Answer 1

Is there a reason you can't store the information in the owning view controller? Is it for abstraction?

You can always extend UITapGestureRecognizer to carry more data:

@interface UserDataTapGestureRecognizer : UITapGestureRecognizer
@property (nonatomic, strong) id userData;
@end

@implementation UserDataTapGestureRecognizer
@end

...

UserDataTapGestureRecognizer *downloadOptionPressed =
    [[UserDataTapGestureRecognizer alloc] initWithTarget:self
    action:@selector(timeFrameLabelTapped:)];
downloadOptionPressed.userData = parameters;

...

- (void)downloadOptionPressed:(UserDataTapGestureRecognizer *)recognizer {
    NSArray *parameters = recognizer.userData;
}
