Answer 1

There's no stringTag property on UIView. If you need to do this kind of thing you can use a category on UIView and store the tag in an associated object:

@interface UIView (StringTagAdditions)
@property (nonatomic, copy) NSString *stringTag;
@end

@implementation UIView (StringTagAdditions)
static NSString *kStringTagKey = @"StringTagKey";
- (NSString *)stringTag
{
    return objc_getAssociatedObject(self, kStringTagKey);
}
- (void)setStringTag:(NSString *)stringTag
{
    objc_setAssociatedObject(self, kStringTagKey, stringTag, OBJC_ASSOCIATION_COPY_NONATOMIC);
}
@end
