Question

i’m creating a bunch of textfields. i am stacking them vertical, so i use:

CGRectMake(193, ((i * 45) + 45), 240, 30)

then after each textbox is created, i increment i.

int i = 0

CGRect myRect = CGRectMake(193, ((i * 45) + 45), 240, 30)
UITextField *myTextField01 = [[UITextField alloc] initWithFrame:myRect];
//format and add to view text field
i++;

//create next text field
myRect = CGRectMake(193, ((i * 45) + 45), 240, 30) //can i get rid of this line?

UITextField *myTextField01 = [[UITextField alloc] initWithFrame:myRect];
//format and add to view text field
i++;

i need to reassign the myRect to get i updated to the value of 1.

is there a better way to do this so i don’t need to reassign myRect to get the update value of i?

Answer 1

CGRect is a struct, so you can increment the internal fields directly:

CGRect myRect = CGRectMake(193, 45, 240, 30);
UITextField *myTextField01 = [[UITextField alloc] initWithFrame:myRect];

myRect.origin.y += 45;
UITextField *myTextField02 = [[UITextField alloc] initWithFrame:myRect];

myRect.origin.y += 45;
UITextField *myTextField03 = [[UITextField alloc] initWithFrame:myRect];

I would also use a loop and some kind of container (probably NSArray), but that’s a side topic ;)
