I found how to clear cache, before app starts. Add this in didFinishLaunchingWithOptions:
|
1 |
[[NSURLCache sharedURLCache] removeAllCachedResponses]; |
It is possible to remove Cookies and cache for one request. Read it here.
I found two good solutions in StackOverflow:
|
1 2 |
[existingArray replaceObjectsInRange:NSMakeRange(0,0) withObjectsFromArray:newArray]; |
And the second one:
|
1 2 |
NSIndexSet *indexes = [NSIndexSet indexSetWithIndexesInRange: (NSRange) {0, [newArray count]}]; [existingArray insertObjects: newArray atIndexes: indexes]; |
