Calculate input from textfield in a loop - xcode

Question

How can I calculate a textfield in a loop? I have a textfield in a loop and I want to calculate the input in another textfield.
x = 36; y = 0; w = 36 h = 25 ;
moretext = 0 ;
for (moretext=0; moretext<5; moretext ++) {
textFiled1 = [[UITextField alloc]initWithFrame:CGRectMake(x, y, w, h)];
textFiled1.textAlignment = NSTextAlignmentCenter;
textFiled1.backgroundColor = [UIColor clearColor];
textFiled1.font = [UIFont fontWithName:#"Helvetica " size:(8)];
x+=36 ;
[self.view addSubview:textFiled1];
}
I want to have the TOTAL for the textfield1 loop input showing in textfield2
textFiled2 = [[UITextField alloc]initWithFrame:CGRectMake(180, 0, 36, 25)];
textFiled2.textAlignment = NSTextAlignmentCenter;
textFiled2.backgroundColor = [UIColor clearColor];
textFiled2.font = [UIFont fontWithName:#"Helvetica " size:(8)];
[self.view addSubview:textFiled2];

Answer 1

Implementing the UITextFieldDelegate protocol you can get updates from the UITextField as people type. textFieldDidEndEditing: will tell you when someone is done editing a textfield as well.
See: http://developer.apple.com/library/ios/#documentation/uikit/reference/UITextFieldDelegate_Protocol/UITextFieldDelegate/UITextFieldDelegate.html

May be you need to revise the code:
At the time of allocating multiple UITextField objects, you need to store these in some array like this.
myArray = [[NSMutableArray alloc]init];
UITextField *textFiled1;
int moretext = 0 ;
for (moretext=0; moretext<5; moretext ++, y=y+50) {
textFiled1 = [[UITextField alloc]initWithFrame:CGRectMake(x, y, w, h)];
textFiled1.textAlignment = NSTextAlignmentCenter;
textFiled1.backgroundColor = [UIColor blueColor];
textFiled1.font = [UIFont fontWithName:#"Helvetica " size:(8)];
textFiled1.text = [NSString stringWithFormat:#"%d",y];
//x+=36 ;
[myArray addObject:textFiled1];
[self.view addSubview:textFiled1];
NSLog(#"view Did Load called");
}
Later to do the total you need to traverse through array and extract the text field value and accumulate in some variable like this.
- (int) calc {
int total=0;
int counter;
for (counter=0; counter<5; counter ++) {
UITextField *field1 = [myArray objectAtIndex:counter];
total = total + [field1.text intValue];
NSLog(#"value: %d",[field1.text intValue]);
}
return total;
}
