How to set a value to XLFormRowDescriptorTypeSelectorPush about xlform HOT 7 CLOSED

Do you mean the initially selected option? If so, you'll want something like this:

row.selectorOptions = @[
    [XLFormOptionsObject formOptionsObjectWithValue:@(1) displayText:@"Option 1"],
    [XLFormOptionsObject formOptionsObjectWithValue:@(2) displayText:@"Option 2"],
    [XLFormOptionsObject formOptionsObjectWithValue:@(3) displayText:@"Option 3"],
];
row.value = [XLFormOptionsObject formOptionsObjectWithValue:@(2) displayText:@"Option 2"];

Thanks for your reply.
Indeed I meant the initially selected option.
I save in my backend the selected XLFormOptions value (in this case '2'). I thought I just had to set row.value = 2 to have the XLFormOptionsObject displayed and selected.
Is this the case? Do I have to set the whole XLFormOptionsObject ([XLFormOptionsObject formOptionsObjectWithValue:@(2) displayText:@"Option 2"])?
Thanks

That's correct.

I guess you mean to set the whole whole XLFormOptionsObject.
It would be nice to have it as a dictionary: I give the key, it displays the text.
Thanks for this control.

You can avoid creating a new XLFormOptionsObject instance by selecting a value from the row.selectorOptions array. Like so:

NSPredicate *predicate = [NSPredicate predicateWithFormat:@"formValue == %@", @(3)];
row.value = [[row.selectorOptions filteredArrayUsingPredicate:predicate] objectAtIndex:0];

You can replace 3 with the form value of the object you want selected.

@batouri ,

You can get the reference to any XLFormOptionsObject using the convenient method +(XLFormOptionsObject *)formOptionsOptionForValue:(id)value fromOptions:(NSArray *)options;. Basically it does exactly the same @adamcooke suggests above.

Take a look at XLFormOptionsObject class definition...

@interface XLFormOptionsObject : NSObject <XLFormOptionObject>

+(XLFormOptionsObject *)formOptionsObjectWithValue:(id)value displayText:(NSString *)displayText;
+(XLFormOptionsObject *)formOptionsOptionForValue:(id)value fromOptions:(NSArray *)options;
+(XLFormOptionsObject *)formOptionsOptionForDisplayText:(NSString *)displayText fromOptions:(NSArray *)options;

@end

You can also take a look at https://github.com/xmartlabs/XLForm#selector-rows to see how to use another class as selector option. You can use some basic types, for example NSString, or any class that conforms to XLFormOptionObject protocol (XLFormOptionsObject conforms to it and it's just a convenience class).
