How to Clear IOS App Library Cache (Downloaded Images)

Question

I am working with download async images. I get a lot images from my webserver but all are temporary and I won\'t cache any of them. But the app apparently save the download

Answer 1

The cache will be emptied when it needs to be, i.e. when the application receives a Low Memory Warning. There is no reason for you to do this yourself, and there is no public API available.

NOTE
When the os manages something for you, you don't need to worry about it.

But if you really want to clear your cache then follow this

NSFileManager *filemgr;

filemgr = [NSFileManager defaultManager];

if ([filemgr removeItemAtPath: [NSHomeDirectory() stringByAppendingString:@"/Library/Caches"] error: NULL]  == YES)
    NSLog (@"Remove successful");
else
    NSLog (@"Remove failed");

[filemgr createDirectoryAtPath: [NSHomeDirectory() stringByAppendingString:@"/Library/Caches"] withIntermediateDirectories:NO attributes:nil error:nil];
