We at make sure that your child gets the perfect learning environment to outperform.

Step 1 : Open the XCode and create a new Single View Based Application template. Give the application name "Multiple Button in AlertView Example". Copy this Code to the ViewController.h

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController <UIPickerViewDelegate, UIPickerViewDataSource>

@property (weak, nonatomic) IBOutlet UIPickerView *pickerviewControl;
@property (weak, nonatomic) IBOutlet UILabel *lblItem;
@property (nonatomic,retain) NSArray *countries;


Step 2 : Copy the Following Code into your ViewController.m File.

#import "ViewController.h"

@implementation ViewController

@synthesize pickerviewControl;
@synthesize lblItem;
@synthesize countries;

- (void)viewDidLoad
    countries = [[NSArray alloc]initWithObjects:@"India",@"Australia",@"USA", @"Canada", @"Srilanka",@"England",@"UK", nil];
	[super viewDidLoad];
	//Do any additional setup after loading the view, typically from a nib.

// returns the number of 'columns' to display.

- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView
    return 1;

// returns the # of rows in each component..

- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent: (NSInteger)component
    return [countries count];

//Delegate Method

- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component
    return [countries objectAtIndex:row];

- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component
    [lblItem setText:[NSString stringWithFormat:@"Selected Country : %@",[countries objectAtIndex:row]]];
