Add the following to the viewcontroller. h file:Code

 
// Add the interface to discard the keyboard event-(ibaction) textfiledoneediting :( ID) sender;
 

Add the following code to the viewcontroller. M file:

// Touch the background to disable the keyboard implementation-(ibaction) backgroundtap :( ID) sender {// The variable should discard the keyboard at this time, when binding, note that it is associated with the view of the Background [textfield resignfirstresponder];}
