Can someone help me save simple strings in Xcode? - ios

Question

I've been trying to save strings in Xcode such as email and password so i can open them in different view, So far every attempt for the past 2 weeks have failed.
does anyone have a working way, and if so can you post the code.
Thanks
*edit***
Almost done just having an error here
(MemberPage *)initWithString: (NSString) S {
self = [super init];
if ( self ) {
//DO STUFF;
UserNAME.text = S.text;
}
return self;
}
error is on the first line:
use of undeclared identifier with initWithString
Also get should be a ; before :

Answer 1

(MemberPage *)initWithString: (NSString *) s {
self = [super init];
if ( self ) {
//DO STUFF;
UserNAME = s;
}
return self;
}
Forgot the '*'?

Answer 2

One of the easiest way's I've done this in the past is just to pass them in when I create my View:
RecieverClass.m:
(RecieverClass*) initWithString: (NString) S {
self = [super init];
if ( self ) {
//DO STUFF;
myLocalString = S;
}
return self;
}
SenderClass (where you create your view)
RecieverClass *recieverClass= [[RecieverClass alloc] initWithString:sendString];
[[self navigationController] pushViewController:recieverClass animated:YES];
[recieverClass release];
You could pass them in as pointers or w/e really. Just depends what you're trying to do really.

Answer 3

I use a singleton class to share data between different views and for me it works. In the source viewController, I assign the value as a parameter to the "shared" class, and in the destination viewController I retrieve it.
Dunno if it's the "legal" way to do it, but it's simple and it works.

Check out this tutorial: http://www.bit-101.com/blog/?p=1969
At a certain point you arrive at this piece of code:
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
if (self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]) {
// Custom initialization
Model *model = [Model sharedModel];
[model addObserver:self forKeyPath:#"text" options:NSKeyValueObservingOptionNew context:nil];
}
return self;
}
Adding the observer didn't immediately work for me, dunno why but I didn't look into this issue deeper.
I changed it into:
Model *model = [Model sharedModel];
model.parameter = #"btnMainToTarget";
Follow the instruction from beginning till end - it will work.
To any other people; don't hesitate to react if you didn't think my reply was accurate.
