Click on UITextField to show a UIPickerView

Some time it is required in iPhone to add UIPickerView in UIActionSheet. Here are the steps to do that

In ViewController.h

@interface ViewController : UIViewController<UIPickerViewDataSource, UIPickerViewDelegate, UITextFieldDelegate>

{

IBOutlet UITextField *txtText;

NSArray *arrState;

   UIPickerView *pktStatePicker ;

   UIToolbar *mypickerToolbar;

}

In ViewController.m

@implementation ViewController

- (void)viewDidLoad

{

[super viewDidLoad];

arrState= [NSArray    initWithObjects:@"NewYork",@"NewJercy",@"Carlifornia",@"Florida",@"Fremont",@"SantaClara",@"San Diego",@"San Fransisco",@"San Jose", nil];

pktStatePicker = [[UIPickerView alloc] initWithFrame:CGRectMake(0, 43, 320, 480)];

pktStatePicker.delegate = self;

pktStatePicker.dataSource = self;

[pktStatePicker  setShowsSelectionIndicator:YES];

txtText.inputView =  pktStatePicker  ;

// Create done button in UIPickerView

mypickerToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 56)];

mypickerToolbar.barStyle = UIBarStyleBlackOpaque;

[mypickerToolbar sizeToFit];

NSMutableArray *barItems = [[NSMutableArray alloc] init];

UIBarButtonItem *flexSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil];

[barItems addObject:flexSpace];

UIBarButtonItem *doneBtn = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:selfaction:@selector(pickerDoneClicked)];

[barItems addObject:doneBtn];

[mypickerToolbar setItems:barItems animated:YES];

txtText.inputAccessoryView = mypickerToolbar;

}

-(void)pickerDoneClicked

{

NSLog(@"Done Clicked");

[txtText resignFirstResponder];

  mypickerToolbar.hidden=YES;

  pktStatePicker.hidden=YES;

}

- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView

{

return 1;

}

- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component

{

return [arrState count];

}

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

{

return [arrState objectAtIndex:row];

}

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

{

txtText.text = [arrState objectAtIndex:row];

}
