I am assuming an array, but it will work with dictionaries too.
Userdefaults, Core Data and Plists can all be read/write but if you use a plist you need to pay attention in what dir you put it. See the plist part down below.
Core Data I think it’s way too much overkill, it’s just strings.
It’s supposed to be used when you want to persist more complex objects.
NSUserDefaults:
It’s pretty fast and easy to do, though it’s supposed to store only user settings.
To write them to the userdefaults:
NSArray *stringsArray = [[NSArray alloc] arrayWithObjects: string1, string2, string3, nil];
[[NSUserDefaults standardUserDefaults] setObject:stringsArray forKey:@"MyStrings"];
[[NSUserDefaults standardUserDefaults] synchronize];
To read the from the userdefaults:
NSArray *stringsArray = [[NSUserDefaults standardUserDefaults] objectForKey:@"MyStrings"];
Plist:
If your strings are going to be modified you will need to write and read a plist but you cant’t write into your app’s resources.
-
To have a read/write plist first find the documents directory
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *stringsPlistPath = [[paths objectAtIndex:0] stringByAppendingPathComponent:@"Strings.plist"];
-
Create the array (I am assuming the strings are string1, …)
NSArray *stringsArray = [[NSArray alloc] arrayWithObjects: string1, string2, string3, nil];
-
Write it to file
[stringsArray writeToFile:stringsPlistPath atomically:YES];
To read the plist:
-
Find the documents directory
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *stringsPlistPath = [[paths objectAtIndex:0] stringByAppendingPathComponent:@"Strings.plist"];
-
Read it in:
NSArray *stringsArray = [NSArray arrayWithContentsOfFile:stringsPlistPath];
