iOS Code Snippet Input-Dialog

Hi,

I extended the code of Erel and turned into a proper input-dialog.

Insert the code into a code-module.

#Region Input-Dialog with Objective C code
#If OBJC
- (void)ShowInputDialog:(NSString*)Input :(NSString*)Title :(NSString*)Message :(NSString*)OK :(NSString*)Cancel :(int)KeybardType
{
  UIAlertView * alert = [[UIAlertView alloc] initWithTitle:Title
    message:Message delegate:self cancelButtonTitle:Cancel otherButtonTitles:OK, nil];
    alert.alertViewStyle = UIAlertViewStylePlainTextInput;

    UITextField * alertTextField = [alert textFieldAtIndex:0];
    alertTextField.keyboardType = KeybardType;
   
    alertTextField.text = Input;
    alert.delegate = self;
    [alert show];
}
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
    if (buttonIndex == 1) {
        [self.bi raiseEvent:nil event:@"inputdialog_result:" params:@[[[alertView textFieldAtIndex:0] text]]];
    }
}
#End If

' InputType:
' 0 = UIKeyboardTypeDefault
' 1 = UIKeyboardTypeASCIICapable
' 2 = UIKeyboardTypeNumbersAndPunctuation
' 3 = UIKeyboardTypeURL
' 4 = UIKeyboardTypeNumberPad
' 5 = UIKeyboardTypePhonePad
' 6 = UIKeyboardTypeNamePhonePad
' 7 = UIKeyboardTypeEmailAddress
' 8 = UIKeyboardTypeDecimalPad
' 9 = UIKeyboardTypeTwitter
'10 = UIKeyboardTypeWebSearch
'11 = UIKeyboardTypeAlphabet
'12 = UIKeyboardTypeASCIICapable
Sub InputDialog(Input As String, Title As String, Message As String, Positive As String, Cancel As String, InputType As Int)
    Dim no As NativeObject = Me
    no.RunMethod("ShowInputDialog::::::", Array(Input, Title, Message, Positive, Cancel, InputType))
End Sub

Sub InputDialog_Result(Text As String)
    Log("Result: " & Text)
    Select strInputDialog
        Case "1"
            txtUserName.text=Text
        Case "2"
            ...
    End Select
End Sub
#End Region

Usage:

Sub Process_Globals
  Dim strUserName As String
  Dim strInputDialog As String
  Dim txtUserName As TextField
End Sub

Private Sub Application_Start (Nav As NavigationController)
...
...
    strInputDialog = "1"
    InputDialog(strUserName, "Username", "Please enter a name", "OK", "Cancel", 0)
End Sub

I do not know, but maybe you can help Erel.

 

[Erel]

It is not possible to change the font size.

You can always implement your own custom dialog with a simple panel.

What about multiple inputs @Filippo :3

Also, why don't you wrap this to a B4i library?

For getting button event, replace this method in above sample

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
    NSString *inStr = [NSString stringWithFormat: @"%ld", (long)buttonIndex];
    [self.bi raiseEvent:nil event:@"inputdialog_result::" params:@[([[alertView textFieldAtIndex:0] text]),(inStr)]];
}
