Please note: This API is currently unsupported, and should really only be used in a safe testing environment. For further details, take a look at this CocoaNetics article.
[NSURLRequest setAllowsAnyHTTPSCertificate:YES forHost:[url host]];
will allow you to ignore certificate errors. You will also need to add the following to the beginning of your file to grant you access to these private APIs:
@interface NSURLRequest (DummyInterface)
+ (BOOL)allowsAnyHTTPSCertificateForHost:(NSString*)host;
+ (void)setAllowsAnyHTTPSCertificate:(BOOL)allow forHost:(NSString*)host;
