RMPickerViewController 
This framework allows you to pick something with a picker presented as an action sheet. In addition, it allows you to add actions arround the presented picker which behave like a button and can be tapped by the user. The result looks very much like an UIActionSheet or UIAlertController with a UIPickerView and some UIActions attached.
Besides being a fully-usable project, RMPickerViewController also is an example for an use case of RMActionController. You can use it to learn how to present a picker other than UIPickerView.

Demo Project
If you want to run the demo project do not forget to initialize submodules.
Installation (CocoaPods)
platform :ios, '8.0'
pod "RMPickerViewController", "~> 2.3.1"
Usage
For a detailed description on how to use RMPickerViewController take a look at the Wiki Pages. The following four steps are a very short intro:
- Import
RMPickerViewController:
#import <RMPickerViewController/RMPickerViewController.h>
- Create select and cancel actions:
RMAction<UIPickerView *> *selectAction = [RMAction<UIPickerView *> actionWithTitle:@"Select" style:RMActionStyleDone andHandler:^(RMActionController<UIPickerView *> *controller) {
NSMutableArray *selectedRows = [NSMutableArray array];
for(NSInteger i=0 ; i<[controller.contentView numberOfComponents] ; i++) {
[selectedRows addObject:@([controller.contentView selectedRowInComponent:i])];
}
NSLog(@"Successfully selected rows: %@", selectedRows);
}];
RMAction<UIPickerView *> *cancelAction = [RMAction<UIPickerView *> actionWithTitle:@"Cancel" style:RMActionStyleCancel andHandler:^(RMActionController<UIPickerView *> *controller) {
NSLog(@"Row selection was canceled");
}];
- Create and instance of
RMPickerViewControllerand present it:
RMPickerViewController *pickerController = [RMPickerViewController actionControllerWithStyle:style title:@"Test" message:@"This is a test message.\nPlease choose a row and press 'Select' or 'Cancel'." selectAction:selectAction andCancelAction:cancelAction];
pickerController.picker.dataSource = self;
pickerController.picker.delegate = self;
[self presentViewController:pickerController animated:YES completion:nil];
- The following code block shows you a complete method:
- (IBAction)openPickerController:(id)sender {
RMAction<UIPickerView *> *selectAction = [RMAction<UIPickerView *> actionWithTitle:@"Select" style:RMActionStyleDone andHandler:^(RMActionController<UIPickerView *> *controller) {
NSMutableArray *selectedRows = [NSMutableArray array];
for(NSInteger i=0 ; i<[controller.contentView numberOfComponents] ; i++) {
[selectedRows addObject:@([controller.contentView selectedRowInComponent:i])];
}
NSLog(@"Successfully selected rows: %@", selectedRows);
}];
RMAction<UIPickerView *> *cancelAction = [RMAction<UIPickerView *> actionWithTitle:@"Cancel" style:RMActionStyleCancel andHandler:^(RMActionController<UIPickerView *> *controller) {
NSLog(@"Row selection was canceled");
}];
RMPickerViewController *pickerController = [RMPickerViewController actionControllerWithStyle:style title:@"Test" message:@"This is a test message.\nPlease choose a row and press 'Select' or 'Cancel'." selectAction:selectAction andCancelAction:cancelAction];
pickerController.picker.dataSource = self;
pickerController.picker.delegate = self;
[self presentViewController:pickerController animated:YES completion:nil];
}
Migration
See Migration on how to migrate to the latest version of RMPickerViewController.
Documentation
There is an additional documentation available provided by the CocoaPods team. Take a look at cocoadocs.org.
Requirements
| Compile Time | Runtime |
|---|---|
| Xcode 7 | iOS 8 |
| iOS 9 SDK | |
| ARC |
Note: ARC can be turned on and off on a per file basis.
Version 1.4.0 and above of RMPickerViewController use custom transitions for presenting the picker view controller. Custom transitions are a new feature introduced by Apple in iOS 7. Unfortunately, custom transitions are totally broken in landscape mode on iOS 7. This issue has been fixed with iOS 8. So if your application supports landscape mode (even on iPad), version 1.4.0 and above of this control require iOS 8. Otherwise, iOS 7 should be fine. In particular, iOS 7 is fine for version 1.3.3 and below.
Further Info
If you want to show an UIDatePicker instead of an UIPickerView, you may take a look at my other control called RMDateSelectionViewController.
If you want to show any other control you may want to take a look at RMActionController.
