SWIFT： 高阶函数reduce

高阶函数reduce优化代码，减少代码量。

func getTotalStateFromTestcase() -> Bool {
        var iTotalState:Bool = true
        for row in ATLDeviceManager.device.tableData!.displayArrayArray {
            if row.first == "Fail" {
                iTotalState = false
            }
        }
        return iTotalState
        //return ATLDeviceManager.device.tableData!.displayArrayArray.reduce(true, {$0 && ($1.first! != "Fail")})
    }
