iPhone location button

Ya know the little location button in the lower-left corner of the Maps application? Does anybody know where I can find that? I looked in UIButtonType and UITabBarSystemItem but came up blank.

I'd prefer to use a system image or a system something-or-other, to help ensure consistency with other system functions.

You can try using MKUserTrackingBarButtonItem It provides the same functionality as the track button on the Map app. Here is some same code.

MKUserTrackingBarButtonItem *trackButton = [[MKUserTrackingBarButtonItem alloc] initWithMapView:self.mapView];
NSMutableArray *items = [[NSMutableArray alloc] initWithArray:self.bottomToolbar.items];
[items insertObject:trackButton atIndex:0];
[self.bottomToolbar setItems:items];

Have a look at https://github.com/myell0w/MTLocation

Idle Mode Searching Mode Receiving Location Updates Mode Receiving Heading Updates Mode

I mimiced Google Maps' Locate Me - Button, including 4 different states and the animation that is done when switching between states.

Please note that in 4.0, the appearance of the "locate me" button in Maps.app button has changed. Further on, +[UIimage kitImageNamed:] is gone, and calling -[UIBarbuttonItem initWithBarButtonSystemItem:] with undocumented identifier 100 will return old-style graphics.

UIImage* img = [UIImage kitImageNamed:@"UIButtonBarLocate.png"];
// Get the location of the Documents directory
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) ;
NSString *imagePath = [paths objectAtIndex:0] ;
NSString *filename = @"test.png" ; 
NSString *filepath = [NSString stringWithFormat:@"%@/%@", imagePath, filename] ;

// Save the image 
NSData *imageData = [NSData dataWithData:UIImagePNGRepresentation(img)];
[imageData writeToFile:filepath atomically:YES];

use this sample of code to save it as a file that you'll be able to use in your project!

Hope this help.

(Warning: undocumented feature, will be rejected by AppStore, blah blah blah)

The location button can be accessed with

UIBarButtonItem* item = [[UIBarButtonItem alloc]
                         initWithBarButtonSystemItem:100
                                              target:... action:...];

If you just want the image, save the result returned by

UIImage* img = [UIImage kitImageNamed:@"UIButtonBarLocate.png"];

I created my own image, and Apple accepted it (in contrast of using the search image for zooming purposes).

I wouldn't be so sure that it's a system image. Many images/buttons in Apple's applications are specific to that application only, and this one looks to be that way.
