ios-Monitor keyboard input, view move up or restore overall-avoid input occlusion

1. Initialize input box, listen input box start Edit and End edit

//Password entry boxUitextfield *logininputpasswordstr = [Uitextfield inputtextwithimage:[UIImageimagenamed:@"Password"] Placeholdertext:nslocalizedstring (@"Password",Nil)]; Logininputpasswordstr. Frame= Rectmakewithpercent ( -/375.0,385/667.0,327/375.0, -/667.0);//Set Keyboard typeLogininputpasswordstr. Keyboardtype= Uikeyboardtypedefault;//Set Dark text[Logininputpasswordstr setsecuretextentry:YES];//Listen password input box text start input[Logininputpasswordstr AddTarget: SelfAction@selector(Logininputpasswordstrinputbegin) Forcontrolevents:uicontroleventeditingdidbegin];//Listen password input box text end input[Logininputpasswordstr AddTarget: SelfAction@selector(Logininputpasswordstrinputend) forcontrolevents:uicontroleventeditingdidend]; [ Self. ViewADDSUBVIEW:LOGININPUTPASSWORDSTR];

2. When you start editing, the view moves up, and the initial position is restored when you finish editing or tapping the screen.

//loginInputPasswordStr监听方法-(void)loginInputPasswordStrInputBegin{    [self moveView];}-(void)loginInputPasswordStrInputEnd{    [self resumeView];}// 点击屏幕取消输入,恢复视图初始位置-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{    [self.view endEditing:YES];    [self resumeView];}

3. Body Method!
