n.b. This repo is old and no longer maintained. I’m leaving it as-is in the hope that it may still be helpful or at the very least, a relic of the past.

MKMapView + UITableView + Parallax scrolling. Provides a framework for building an interactive location picker on iOS.

This view is useful for when a list of scrollable, selectable locations need to be shown along with their locations on map. A search bar can easily be added for searching or filtering.

Install

Cocoapods

pod 'LocationPickerView', '~> 1.2.0'

Manual

Drop the LocationPickerView folder into your app.

Usage

In the view controlller you’d like to use the location picker in, add the following lines to viewDidLoad:

LocationPickerView *locationPickerView = [[LocationPickerView alloc] initWithFrame:self.view.bounds];
locationPickerView.tableViewDataSource = self;
locationPickerView.tableViewDelegate = self;
[self.view addSubview:self.locationPickerView];

Alternatively, you can setup the LocationPickerView in a Storyboard. Just set the view’s class to LocationPickerView

and be sure to hook up the table view delegate and datasource.

Advanced Usage

If you want to get fancy you can specify more options:

// Create the location picker
LocationPickerView *locationPickerView = [[LocationPickerView alloc] initWithFrame:self.view.bounds];
locationPickerView.tableViewDataSource = self;
locationPickerView.tableViewDelegate = self;

// Optional parameters
locationPickerView.delegate = self;
locationPickerView.shouldCreateHideMapButton = YES;
locationPickerView.pullToExpandMapEnabled = YES;
locationPickerView.defaultMapHeight = 190.0;
locationPickerView.parallaxScrollFactor = 0.4; // little slower than normal.
locationPickerView.backgroundViewColor = [UIColor yellowColor]; //set color to the tableView background without the map

// Optional setup
self.locationPickerView.mapViewDidLoadBlock = ^(LocationPickerView *locationPicker) {
    locationPicker.mapView.mapType = MKMapTypeStandard;
};
self.locationPickerView.tableViewDidLoadBlock = ^(LocationPickerView *locationPicker) {
    locationPicker.tableView.separatorStyle = UITableViewCellSeparatorStyleSingleLine;
};

[self.view addSubview:self.locationPickerView];

Of particular use is the delegate property which allows you to know when important things are happening (like the map view is about to expand full screen).

NOTE: Don’t set the backgroundColor property of the table view. Color your cells or the LocationPickerView instead.

Feature Wishlist

  • Add map annotations that sync with table view.
  • Add some basic search functionality.
  • Add more map controls (zooming, following user location, etc).

Known Issues

  • Currently, deselecting a cell with animation doesn’t look so good. You’ll need to animate this yourself but hey, you can make it fancy!
