Question

I am trying to access the nsstring data out side the function and also outside the class.

How can I access useridStr outside the function and class? This is my code:

-(id)connectionDidFinishLoading:(NSURLConnection *)connection
{
    NSString *loginStatus = [[NSString alloc] initWithBytes:[webData mutableBytes]
        length:[webData length] encoding:NSUTF8StringEncoding];
    NSDictionary *loginDict = [[loginStatus JSONValue] objectForKey:@"UserDetails"];
    NSArray *userId = [loginDict valueForKey: @"userid"];
    NSString *useridStr = [userId lastObject];
    NSLog(@"--------------....%@", useridStr);
}

Answer 1

NSUserDefaults *pre = [NSUserDefaults standardUserDefaults];
[pre setObject:useridStr forKey:@"useridStr"];

where you want to need string:

NSUserDefaults *pre =[NSUserDefaults standardUserDefaults];
NSString * useridStr =[pre stringForKey:@"useridStr"];

OR

In .h file of anotherView

-(id)initUserInfo:(NSString *)string;

In .m file of anotherView

-(id)initUserInfo:(NSString *)string{   
if (self = [super initWithNibName:@"nextView" bundle:nil]) {

    useridStr=string
}
return self;
}

In .m File of firstView

-(IBAction)btnNext_TouchUpInside:(id)sender{
nextView *second =[[nextView alloc]initUserInfo:useridStr];
[self presentModalViewController:second animated:NO];
}
