would you like to handle cache in disk operation?
You know some code like above-

(NSData_)dataForKey:(NSString_)key {
if([self hasCacheForKey:key]) {
return [NSData dataWithContentsOfFile:cachePathForKey(key) options:0 error:NULL];
} else {
for(NSInvocationOperation* operation in [diskOperationQueue operations]){
NSInvocation *invocation=[operation invocation];
NSString *path=nil;
NSData *data=nil;
[invocation getArgument:&path atIndex:3];
if([path hasSuffix:key]){
[invocation getArgument:&data atIndex:2];
return data;
}
}
return nil;
}
}
