标题: ios - SDImageCache - 4.0 迁移后无法识别的选择器错误

我最近将一个项目升级到 SDWebImage 4.0，我只用它来缓存图像并在以后检索它们。在 3.x 版本上可以完美运行。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，我无法修复它。

这是我以前的 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];

这是我为 4.0 API 更新的代码，这是引发错误的代码行...

[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!

Best Answer-推荐答案

我尝试这样并且它有效，您必须 shift + cmd + k 并重新构建，必须解决此处指出的问题 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

CONSOLE OUTPUT

2017-07-11 00:55:12.146 SDWebImageSOQuestion[17275:339149] INFO: Image cached successfully!
