iPhone MapKit Framework to cache Google map for offline: Good Idea

1) Can MapKit Framework support caching Google Map on iPhone locally ? 
2) Can MapKit Framework support to use offline map during GPS-ing ?


Answer :
Unfortunately no, you cannot cache the google tiles (at least not in iOS 4.x). However, you can use an MKOverlay to create an overlay that displays and caches tiles from another map source like OpenStreetMap. Apple published an example TileMap overlay with their 2010 WWDC videos.


Reference link:
http://stackoverflow.com/questions/3792532/iphone-mapkit-framework-to-cache-google-map-for-offline-use


Q. I am working on GPS Track...but when my device is offline then not show the Map. Can you please help for shut out it ? or How to implement the tiles in my application ?
Answer preferred by Apple forum.
Answer 1. : As I understand it MapKit terms and conditions require Google, try route-me for an alternative framwork.


Answer 2. : MapKit maintains a fixed-size map tile cache that contains (roughly speaking) tiles for the most recently viewed areas.  If the device is offline, and your MKMapView is zoomed to an area for which there are no tiles in the tile cache, maps will not be available.

The only solution to this would be to bundle your own map tiles with your app and implement your own map view.  It's up to you to decide if that is worthwhile for your use case.

Time difference between two different times.

NSDate* secondDate = [dateFormatter dateFromString:endtime];

NSTimeInterval ti = [secondDate timeIntervalSinceDate:firstDate];

//NSString *str1 = [NSString stringWithFormat:@"%d",ti];

//NSLog(@"str1 %@",str1);

NSUInteger h, m, s;

h = (ti / 3600);

m = ((NSUInteger)(ti / 60)) % 60;

s = ((NSUInteger) ti) % 60;

NSString *str = [NSString stringWithFormat:@"%d:%02d:%02d", h, m, s];

//NSLog(@" strdiff : %@ ",str);

condition of allowed run the application in the both iPhone sdk etc.

NSFileManager to save an image to or load/remove an image from documents directory

Reference link :
http://www.friendlydeveloper.com/2010/02/using-nsfilemanager-to-save-an-image-to-or-loadremove-an-image-from-documents-directory-coding/
special thanks for "friendlydeveloper"

NSFileManager offers a convenient way to write images to and load them from the documents directory.

If you’re frequently doing that in your project, I suggest to wrap up NSFileManager support in three simple methods:

01	//saving an image

02

03	- (void)saveImage:(UIImage*)image:(NSString*)imageName {

04

05	NSData *imageData = UIImagePNGRepresentation(image); //convert image into .png format.

06

07	NSFileManager *fileManager = [NSFileManager defaultManager];

08

09	NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);

10

11	NSString *documentsDirectory = [paths objectAtIndex:0];

12

13	NSString *fullPath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:@"%@.png", imageName]];

14

15	[fileManager createFileAtPath:fullPath contents:imageData attributes:nil];

16

17	NSLog(@"image saved");

18

19

}

20

21	//removing an image

22

23	- (void)removeImage:(NSString*)fileName {

24

25	NSFileManager *fileManager = [NSFileManager defaultManager];

26

27	NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);

28

29	NSString *documentsDirectory = [paths objectAtIndex:0];

30

31	NSString *fullPath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:@"%@.png", fileName]];

32

33	[fileManager removeItemAtPath: fullPath error:NULL];

34

35	NSLog(@"image removed");

36

37

}

38

39	//loading an image

40

41	- (UIImage*)loadImage:(NSString*)imageName {

42

43	NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);

44

45	NSString *documentsDirectory = [paths objectAtIndex:0];

46

47	NSString *fullPath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:@"%@.png", imageName]];

48

49	return [UIImage imageWithContentsOfFile:fullPath];

50

51

}

Now, you can easily save an image like:

1	[self saveImage: myUIImage: @"myUIImageName"];

or load it like:

1	myUIImage = [self loadImage: @"myUIImageName"];

or remove it like:

1	[self removeImage: @"myUIImageName"];
