I don't understand the solution. Can you explain in more detail how to fix the Linking problem?

ya i dont understand either

scratches head huh?

I think you haven't solved symbolic link problem. Just copy all data into cache directory then use maps without connections.

Version 3 needs online to load maps? Not working offline anymore? I am using version 5 converted map.

I think a copy function may be helpful in order to copy a pre-loaded map to cache directory anytime. I've seen this function in former version and think it could work wiht OS 3.0.

I have made a patch for GMM framework so it doesn't delete your cache: http://code.google.com/p/oranav/wiki/iPhoneOS30MapCaches

I tried oranav's patch and it works perfectly. Now, anything you view over a connection gets permanently saved to the cache so that it can be viewed even when not connected. It lets you save all zoom levels (unlike GMDL). You can also load entire cities with OM, but the file size might get pretty large. OM can also save map routes! Still not able to search streets, but that's ok.

thanks oranav and masks!!

I tested the route feature in OM and it only lets you save one route at a time. It works the first time but when I tried to delete the route (.plist), it does not work. Is this a bug or am I doing something wrong?

"in the state of the network connection, iPhone will write into the cache; If it found that it is unable to write, Maps will automatically delete the readable file and re-establish a cache file" We've found a way to avoid it: if Library/Caches directory is set a read-only permissions, you can avoid map cache being deleted by Maps

I create a new Folder for example "b" in /private/var/mobile/Media/Maps, than copy an older version of "com.apple.Maps.plist" in that Folder, browse around with maps.app a little bit, enter the directory /private/var/mobile/Libary/Caches/MapTiles?, where the created MapTiles?.sqlitedb will be. After that I copy the MapTiles?.db into the Folder "b". Now Map.app will no longer delete the Cache when started. No Permission changing is needed. Links wont work, but you can use your Maps offline perfectly. I tried with v 3.0.

thanks armswith, your method worked. i tried oranav's gmm patching method but it makes maps crash after rebooting your phone.

Can we just change the file name when the map is switched in stead of copy the whole map? It is very slow when the map is copied,

oranav's method crashed my maps app but setting the mapTiles folder to not allow write access seemed to solve the overite problem. the only down side is that it can't add to the cache so unless you keep within your offline maps area it keeps needing to reload all other tiles. (hmm i really should expand my map size)

here is a quick way to do set the MapTiles?? folder to read only: if you do not have it already go grab mobile terminal from cydia

then use the following command from the "mobile" directory (its the default starting point for terminal so as long as you haven't cd any where you should be fine): no "?" on the end <-- google does that for some reason

chmod 555 Library/Caches/MapTiles?

and to set it back to default:

chmod 755 Library/Caches/MapTiles?

Works like a charm! great work all, thank you so much. this i very usefull for me, cuz im in the process of looking for a new place to live, and Google maps has no support locally (Israel ...). what i did: placed the large MapTiles?.sqlitedb file (Israel is 778MB) under the folder: /private/var/mobile/Libary/Caches than gave it write permissions - 0755.

thanks again!

I made a bash-script to switch between different maps. It's not the best implementation (it is quite slow because it copies the whole maps to link it). map.sh

#!/bin/bash
if [ $# -eq 1 ]
then
  FILE=$PWD"/"$1"MapTiles.sqlitedb"
  if [ ! -f $FILE ]
  then
    echo "File not found: "$FILE
    exit
  fi
  echo "Restoring permissions. (755)"
  chmod 755 /var/mobile/Library/Caches/MapTiles
  echo "Copying "$FILE
  cp $FILE /var/mobile/Library/Caches/MapTiles/
  echo "Setting permissions. (555)"
  chmod 555 /var/mobile/Library/Caches/MapTiles
  echo "Done."
else
  echo "Supply directory to use."
fi

Give the script execute-permissions with:

chmod +x map.sh

Usage:

./map.sh Relative/Path/To/Folder

Where Folder contains MapTiles?.sqlitedb

hey guys, i still can't figure out how to do this.

where do I dump my folders containing MapTiles?.sqlitedb and do I just chmod that folder?

many thanks

i can't download anymore with gmdl!!! It doesn't download or preview anything... is that normal? thanx

I cannot download map with GMDL too. Any solution?

Try this one

I am confused. Offline Maps 2.1.0.4 isn't working at all. There is only a link option, which of course does not work. It tells me there are no routes or bookmarks to import. What is wrong?

offlinemaps not working on os 3.1!!! some news?

is it possible to let it work on 3.1? i think the problem is that maps cache now is in a new folder different from 3.0

/private/var/mobile/Library/Caches/Maps/MapTiles? on3.1 /private/var/mobile/Library/Caches/MapTiles?/ on3.0

and another question is does maps enhancer work with this change? i didn't try

Just to let you know after upgrading to 3.1.2 (jb-ed), the '0755/0555' trick doesn't work any more.. I wrote several scripts which worked perfectly at 3.1, but now it sucks!! Map file reduced from 100M to 400k even if i chmod as before! Any new tweaks?

for 3.1 ln -s /private/var/mobile/Library/Caches/Maps/MapTiles? /private/var/mobile/Library/Caches/MapTiles?

and maps enchancer still works

How about 3.1.2? I think Maps.app changes some mechanisms in deleting caches in 3.1.2. i.e., more strict deletion.

Same problem...3.1.2 not working. Still writes the file on the old folder (/private/var/mobile/Library/Caches/MapTiles?)and nothing on the new one. Solutions needed...

easy! ssh to your iphone See here http://code.google.com/p/iphoneofflinemap/issues/detail?id=52#c3

QUOTE:

$ cd /private/var/mobile/Library/Caches $ ln -s Maps/MapTiles?/ MapTiles?

Then offline maps works again! Even for 3.1 firmware Cheers~
