The drop down sometimes stop working...

[pulkitsinghal]

It took me a really long time but I finally figured out why sometimes QA and end users would say that the drop-down wasn't working for them in my app sporadically.

Short-story:
If a drop-down was not dismissed in one tab of the tab bar controller ... we just had enough time to see it scroll down before we quickly switch to the other tab of the tab bar controller. Now if you try to get a drop-down to show, it won't work.

I am not an expert in this YRDropdownView project's code but I think it has something to do with the fact that in the following method:

+ (YRDropdownView *)showDropdownInView:(UIView *)view 
                         title:(NSString *)title 
                        detail:(NSString *)detail 
                         image:(UIImage *)image
                      animated:(BOOL)animated
                     hideAfter:(float)hideAfter

the current dropdown still has a non-nil value and we add the rest of the dropdowns to the queue ... behind something that will never get cleared out.

if (currentDropdown) // add to queue - [email protected]

Here's the patch file that fixed the strange behavior.

My origin wasn't onemightyroar / YRDropdownView ... instead it was https://github.com/gregwym/YRDropdownView.git but the same patch should be still valid as a fix.

Hi @pulkitsinghal , sorry for the delay. I had a look into the issue and I don't see any reason for having the finished check.
I have applied your patch on gregwym@2e1955f

Thank you very much.
