How To Get Selected Value From UIPickerView

Question

You can get it in the following manner:

NSInteger row;
NSArray *repeatPickerData;
UIPickerView *repeatPickerView;

row = [repeatPickerView selectedRowInComponent:0];
self.strPrintRepeat = [repeatPickerData objectAtIndex:row];

You can get the text of the selected item in any section of the picker using the same function that the pickerView does, from your custom ViewController class:

-(NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component

using the selected item

[myPickerView selectedRowInComponent:0]

so to set the text of a label in a custom cell using the currently selected value from the 2nd section of myPickerView (a property of your view controller probably)

[cell.label setText:[self pickerView:myPickerView titleForRow:[myPickerView selectedRowInComponent:1] forComponent:1]];

Just change both :1s to :2s, etc for each section

This is what I did:

- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component {

    selectedEntry = [allEntries objectAtIndex:row];

}

The selectedEntry is a NSString and will hold the currently selected entry in the pickerview. I am new to objective C but I think this is much easier.

You can access the selected row for a given component using the following method:

- (NSInteger)selectedRowInComponent:(NSInteger)component

Otherwise, implementing the delegate function is the only other option.

You will need to ask the picker's delegate, in the same way your application does. Here is how I do it from within my UIPickerViewDelegate:

func selectedRowValue(picker : UIPickerView, ic : Int) -> String {

    //Row Index
    let ir  = picker.selectedRow(inComponent: ic);

    //Value
    let val = self.pickerView(picker,
                              titleForRow:  ir,
                              forComponent: ic);
    return val!;
}
