Question

for (Annotation *ann in annotaionArray) // annotationArray contains annotations added to map
{
    NSString *fetchedtitle = ann.title;

    if([fetchedtitle isEqualToString:oldTitle]); // oldTitle = textfield.text
    {
        ann.title = appDelegate.pinTitle;
        break;
    }
}

But the comparison is always true. What could be the error please?

fetched const char from sqlite is casted to stringWithUTF8String.

Everything has been done to cast perfectly to string but still why is the error in comparison?

Answer 1

Remove the trailing semi-colon!

if ([fetchedtitle isEqualToString:oldTitle])
{
    ann.title = appDelegate.pinTitle;
    break;
}

With the semi-colon, your code is the same as:

if ([fetchedtitle isEqualToString:oldTitle])
    ;
{
    ann.title = appDelegate.pinTitle;
    break;
}
