Due to the disappearence of @madjid, I've forked his repo so people can have a woring framework.

MMPickerView

An easy to use and customizable view component that presents a UIPickerView with a toolbar, Done button, animation, design options, selected value and previously selected value functionality. Works with iOS 6 and even better in iOS 7, because it let's you change the background color of the PickerView.

Images to the left: iOS 6. Images to the right: iOS 7.

## Installation

From CocoaPods

Add pod 'MMPickerView', '~> 0.0.1' to your Podfile.
Install by running pod install
Include MMPickerView by adding #import <MMPickerView.h>

Manually

Important note if your project doesn't use ARC: you must add the -fobjc-arc compiler flag to MMPickerView.m in Target Settings > Build Phases > Compile Sources.

Drag the MMPickerView/MMPickerView folder into your project.
Make sure you have the CoreGraphics framework in your project.
Include MMPickerView by adding #import "MMPickerView.h"

Usage

(see sample Xcode project in /Demo)

MMPickerView is created as a singleton (i.e. it doesn't need to be explicitly allocated and instantiated; you directly call [MMPickerView method]).

Showing the PickerView

You can show the PickerView:

+(void)showPickerViewInView: (UIView *)view
                withStrings: (NSArray *)strings
                withOptions: (NSDictionary *)options
                 completion: (void(^)(NSString *selectedString))completion;

+(void)showPickerViewInView: (UIView *)view
                withObjetcs: (NSArray *)objects
                withOptions: (NSDictionary *)options
    objectToStringConverter: (NSString *(^)(id object))converter
       			 completion: (void(^)(id selectedObject))completion;

Example 1 - Show with an array of strings.

  
  NSArray *strings = @[@"This", @"is", @"just", @"an array", @"of strings."];

  [MMPickerView showPickerViewInView:self.view
                         withStrings:strings
                         withOptions:nil
                          completion:^(NSString *selectedString) {
   							//selectedString is the return value which you can use as you wish
                            self.label.text = selectedString;
  }];

Example 2 - Show with an array of objects.

    
  NSArray *objects = @[@"This is a mix of objects", @14, @13.3, @"A string", @1000];

  [MMPickerView showPickerViewInView:self.view
   						 withObjects:objects
					     withOptions:nil
		    objectToStringConverter:^NSString *(id object) {
			//This is where you convert your object and return a string, for eg. return person.name;
	          return [object description];
   
              }
						 completion:^(id selectedObject) {
					     //The selected object is returned, and you can use the value as you wish
					     //For example: self.label.text = person.name;
					     self.label.text = [selectedObject description];
  }];

Customizing MMPickerView

Both show methods use a NSDictionary to set the options of the MMPickerView. If you want a native looking PickerView, just withOptions: nil. In case of customization, use any of the different properties to customize the PickerView. All of the properties are optional, which means that if you only want to change one thing, like for eg the text color you can do like this, withOptions: @{MMtextColor: [UIColor redColor]}

Options

MMbackgroundColor - UIColor
MMtextColor - UIColor
MMtoolbarBackgroundColor - UIColor
MMbuttonColor - UIColor
MMfont - UIFont
MMValueY - NSInteger
MMselectedObject - id
MMtoolbarBackgroundImage - UIImage
MMtextAlignment - NSNumber

  /*
  Options:
  MMbackgroundColor - UIColor - The background color of the PickerView (>=iOS 7)
  MMtextColor - UIColor - The text color of the PickerView
  MMtoolbarBackgroundColor - UIColor - The background color of the toolbar
  MMbuttonColor - UIColor - The background color (<= iOS 6) or text color (>=iOS 7) of the Done button
  MMfont - UIFont - The font of the PickerView labels
  MMValueY - NSInteger - The Y value from the top of every label in the PickerView, useful when changing font/font-size.
  MMselectedObject - id - The selected object presented in the PickerView, an object from the array, for eg. [yourArray objectAtIndex:0];
  MMtoolbarBackgroundImage - UIImage - The background image of the toolbar (320 x 44 for non retina, 640 x 88 for retina)
  MMtextAlignment - NSNumber - The text alignment of the labels in the PickerView, @0 for Left, @1 for Center, @2 for Right
 */

Example 3 - Show with an array of strings and with custom colors and custom font.

  
  NSArray *strings = @[@"This", @"is", @"just", @"an array", @"of strings."];
  UIFont *customFont  = [UIFont fontWithName:@"Palatino-Bold" size:19.0];
  NSDictionary *options = @{MMbackgroundColor: [UIColor blackColor],
                                  MMtextColor: [UIColor whiteColor],
                               MMtoolbarColor: [UIColor darkGrayColor],
                                MMbuttonColor: [UIColor whiteColor],
                                       MMfont: customFont,
                                     MMValueY: @5};

  
  [MMPickerView showPickerViewInView:self.view
                         withStrings:strings
                         withOptions:options
                          completion:^(NSString *selectedString) {
                            //selectedString is the return value which you can use as you wish
                            self.label.text = selectedString;
                          }];

Selected Value

A useful feature is to let the PickerView select whatever was selected last time. This can easily be done with both show methods, as shown in the Example 4.

Example 4 - Show with an array of strings set selectedValue on PickerView.

  
@interface ViewController ()

@property (nonatomic, strong) NSString * selectedString;

@end
  
  
@implementation ViewController

- (void)viewDidLoad
{
    [super viewDidLoad];
  
  self.selectedString = [_stringsArray objectAtIndex:0];
  
}


  
- (IBAction)showPickerViewButtonPressed:(id)sender {

  
  NSArray *strings = @[@"This", @"is", @"just", @"an array", @"of strings."];
  [MMPickerView showPickerViewInView:self.view
                         withStrings:strings
                         withOptions:@{selectedObject:_selectedString}
                          completion:^(NSString *selectedString) {
    
                            _label.text = selectedString;
                            _selectedString = selectedString;
  }];
  
}

@end
