    
@property UIView *circleView;    
@property UIView *selectedView;    
@property UILabel *dateLabel;
@property UIView *eventView;    
@end



CBCalendarCell.m

#import "CBCalendarCell.h"
#import "CBConstants.h"

@implementation CBCalendarCell
- (id)initWithFrame:(CGRect)frame
{
    if (!(self = [super initWithFrame:frame])) return nil;

    self.backgroundColor = cellBackgroundColor;

    self.dateLabel = [[UILabel alloc]initWithFrame:CGRectMake(0, 0, frame.size.width, frame.size.height * labelToCellRatio)];
    self.dateLabel.textAlignment = NSTextAlignmentCenter;

    self.eventView = [[UIView alloc] initWithFrame:CGRectMake(self.dateLabel.frame.size.width / 2.0f - 1.5f,
                                                              self.dateLabel.frame.origin.y + self.dateLabel.frame.size.height - 5,
                                                              3, 3)];
    [[self.eventView layer] setCornerRadius:1.5f];
    [self.eventView setBackgroundColor:cellEventViewColor];

    CGRect labelFrame = self.dateLabel.frame;
    CGSize labelSize = labelFrame.size;

    CGPoint origin;
    int length;
    if (labelSize.width > labelSize.height) {
        origin.x = (labelSize.width - labelSize.height * circleToCellRatio) / 2;
        origin.y = (labelSize.height * (1 - circleToCellRatio)) / 2;
        length = labelSize.height * circleToCellRatio;
    }
    else{
        origin.x = (labelSize.width * (1 - circleToCellRatio)) / 2;
        origin.y = (labelSize.height - labelSize.width * circleToCellRatio) / 2;
        length = labelSize.width * circleToCellRatio;
    }

    self.circleView = [[UIView alloc] initWithFrame:CGRectMake(origin.x, origin.y, length, length)];

    self.circleView.layer.cornerRadius = length / 2;
    self.circleView.backgroundColor = currentDateCircleColor;

    self.selectedView = [[UIView alloc] initWithFrame:CGRectMake(origin.x, origin.y, length, length)];

    self.selectedView.layer.cornerRadius = length / 2;
    self.selectedView.backgroundColor = selectedDateCircleColor;

    [self.viewForBaselineLayout addSubview:self.circleView];
    [self.viewForBaselineLayout addSubview:self.selectedView];
    [self.viewForBaselineLayout addSubview:self.dateLabel];
    [self.viewForBaselineLayout addSubview:self.eventView];
    return self;
}

@end

在UICollectionView中注册自定义UICollectionViewCell，如下所示：

// 'calendar' is the UICollectionView instance name
[calendar registerClass:[CBCalendarCell class] forCellWithReuseIdentifier:@"cellIdentifier"];

然后在- (UICollectionViewCell *)collectionView:cellForItemAtIndexPath:中配置单元格：

- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
    CBCalendarCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:@"cellIdentifier" forIndexPath:indexPath];
    ...
    ...
    cell.circleView.hidden = YES;
    cell.selectedView.hidden = NO;
    cell.dateLabel.text = @"Text";
    cell.eventView.hidden = NO;
    ...
    ...
    return cell;
}
