How To Clear Cache Memory When New ViewController Call In IOS 7?

Question

I use NSURLConnection to send request on server NSURLConnection increase cache memory and application crash due to low memory. I use this code for clearing Cache:

[[NSURLCache sharedURLCache] removeAllCachedResponses];

But in iOS 7 this code doesn't work any more. Does anyone have any idea how to clear cache memory ?

you can convert your code to arc by clicking edit->refractor->convert to arc in xcode.then try with the same code. — gunas, Feb 28 '14 at 07:00

You can exclude third part libraries from arc, refer to :http://stackoverflow.com/questions/8040629/ios5-arc-what-is-the-compiler-flag-to-exclude-a-file-from-arc — Danyun Liu, Feb 28 '14 at 07:30

You can create an NSURLCache with a specific memory or disk usage limitation with -setDiskCapacity: or -setMemoryCapacity:. You can clear the cache in UIViewController's -viewWillDisappear: or -viewDidDisappear:.

i use [[NSURLCache sharedURLCache] removeAllCachedResponses] code in viewWillDisappear , viewDidDisappear and viewDidLoad but this code not working in IOS7. In IOS7 object release automatically if we use ARC but problem is i use non arc approach. – Rizwan Shah Feb 28 '14 at 07:10
