Answer 1

There are private SDImageCache methods to get filesystem path to cached image. We can make these methods public with a category. Just put the code below into the, say, SDImageCache+Private.h and add it to your project:

#import "SDImageCache.h"

@interface SDImageCache (PrivateMethods)

- (NSString *)defaultCachePathForKey:(NSString *)key;
- (NSString *)cachedFileNameForKey:(NSString *)key;

@end

I had a similar problem, see: SDWebImage showing placeholder for images in cache

Basically I forked the project to resolve this.

Update:

You can just do this to avoid the flickering (this works with the master branch of the project):

[imageView setImageWithURL:url placeholderImage:imageView.image options:0 
 progress:^(NSUInteger receivedSize, long long expectedSize) {
        imageView.image = [UIImage imageNamed:@"QuestionMarkFace.png"];
 } completed:nil];
