Adding multiple text fields with the same code - ios

Question

I want to be able to add between 1 and 20 text fields to my view with the same code.
My idea is to use a for loop and every time add a text field so the first time it loops it adds "textField1" and the second time it adds "textField2" etc.
I'm not sure how I would go about coding this so I'm looking for your help.

Answer 1

Try this code
for 20 textfields you need to take them in UIScrollView .. you can do like this --
UIScrollView *scrollView = [[UIScrollView alloc]initWithFrame:CGRectMake(0,0,320,460)];
[scrollView setDelegate:self];
//initialize a textfield array;
NSMutableArray *textFieldArray = [[NSMutableArray alloc]init];
//x, y for first textfield in UIScrollView
float x = 20;
float y = 20;
For(int i=1;i<21;i++)
{
UITextfield *textField = [[UITextfield alloc]initWithFrame:CGRectMake(x,y,200,30)];
textfield.tag = i;
[textField setDelegate:self];
//Add Textfield to array just for futureRefrence
[textFieldArray addObject:textField];
//Add textfield in UIScrollView
[scrollView addSubview:textField];
//Now iterate Y , So they won't over each other
y = y+50;
}
//Now set ScrollView ContentSize
[scrollView setContentSize:CGSizeMake:(320,20*y)];
//Now Finally Add ScrollView in UIView
[self.view addSubView:scrollView];
Also remember declare there delegate in .h file .
and you can access these textfield by the array you put them in ,For Example
If you want a value from textfield three , you can do like this
UITextfield *textfield = (UITextfield *)[textFieldArray objectAtIndex:2];
NSLog(#"text of textField 3 is -- %#",textfield.text);

Answer 2

for (int i = 0; i < 20; i++)
{
UITextField *textField = //setup field
textField.tag = i;
[self.view addSubview:textField];
}
then when you want to reference a field later
UITextField *textField6 = [self.view viewWithTag:6];
UITextField *textField18 = [self.view viewWithTag:18];
etc

Answer 3

NSMutableArray* tfArray = [[NSMutableArray alloc]init];
for (int i = 0; i < 20; i++)
{
UITextField *textField = [[UITextField alloc]initWithFrame:CGRectMake(x, y, width, height)];
[self.view addSubview:textField];
[tfArray addObject:textField];
}
if you want to reference a field:
the 6th textfield is for example: (UITextField*)tfArray[5];
