これは、この種のエラーが発生しているコードです。何が問題なのかわからない。
NSString *imageURL = currentData.imageLink;
NSData *imageData = [myCache valueForKey:imageURL];
if (imageData != nil) {
[cell.imageShow setImage:[UIImage imageWithData:imageData]];
} else {
NSData *dataToCache = [NSData dataWithContentsOfURL:[NSURL URLWithString:imageURL]];
[myCache setObject:dataToCache forKey:imageURL];
