Italic Font not work for Chinese/Japanese/Korean on iOS 7

Question

I want to set Italic Font Style in UITextView, but Italic Font just not work for Chinese/Japanese/Korean on iOS 7.Could anyone help?

Answer 1

Because there are no italic styled Chinese fonts on iOS, you need to use affine transformation to slant the normal styled Chinese font.

The code below gives a 15° slant to Heiti SC Medium:

CGAffineTransform matrix = CGAffineTransformMake(1, 0, tanf(15 * (CGFloat)M_PI / 180), 1, 0, 0);
UIFontDescriptor *desc = [UIFontDescriptor fontDescriptorWithName:@"Heiti SC Medium" matrix:matrix];
textView.font = [UIFont fontWithDescriptor:desc size:17];

Real effect:
