Question

Xcode complains about ” Expected expression required” for second else if statement in my code. Ive tried using parenthesis from code I had looked at on here but that didn’t work and not sure what expression it wants now? Works fine until I add a second else if
I realise this is probably basic objective C stuff but having never done an if statement for more then two items im a bit stuck

-(NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component
{


if ([text1 isFirstResponder])return arrStatus.count;

else


   if ([text2 isFirstResponder]);return arrStatus2.count;

   else ///<<<<< wants an expected expression here


       if ([text3 isFirstResponder]);return arrStatus2.count;

 }

Answer 1

You have spurious semi-colons after some of the if statements:

if ([text2 isFirstResponder]);   <--- here

Other than that your code is poorly indented and you should stop putting statements on the same line as the if/else if lines:

-(NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component
{
    if ([text1 isFirstResponder])
        return arrStatus.count;
    else if ([text2 isFirstResponder])
        return arrStatus2.count;
    else if ([text3 isFirstResponder])
        return arrStatus2.count;
 }
