有没有人能够找到一种方法来解析Swift 3中的JSON文件?我已经能够返回数据但是在将数据分解为特定字段时我没有成功.我会发布示例代码,但我已经通过这么多不同的方法失败了,并没有保存任何.我要解析的基本格式是这样的.提前致谢.
{
"Language": {
"Field":[
{
"Number":"976",
"Name":"Test"
},
{
"Number":"977",
"Name":"Test"
}
]
}
}
Run Code Online (Sandbox Code Playgroud) 如何制作一条末端为圆形的线?我正在画一条简单的直线,如下所示,但不能把两端弄圆。“.cornerRadius”不起作用。有任何想法吗?
struct Line: View {
let geoProx: GeometryProxy
var body: some View {
Path{ path in
path.move(to: CGPoint(x: geoProx.size.width/2, y: geoProx.size.height/2))
path.addLine(to: CGPoint(x: geoProx.size.width/2 - geoProx.size.width/4, y: geoProx.size.height/2))
}
.stroke(lineWidth: 8.0)
.foregroundColor(.white)
.cornerRadius(10.0)
.zIndex(1.5)
}
}

func indicate() {

var small = selectedNode.position.x - ((CGFloat(smallest)*54) - 29)
indicatorRight.position = CGPointMake(selectedNode.position.x + large, selectedNode.position.y)
indicatorRight.userInteractionEnabled = true
indicatorRight.zPosition = 0.5
indicatorLeft.position = CGPointMake(selectedNode.position.x - small, selectedNode.position.y)
indicatorLeft.userInteractionEnabled = true
indicatorLeft.zPosition = 0.5
println(indicatorLeft.position)
// println(smallest)
self.addChild(indicatorRight)
self.addChild(indicatorLeft)
}
