objective-C：获取以编程方式创建的文本字段的单个字符串

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
}

- (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
