Question

我最近将一个项目升级到SDWebImage 4.0，我只用它来缓存图像然后检索它们。如果这在3.x版本上完美运行。迁移后我现在收到以下错误...

-[SDImageCache storeImage:forKey:toDisk:completion:]: unrecognized selector sent to instance 0x174097cf0

这似乎应该是一个简单的错误来解决，但经过多次尝试，我无法解决它。

以下是我以前的3.x API代码......

@property (strong, nonatomic) SDImageCache *imageCache;
- (SDImageCache *)imageCache {

    if (!_imageCache) {
        _imageCache = [[SDImageCache alloc] initWithNamespace:NAME_SPACE_IMAGE_CACHE];

    }

    return _imageCache;
}


    [self.imageCache storeImage:[UIImage imageWithContentsOfFile:imageData.imageURL.path] forKey:imageData.imageURL.absoluteString toDisk:YES];

这是我更新的4.0 API代码，这是抛出错误的代码行...

[self.imageCache storeImage:[UIImage imageWithContentsOfFile:imageData.imageURL.path] forKey:imageData.imageURL.absoluteString toDisk:YES completion:^{
                                    NSLog(@"INFO: Image cached successfully!");
                                }];

有人可以帮助澄清问题所在吗？

提前致谢！

我尝试这样并且它可以工作，你必须移动+ cmd + k然后重新构建，必须解决问题，如此处所指出的那样https://github.com/rs/SDWebImage/issues/1602

#import "ViewController.h"

@interface ViewController ()
@property SDImageCache * imageCache;
@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];

    self.imageCache = [SDWebImageManager sharedManager].imageCache;
    // Do any additional setup after loading the view, typically from a nib.
    [_imageCache storeImage:[UIImage imageNamed:@"test"] forKey:@"testKey" toDisk:YES completion:^{
        NSLog(@"INFO: Image cached successfully!");
    }];

}


- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}


@end
