swift中数据之间的转换

1.swift 开发 - NSDictionary与NSData互转、Dictionary与Data互转

https://blog.csdn.net/SuperMageHuang/article/details/54963236

1、NSDictionary转NSData
let data:NSData =NSKeyedArchiver.archivedData(withRootObject:dataDic) asNSData

2、NSData转NSDictionary
let dic =NSKeyedUnarchiver.unarchiveObject(with: dataas! Data)as! NSDictionary

3、NSDictionary转Data
let date =try! JSONSerialization.data(withJSONObject: dic, options: .prettyPrinted)

4、Data转Dictionary
let json =try! JSONSerialization.jsonObject(with: data, options: .mutableContainers)as! Dictionary<String,String>

2.(UITextField.text as NSSTring).floatValue

使用一个label 显示多行

private func setData(showStr: String) {

DispatchQueue.main.async {

self.leftTipLabel!.text = NSLocalizedString("可用", comment: "")+"\n\n"+NSLocalizedString("最小转帐量", comment: "")+"\n\n"+NSLocalizedString("手续费", comment: "")+"\n\n"+NSLocalizedString("到账数量", comment: "")

}

self.leftTipLabel?.numberOfLines = 0

let attributedStrM : NSMutableAttributedString = NSMutableAttributedString()

attributedStrM.append(NSAttributedString(string: available, attributes: [NSAttributedString.Key.foregroundColor: UIColor.hexadecimalColor(hexadecimal: "#F1B11B")]))

attributedStrM.append(NSAttributedString(string: " \(dataDict["currency"].stringValue.uppercased())"+"\n\n", attributes: [NSAttributedString.Key.foregroundColor: ThemeColor.sharedInstance.getTextColor()]))

attributedStrM.append(NSAttributedString(string: String(format: "%.3f", ((self.minWithdrawQuantity as String) as NSString).doubleValue), attributes: [NSAttributedString.Key.foregroundColor: UIColor.hexadecimalColor(hexadecimal: "#F1B11B")]))

attributedStrM.append(NSAttributedString(string: NSLocalizedString("个",  comment: "")+"\n\n", attributes: [NSAttributedString.Key.foregroundColor:ThemeColor.sharedInstance.getGrayTextWhiteColor()]))

var all:Double = 0

var totalFees:Double = 0

if self.moneyTextField?.text?.count == 0 {

all = 0

totalFees = 0

}else if (self.moneyTextField!.text! as NSString).doubleValue < (self.minWithdrawQuantity as NSString).doubleValue{

all = 0

totalFees = 0

}else{

let inputf:Double = Double((showStr as NSString).doubleValue)

let feesp:Double = Double((self.feeS as NSString).doubleValue) * inputf

if feesp > Double((self.firstFee as NSString).doubleValue) {

totalFees = Double((self.firstFee as NSString).doubleValue)

all = (showStr as NSString).doubleValue - totalFees

}else{

totalFees = feesp

all = Double((showStr as NSString).doubleValue) - totalFees

}

}

//手续费  "\(totalFees)"

attributedStrM.append(NSAttributedString(string: String(format: "%.3f", totalFees), attributes: [NSAttributedString.Key.foregroundColor: UIColor.hexadecimalColor(hexadecimal: "#F1B11B")]))

attributedStrM.append(NSAttributedString(string: NSLocalizedString("个",  comment: "")+"\n\n", attributes: [NSAttributedString.Key.foregroundColor:ThemeColor.sharedInstance.getGrayTextWhiteColor()]))

//到账数量  //"\(all - totalFees)"

attributedStrM.append(NSAttributedString(string: String(format: "%.3f", all), attributes: [NSAttributedString.Key.foregroundColor: QBColor_Orange]))

attributedStrM.append(NSAttributedString(string: " \(self.currentCurrency!)", attributes: [NSAttributedString.Key.foregroundColor:ThemeColor.sharedInstance.getGrayTextWhiteColor()]))

self.rightTipLabel?.textAlignment = NSTextAlignment.right

self.rightTipLabel!.attributedText = attributedStrM

self.rightTipLabel?.numberOfLines = 0

DispatchQueue.main.async {

self.bottomTipLabel!.text = NSLocalizedString("手续费率", comment: "") + "\(self.feeS)" + ", " + NSLocalizedString("单笔不超过", comment: "") + "\(self.firstFee)" + "\(self.currentCurrency!)" + NSLocalizedString("多少手续费", comment: "")

}

self.view.layoutIfNeeded()

}
