Comparison of the use of Uialertcontrol with Uialertview and Uiactionsheet

1.UIAlertVIew in-(void) Show method displays:

-(void) viewdidload {    [super viewdidload];    Use of Uialertview    [self showalert];        Uiacyionsheet use//    [self showaction];    #pragma mark  [self showalertcontroller]; The method cannot be placed here because Uialertcontrol inherits from    the use of Uiviewcontroller//uialertcontrol    [self showalertcontroller];       }

Implementation of Uialertview:

-(void) showalert{    uialertview *alertview = [[Uialertview alloc]initwithtitle:@ "Emergency notice" message:@ "due to the happiness index Oh falling, After investigation and vacation into a linear relationship, special approval after work one day rest day "delegate:self cancelbuttontitle:@" Cancel "otherbuttontitles:@" OK ", nil];     Alertview.alertviewstyle =  Uialertviewstyledefault;    /*     Uialertviewstyledefault, default     uialertviewstylesecuretextinput, password input box     uialertviewstyleplaintextinput ,  text input box     uialertviewstyleloginandpasswordinput user and password     */        [Alertview show];} #pragma mark-uialertdelegate-(void) Alertview: (Uialertview *) Alertview Clickedbuttonatindex: (Nsinteger) ButtonIndex {    switch (buttonindex) {case        0:            NSLog (@ "Click%ld", Buttonindex);            break;            Case 1:            NSLog (@ "Click%ld", Buttonindex);            break;        Default: Break            ;    }}

Use of 2.UIActionSheet

-(void) showaction{    uiactionsheet *actionsheet = [[Uiactionsheet alloc]initwithtitle:@ ' leave \ Select leave type ' delegate:self cancelbuttontitle:@ "Cancel" destructivebuttontitle:@ "Leave" otherbuttontitles:@ "sick Leave" @ "maternity leave", nil];    [Actionsheet ShowInView:self.view];} -(void) didreceivememorywarning {    [super didreceivememorywarning];    Dispose of any resources the can be recreated.} #pragma mark uiactionsheetdelegate-(void) Actionsheet: (Uiactionsheet *) Actionsheet Clickedbuttonatindex: (NSInteger) buttonindex{    Switch (buttonindex) {case        0:            NSLog (@ "Click%ld", Buttonindex);            break;        Case 1:            NSLog (@ "Click%ld", Buttonindex);            break;        Case 2:            NSLog (@ "Click%ld", Buttonindex);            break;        Default: Break            ;    }}
