IOS keyboard hiding

Method 1: Add [self. textfiled resignfirstresponder] to the button clicking event.

Method 2:

In the XIB file, you can not add a view control on the view page. A simple method is to set the class of the view page to uicontrol (this class inherits from uiview)

 

. H file:

# Import <uikit/uikit. h> @ interface homeviewcontroller: uiviewcontroller @ property (retain, nonatomic) iboutlet uitextfield * namefield; @ property (retain, nonatomic) iboutlet uitextfield * passwordfield;-(ibaction) textfielddoneediting) sender;-(ibaction) backgroundtap :( ID) sender; @ end

. M file:

 

 

# Import "homeviewcontroller. H" @ interface homeviewcontroller () @ end @ implementation homeviewcontroller
