Best way to save data?

[W1tchcr4ft]

hey guys, my app i´m coding on right now needs to save one String.
So I was wondering, if its better to write it in a .plis or save it in a file?
I failed on both ways...

You should use a plist for a single string. Also learn to search on the Apple's Developer's Resources.

for just one string, i would use NSUserDefaults, its a framework layed on top of plists. saving your string would be like this -

[[NSUserDefaults standardUserDefaults] setObject:myString forKey:@"MyStringKey"];

Loading…

wow, thanx, but does that realy work without declaring anything before?
or do i just have to declare one String from what the MyStringKey will be taken?

You don't need to declare anything. You can just retrieve your string with:

NSString* mySavedString = [[NSUserDefaults standardUserDefaults] stringForKey:@"MyStringKey"]

If I want to save several strings(uitextfields) and states of segmentedcontrolers. Just a simple "save" button, and then a "load" button. How do I do that?

EDIT:
save:

 NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
	[defaults setObject:[NSNumber numberWithInt:[feedProvider selectedSegmentIndex]] forKey:@"feedProvider"];
	[defaults synchronize];

load:

NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
feedProvider.selectedSegmentIndex = [[defaults objectForKey:@"feedProvider"] intValue];

Easy way to do it with several segmentedControlers?

Edit2:
When trying to save text:

myString = [[NSString alloc] intWithFormat:textfield.text];
[textfield setText:myString];
NSUserDefaults *stringDefault = [NSUserDefaults standardUserDefaults];
[stringDefault setObject:myString forKey:@"stringKey"];

- this works but gives warning.
initWithString changed to stringWithString - no warning but app crarshes. Why?
