iOS 7 Back Button Symbol?

Question

I really like the shape of the back button arrow in iOS 7, and would like to use it on one of my UIButtons, but like > instead of <. Would there be a way with text, or should

Answer 1

i meant to answer this question:

Creating a left-arrow button (like UINavigationBar's "back" style) on a UIToolbar

(inspired by machoota's answer there), but it's locked, and, being new, i don't have the rep ... anyway, swiftui version:

struct BackArrow: View
{
    @Environment(\.horizontalSizeClass) var hsc: UserInterfaceSizeClass?
    @Environment(\.verticalSizeClass) var vsc: UserInterfaceSizeClass?

    var color: Color

    var body: some View {

        Path { path in

            let height = self.arrowHeight(h: self.hsc, v: self.vsc)
            let width = height * 0.6

            path.move(to: CGPoint(x: width * 5.0 / 6.0, y: height * 0.0 / 10.0))
            path.addLine(to: CGPoint(x: width * 0.0 / 6.0, y: height * 5.0 / 10.0))
            path.addLine(to: CGPoint(x: width * 5.0 / 6.0, y: height * 10.0 / 10.0))

            path.addQuadCurve(  to:         CGPoint(    x: width * ((6.0 / 6.0) + self.fudgeFactor(h: self.hsc, v: self.vsc)),
                                                        y: height * ((9.0 / 10.0) - (self.fudgeFactor(h: self.hsc, v: self.vsc) * 1.666666))),
                                control:    CGPoint(    x: width * ((6.0 / 6.0) + self.fudgeFactor(h: self.hsc, v: self.vsc)),
                                                        y: height * 10.0 / 10.0))

            path.addLine(to: CGPoint(   x: width * ((2.0 / 6.0) + (3 * self.fudgeFactor(h: self.hsc, v: self.vsc))),
                                        y: height * 5.0 / 10.0))

            path.addLine(to: CGPoint(   x: width * ((6.0 / 6.0) + self.fudgeFactor(h: self.hsc, v: self.vsc)),
                                        y: height * ((1.0 / 10.0) + (self.fudgeFactor(h: self.hsc, v: self.vsc) * 1.666666))))

            path.addQuadCurve(  to:         CGPoint(    x: width * 5.0 / 6.0,
                                                        y: height * 0.0 / 10.0),
                                control:    CGPoint(    x: width * ((6.0 / 6.0) + self.fudgeFactor(h: self.hsc, v: self.vsc)),
                                                        y: height * 0.0 / 10.0))

        }
            .fill(color)
            .offset(x: -8.0, y: -5.0) // there's probaby some better way to figure this out, but i've wasted too much time already ...
    }

    private func fudgeFactor(h: UserInterfaceSizeClass?, v: UserInterfaceSizeClass?) -> CGFloat
    {   return h == .compact ? ( v == .compact  ? 0.01      // (c, c): normal phone, landscape
                                                : 0.003 )   // (c, r): any phone, portrait
                            : ( v == .compact   ? 0.01      // (r, c): large phone, landscape
                                                : 0.003 )   // (r, r): ipad, full-screen, any
    }

    private func arrowHeight(h: UserInterfaceSizeClass?, v: UserInterfaceSizeClass?) -> CGFloat
    {   return h == .compact ? ( v == .compact  ? 18.0      // (c, c): normal phone, landscape
                                                : 21.0  )   // (c, r): any phone, portrait
                            : ( v == .compact   ? 18.0      // (r, c): large phone, landscape
                                                : 21.0 )    // (r, r): ipad, full-screen, any
    }
}

it's a filthy hack, but then again, trying to do anything remotely custom in swiftui feels pretty hacky right now anyway ...
