objective-C : get individual strings for textfields created programmatically

Question

After going through the solution for this query, I get the output in the log when i print the mutableArray as shown below.

*Date Project name :* Save button : (
    Def
)

where 'Def' is the text entered in the textfield created dynamically. I want to extract 'Def'and display in log on save button click. Here's the code

- (IBAction)save:(id)sender {
    for(UITextField *field in self.scroll.subviews)
    {
        if([field isKindOfClass:[UITextField class]])
        {
            if([[field text] length] > 0)
            {
                NSMutableArray *mutableTextArray = [[NSMutableArray alloc] init];
                [mutableTextArray addObject:field.text];
                NSLog(@"Save button : %@", mutableTextArray);
                //NSString *str = [str stringByAppendingString:[mutableTextArray objectAtIndex:0]];
                //[self fetchStrings:str];
            }
        }
    }
}

- (void) fetchStrings:(NSString*)enteredString
{
    NSLog("%@", enteredString); //want 'def' to be displayed here
}

mutableTextArray should be instance level variable and not local. Then it will be accessible across instance methods. — Amar

- (IBAction)save:(id)sender {
    for(UIView *field in self.scroll.subviews)
    {
        if([field isKindOfClass:[UITextField class]])
        {
            if(((UITextField *)field).text.length > 0)
            {
                [mutableTextArray addObject:field.text];//mutableTextArray declare this locally in Interfacefile and then initialize the array in viewDidLoad

            }
        }
    }
    NSLog(@"%@", mutableTextArray); 
}

While you create UITextField set the Tag and use like this. I hope it will be work for you

i think u must have an array inside the innermost if condition. calling method directly is not working.

@DeepakThakur - (void) fetchStrings:(NSString*)enteredString; declare this in your interface file it will call this method

@DeepakThakur:Set break point inside this if(((UITextField *)field).text.length > 0) and check the condition satisfies or not?

it works after removing tag==100. Also, adding break will give me only the first textfields data. I need to handle the remaining ones also..

i need to change the parameter of fetchStrings from nsstring to nsarray to get all values
