IOS: Click button to die

Scene:
There is a button in the TableView cell, I need to click on this button and then make a view on its view controller change frame, but I click this button, cause the card to die, do not crash, all events expire, I initially thought the thread was stuck, or the event was passed to the view where I needed to change the frame, and I couldn't distribute the event.

Solution:
1. Use block resolution, or other design mode to pass the click message;
2. Use multithreading to solve, the most efficient and fast;


Example:
I'm using block resolution:

declare block in TableView
because I need to pass the value, so with parameters

typedef void (^btnblock) (modeldiscussionlist *);

  @property (nonatomic,copy)   btnblock            block;

In the protocol method for building cell TableView, I add a button click event here and set the button's tag value based on Indexpath.row to get the data

Implement block, and implement value-(void) Outlaftview: (UIButton *) button{    modeldiscussionlist *model = _dataarray[button.tag];    _block (model);}

Call Block when the view controller initializes the TableView

Call block    _commentstutableview.block = ^ (modeldiscussionlist *model)    {        //implement a method to change the view frame in the inside    };

That's how I solve this problem.
