Popup/modal picker for a text field in iOS 7

I think the "standard" way, is to set the picker as the inputView of the text field.

UIPickerView *picker = [[UIPickerView alloc] init];self.textField.inputView = picker;

It will pop up front the bottom, just like the keyboard does when you touch in the text field.

Here's a simple implementation of how to use a picker as an input view:

@interface ViewController ()@property (weak, nonatomic) IBOutlet UITextField *tf;@property (strong,nonatomic) NSArray *theData;@end@implementation ViewController- (void)viewDidLoad {    [super viewDidLoad];    UIPickerView *picker = [[UIPickerView alloc] init];    picker.dataSource = self;    picker.delegate = self;    self.tf.inputView = picker;    self.theData = @[@"one",@"two",@"three",@"four"];}-(NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component {    return self.theData.count;}-(NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView {    return  1;}-(NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component {    return self.theData[row];}-(void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component {    self.tf.text = self.theData[row];    [self.tf resignFirstResponder];}

The ActionSheetPicker-3.0 library seems to do this pretty well.
