iOS 7 has a bug (or made a design decision which goes against the documentation) to set the cookie policy of NSURLConnections to whatever the user has set their cookie preferences to via Settings -> Safari. This simple method resets the cookie policy to accept always. Apple documentation for cookieAcceptPolicy: https://developer.apple.com/librar…
- (void)takeControlOfTheCookies
{
[[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookieAcceptPolicy:NSHTTPCookieAcceptPolicyAlways];
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[self takeControlOfTheCookies];

Haven't done much with dispatch_io yet so I'd appreciate a few more eyeballs on this. Am I closing things correctly in all error conditions? Are there other knobs I could change to make things even faster? (I know I've been lazy on the NSError's)
static NSData *PSPDFCalculateSHA256FromFileURL(NSURL *fileURL, CC_LONG dataLength, NSError **error) {
NSCParameterAssert(fileURL);
dispatch_queue_t shaQueue = dispatch_queue_create("com.pspdfkit.sha256-queue", DISPATCH_QUEUE_SERIAL);
__block dispatch_io_t readChannel;
void (^processIntError)(int intError) = ^(int intError) {
if (intError != 0) {
PSPDFLogWarning(@"Stream error: %d", intError);
if (error) *error = [NSError errorWithDomain:@"SHA256Error" code:100 userInfo:@{NSLocalizedDescriptionKey: @"failed to open file for calculating SHA256."}];
