Question

I have multiple textviews in my uiview I need to set the font size of this textviews, so I used the following code but it didn’t change the font size,

for (UIView *subview in self.view.subviews) {

    if ([subview isKindOfClass:[UITextView class]]) {

        ((UITextView *)subview).font = [UIFont fontWithName:@"Helvetica" size:12];
    }

}

As @jrturton says, perhaps your text views are subviews of a subview, then some kind of recursive code is needed. For example:

-(void) setNewFontToTextViews:(UIView*) theView {
    if([[theView subviews] count]) 
        for( UIView * subView in [theView subviews])
            [self setNewFontToTextViews:subView] ;
    else if([theView isKindOfClass:[UITextView class]])
        [(UITextView*)theView setFont:[UIFont fontWithName:@"Helvetica" size:12]];
}
