我正在学习将 CocoaPods 集成到我的项目中。

我已经下载 MCSwipeTableView 并将其安装到我的项目中。

我已经坚持了几个小时，并阅读了这个问题的其他相关答案。

这是发生“No visible @interface”错误的行:

UIView *checkView = [self viewWithImageName:@"check"];

我在这里做错了什么？

#import "PhotosTableViewController.h"
#import "MCSwipeTableViewCell.h"

@interface PhotosTableViewController () <MCSwipeTableViewCellDelegate, UIAlertViewDelegate> {

    NSMutableArray *photos;

}

@property (nonatomic, assign) NSUInteger nbItems;
@property (nonatomic, strong) MCSwipeTableViewCell *cellToDelete;

@end

@implementation PhotosTableViewController

- (id)initWithStyle:(UITableViewStyle)style
{
    self = [super initWithStyle:style];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];

    self.title = @"Photos";

    // Uncomment the following line to preserve selection between presentations.
    // self.clearsSelectionOnViewWillAppear = NO;

    // Uncomment the following line to display an Edit button in the navigation bar for this view controller.
    // self.navigationItem.rightBarButtonItem = self.editButtonItem;


    // create array
    photos = [[NSMutableArray alloc]init];

    Photo *pic = [[Photo alloc]init];
    pic.names = @"Lemon Cover";
    pic.fileName = @"lemon cover";
    pic.notes = @"This is the ebook title picture of my original eBook that was never published due to various reasons.";

    [photos addObject:pic];

    pic = [[Photo alloc]init];
    pic.names = @"Off Camera Celebrity";
    pic.fileName = @"offcameralogo4";
    pic.notes = @"My first idea that I really pursued on my own. It started as one thing and quickly led to much more.";
    [photos addObject:pic];

    pic = [[Photo alloc]init];
    pic.names = @"Soup Recipe Book";
    pic.fileName = @"Soup Ebook Cover";
    pic.notes = @"This was the best non-published ebook I had that Amazon shut down again.";
    [photos addObject:pic];

最佳答案

首先，这是一个警告，而不是错误。但当您的应用执行该行代码时，它可能会出错。

对象 self 没有方法 viewWithImageName。您需要将该方法添加到类中。

Google 快速搜索发现有人在 GitHub 上使用这种方法。只需将其添加到您的类(class)即可:

- (UIView *)viewWithImageName:(NSString *)imageName {
    UIImage *image = [UIImage imageNamed:imageName];
    UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
    imageView.contentMode = UIViewContentModeCenter;
    return imageView;
}

关于ios - 没有可见的@interface 'PhotosTableViewController' 声明选择器 'viewWithImageName'，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/22900009/
