For small apps you often need to store some basic settings, and using a plist file in the app’s document directory is an easy way to accomplish this. Below is a little snippet that I have used more than once for this purpose.
- (void)readAppSettings {
NSString *plistPath = [NSSearchPathForDirectoriesInDomains
(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
plistPath = [plistPath stringByAppendingPathComponent:@"ticjitsu-
settings.plist"];
NSFileManager *fileManager = [NSFileManager defaultManager];
if (![fileManager fileExistsAtPath:plistPath]) {
NSString *sourcePath = [[NSBundle mainBundle]
pathForResource:@"ticjitsu-settings" ofType:@"plist"];
[fileManager copyItemAtPath:sourcePath toPath:plistPath error:nil];
}
scoresDictionary = [NSMutableDictionary dictionaryWithContentsOfFile:
plistPath];
NSNumber *computerSkillNumber = scoresDictionary[@"settingComputerSkill"];
_computerSkill = [computerSkillNumber integerValue];
_gameWinsNone = scoresDictionary[@"gameWinsNone"];
}
- (void)saveAppSettings {
NSString *plistPath = [NSSearchPathForDirectoriesInDomains
(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
plistPath = [plistPath stringByAppendingPathComponent:@"ticjitsu-
settings.plist"];
NSNumber *computerSkillNumber = [NSNumber numberWithInt:_computerSkill];
[scoresDictionary setValue:computerSkillNumber
forKey:@"settingComputerSkill"];
[scoresDictionary setValue:_gameWinsNone forKey:@"gameWinsNone"];
[scoresDictionary writeToFile:plistPath atomically:YES];
}
