I m writing a game write now which involves saving highscores and basic data such as "soundeffects on" and "music on" onto a plist file. However, when in the future, I need to update my game and upload a new version of the app onto users iphones/ipods, how will the highscores be retained? Is there a way to save specific plist files while overwriting others? Thanks in advance!
EDIT: Is there any way to overwrite PART of a plist or merge an existing plist with a new one?
如果您在文档目录中重新放入这些列表, 您无需做任何进一步的工作。 当您的应用程序升级时, 这些文件都会被保留 。 您可以得到这样的文档目录 :
+ (NSString*) documentsPath
{
NSArray* sysPaths = NSSearchPathForDirectoriesInDomains( NSDocumentDirectory, NSUserDomainMask, YES );
return [sysPaths objectAtIndex:0];
}
