为什么要使用FontAwesome呢,其实,它的字体就是矢量图,无论是放大还是缩小都不失真的矢量图哦.
1. 下载源码,导入文件夹FontAwesomeKit,然后引入头文件FontAwesomeKit.h
2. 使用
// 取得固定的icon以及设定尺寸 FAKZocial *twitterIcon = [FAKZocial stackoverflowIconWithSize:50]; // 设定相关的属性 [twitterIcon addAttribute:NSForegroundColorAttributeName value:[UIColor redColor]]; // 在UILabel上显示 UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 200, 200)]; label.attributedText = [twitterIcon attributedString]; [self.view addSubview:label]; label.center = self.view.center;
使用是非常简单的哦,效果如下:
3. 高级应用
你以为就显示出来就没了么?非也,你想过把字体转换为路径么,转换为路径后就可以执行各种CoreAnimation的动画了呢:)
先来试一下CAshapeLayer的动画路径:
// 取得固定的icon以及设定尺寸 FAKZocial *twitterIcon = [FAKZocial chromeIconWithSize:100]; // 设定相关的属性 [twitterIcon addAttribute:NSForegroundColorAttributeName value:[UIColor blackColor]]; // 将icon转换为贝塞尔曲线 UIBezierPath *path = [UIBezierPath pathFromAttributedString:[twitterIcon attributedString]]; // 创建shapeLayer CAShapeLayer *shapeLayer = [CAShapeLayer layer]; // 获取path shapeLayer.path = path.CGPath; // 根据这个path来设定尺寸 shapeLayer.bounds = CGPathGetBoundingBox(shapeLayer.path); // 几何反转 shapeLayer.geometryFlipped = YES; // 一些颜色的填充 shapeLayer.fillColor = [UIColor clearColor].CGColor; shapeLayer.strokeColor = [UIColor cyanColor].CGColor; // 设定layer位置 shapeLayer.position = self.view.center; [self.view.layer addSublayer:shapeLayer]; // 定时器动画 _timer = [[GCDTimer alloc] initInQueue:[GCDQueue mainQueue]]; [_timer event:^{ shapeLayer.strokeEnd = arc4random()%100/100.f; } timeInterval:NSEC_PER_SEC]; [_timer start];
