//添加陰影 UIimageView *imageView = [[UIImageView alloc ] init]; imageView.layer.shadowColor = [UIColor blackColor].CGColor; imageView.layer.shadowOffset = CGSizeMake(3,2); imageView.layer.shadowOpacity = 0.6; imageView.layer.shadowRadius = 1.0; imageView.clipsToBounds = NO; //文字描邊 只設置shadowColor,不設置shadowOffset就能夠實現描邊效果
