Question

I got a string as mild,medium,hot.I split the string with comma as separator.I need to print it in a pickerView too.
I used the following code and got List count as 3 successfully.

    NSString *spList=[mdict objectForKey:@"spicinesstype"];
    NSArray *list = [spList componentsSeparatedByString:@","];
    NSLog(@"List count:%d",[list count]);
    return [list count];

But how could I display all 3 items in pickerview

Answer 1

You should set your class as the delegate of the picker view, Then implement these 3 delegate methods for your picker

- (NSInteger)pickerView:(UIPickerView *)thePickerView numberOfRowsInComponent:(NSInteger)component {
    return [array count];
}

- (NSString *)pickerView:(UIPickerView *)thePickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component {
    return [array objectAtIndex:row];
}

- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)thePickerView {
    return 1;
}
