编辑collectionViewCell

Question

我试图在点击后更改特定的CollectionViewCell。我创建了一个自定义单元格：

projectCell.h：

#import <UIKit/UIKit.h>

@interface ProjectCell : UICollectionViewCell
@property (weak, nonatomic) IBOutlet UILabel *projectLabel;
@property (weak, nonatomic) IBOutlet UILabel *projectCount;
@property (weak, nonatomic) IBOutlet UITextField *projectTextField;

@end

projectCell.m：

#import "ProjectCell.h"
#import "QuartzCore/CALayer.h"

@implementation ProjectCell
{
BOOL editMode;
}

- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
    // Initialization code
}
return self;
}

-(void)awakeFromNib {
// Custom initial code
}

-(void)editProject {
if (editMode == YES) {
    // disable editMode and update the project cell
    editMode = NO;
    _projectTextField.hidden = YES;
} else if (editMode == NO) {
    // Enable editMode and update the project cell
    editMode = YES;
    _projectTextField.hidden = NO;
}
}

/*
// Only override drawRect: if you perform custom drawing.
// An empty implementation adversely affects performance during animation.
- (void)drawRect:(CGRect)rect
{
// Drawing code
}
*/

@end

我试图像这样访问它：

- (void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:     (NSIndexPath *)indexPath
{
// Get the tapped cell
ProjectCell *projectCell = (ProjectCell *)[collectionView cellForItemAtIndexPath:indexPath];

// Run method
[projectCell editProject];
}

但是我在构建时遇到错误：

没有可见的@interface for＆＃39; ProjectCell声明选择器＆＃39; editProject＆＃39;

我在这里做错了什么？

非常感谢您的帮助！

我认为您需要在公共空间（标题中）声明您的功能。

#import <UIKit/UIKit.h>

@interface ProjectCell : UICollectionViewCell
@property (weak, nonatomic) IBOutlet UILabel *projectLabel;
@property (weak, nonatomic) IBOutlet UILabel *projectCount;
@property (weak, nonatomic) IBOutlet UITextField *projectTextField;

-(void)editProject;

@end
