passing NSString from one class to the other

Question

I have a NSString that is taken from a UITextField in a ViewController. Every of my other ViewController will use this NSString as well. How can I pass this NSString to othe

Answer 1

Create a class for sharing your common objects. Retrieve it using a static method, then read and write to its properties.

@interface Store : NSObject {
    NSString* myString;
}

@property (nonatomic, retain) NSString* myString;

+ (Store *) sharedStore;

@end

and

@implementation Store

@synthesize myString;    

static Store *sharedStore = nil;

// Store* myStore = [Store sharedStore];
+ (Store *) sharedStore {
    @synchronized(self){
        if (sharedStore == nil){
            sharedStore = [[self alloc] init];
        }
    }

    return sharedStore;
}

// your init method if you need one

@end

in other words, write:

Store* myStore = [Store sharedStore];
myStore.myString = @"myValue";

and read (in another view controller):

Store* myStore = [Store sharedStore];
myTextField.text = myStore.myString;
