Creating a Hit List URL with + symbols in query items properly encoded

	- (NSURL )hitListURLWithTaskTitle:(NSString )title {
	// Basic URL as a starting point
	NSURLComponents *components = [NSURLComponents componentsWithString:@"thehitlist:///inbox/tasks"];

	components.queryItems = @[
	[NSURLQueryItem queryItemWithName:@"method" value:@"POST"],
	[NSURLQueryItem queryItemWithName:@"title" value:title]
	];

	// NSURLQueryItem has encoded any spaces as %20 which is fine

Decoding URL query items for schemes where + is to be treated as a space

	NSURLComponents *components = [NSURLComponents componentsWithString:input];

	// Re-encode + symbols so NSURLQueryItem recognises them as spaces
	components.percentEncodedQuery = [components.percentEncodedQuery
	stringByReplacingOccurrencesOfString:@"+"
	withString:@"%20"];

	NSArray *items = components.queryItems;
	// Enumerate and handle the items
