Answer 1

I have 2 buttons - A- and A+

@interface NSUInteger textFontSize;  - (IBAction)changeTextFontSize:(id)sender {     switch ([sender tag]) {         case 1: // A-             textFontSize = (textFontSize > 50) ? textFontSize -5 : textFontSize;             break;         case 2: // A+             textFontSize = (textFontSize < 160) ? textFontSize +5 : textFontSize;             break;     }      NSString *jsString = [[NSString alloc] initWithFormat:@"document.getElementsByTagName('body')[0].style.webkitTextSizeAdjust= '%d%%'",                            textFontSize];     [web stringByEvaluatingJavaScriptFromString:jsString];     [jsString release]; }
