如何将ios sdk中的svg图像设置为按钮图像？

Question

我想在ipad.so中设置svg（可缩放矢量图形）图像作为按钮图像，以便我可以对ipad2使用相同的图像，ipad3

Answer 1

您必须使用third party库。 Quartz不知道SVG。

Answer 2

您还可以使用https://github.com/arielelkin/PocketSVG

//Step 1 
CGPathRef myPath = [PocketSVG pathFromSVGFileNamed:@"icon_convidar"]; 

//Step 2: To display it on screen, you can create a CAShapeLayer 
//and set myPath as its path property: 
CAShapeLayer *shape = [CAShapeLayer layer]; 
shape.path = myPath; 


//Step 3: Fiddle with it using CAShapeLayer's properties: 
shape.strokeColor = [UIColor redColor].CGColor; 
shape.lineWidth = 4; 

//Step 4: Display it! 
[self.btnConvidar.layer addSublayer:shape];
