Assign the value from a text field into an int variable to do some math with other variables and then return it?

Question

The code showing here assigns the value of an variables to the text field I want to do the opposite of that. _Initial.text = [NSString stringWithFormat:@"%f", init];

The opposite of the code above. Please help

Answer 1

The opposite of that would be getting converting string to float. You can do it with this

init = [_Initial.text floatValue];

Answer 2

You should search for an answer before you ask a question.

NSString *intString = @"123";
NSString *floatString = @"456.789";
int intVal = [intString intValue];
float floatVal = [floatString floatValue];
printf("%i %f\n",intVal,floatVal);
