The way the IOS keyboard goes down

Let the keyboard down in general is the end of editing or let the keyboard lose the first response, I generally use these 3 methods:

First: Tap the screen to let the keyboard end the edit.

-(void) Touchesbegan: (Nsset *) touches withevent: (uievent *)event{    [Self.view endediting: YES];}

Second: Click outside the edit box to let the keyboard lose its first response:

-(void) touchesended: (Nsset *) touches withevent: (uievent *)event{    if (!  [TextField Isexclusivetouch])    {        [TextField resignfirstresponder];}    }

The third kind: Through the TextField proxy method, realizes

Uitextfielddelegate, the code is as follows:

-(BOOL) Textfieldshouldreturn: (Uitextfield *) _textfield{        [TextField resignfirstresponder];     return YES;    }
