POGetting a "NAN" error message within a UITextField
text
Body
copied!<p>I'm having major issues with an error message within a UITextField. I have a IBAction buttontap id sender setup to when I tap a UITextField and tap buttontap, it adds a value +1 to the UITextField that was selected. My issue is my UITextField that I have setup to come up with a percentage between two UITextfields is giving me a "NAN" error message when I tap other UITextFields. I thought I had this problem solved until I added more code. Here is my current code:</p> <pre><code>- (IBAction)buttonTap:(id)sender { int value = [currentText.text intValue] + 1; currentText.text = [NSString stringWithFormat:@"%d",value]; int n7 = [tex.text intValue]; int n8 = [tex2.text intValue]; int n9 = [tex3.text intValue]; int n10 = [tex4.text intValue]; int n11 = [tex5.text intValue]; int n12 = [tex6.text intValue]; int r = n7 + n8 + n9 + n10 + n11 + n12; NSString *rn = [NSString stringWithFormat:@"%d",r]; [tex13 setText:rn]; int n1 = [tex7.text intValue]; int n2 = [tex8.text intValue]; int n3 = [tex9.text intValue]; int n4 = [tex10.text intValue]; int n5 = [tex11.text intValue]; int n6 = [tex12.text intValue]; int s = n1 + n2 + n3 + n4 + n5 + n6; NSString *sn = [NSString stringWithFormat:@"%d",s]; [tex14 setText:sn]; float firstFloat = [self.tex15.text floatValue]; float secondFloat = [self.tex16.text floatValue]; float answer = secondFloat / firstFloat * 100; self.tex20.text = [NSString stringWithFormat:@"%.1f%%",answer]; } </code></pre>
