swift代码片段

http使用

 <key>NSAppTransportSecurity</key>
    <dict>
        <key>NSAllowsArbitraryLoads</key>
        <true/>
    </dict>

log去除AQDefaultDevice (173): skipping input stream 0 0 0x0
选择 Product -->Scheme-->Edit Scheme; 选择 Arguments; 在Environment Variables添加一个环境变量 OS_ACTIVITY_MODE 设置值为 disable
ok
status的颜色设置

<key>UIViewControllerBasedStatusBarAppearance</key>
    <false/>

顶部状态栏文字变白色
UIApplication.shared.setStatusBarStyle(UIStatusBarStyle.lightContent, animated: false)
状态栏背景颜色：self.navigationController?.navigationBar.barTintColor
隐藏状态栏：info.plist下面加

    <key>UIStatusBarHidden</key>
    <true/>
    <key>UIViewControllerBasedStatusBarAppearance</key>
    <false/>

4 // 手机振动一下

AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);

5 // 返回颜色

self.navigationController?.navigationBar.tintColor = UIColor.white

6 返回文字省略

// 设置返回文字,不然太长了
let item = UIBarButtonItem(title: "返回", style: .plain, target: self, action: nil)
self.navigationItem.backBarButtonItem = item;

7 键盘上面添加一个收起键盘的按钮，比如说：完成，当然也可以添加上一项、下一项的按钮：点击完成时，只是负责键盘的收起：

func AddToolBar() -> UIToolbar {
    let toolBar:UIToolbar = UIToolbar(frame: CGRect(x: 0, y: 0, width: self.view.frame.width, height: 35))
    toolBar.backgroundColor = UIColor.gray
    let spaceBtn = UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: nil, action: nil)
    let barBtn = UIBarButtonItem(title: "完成", style: .plain, target: self, action: #selector(doneNum))
    toolBar.items = [spaceBtn, barBtn]
    return toolBar
}

func doneNum() {
    self.view.endEditing(false)
}
// 加上
//outPlTextField.inputAccessoryView = AddToolBar()

8 字符串替换

var s = data.replacingOccurrences(of: "{\"code\":\"0\",\"data\":[", with: "[")
s = s.replacingOccurrences(of: "}]}", with: "}]")

9 大小
上44+20，底部导航44，下图片25/50/75，上按钮

10 时间显示 2017-10-15 16:53:02

let ctime = Date()
let dformatter = DateFormatter()
dformatter.dateFormat = "【YYYY-MM-dd hh:mm:ss】"
dformatter.timeZone = NSTimeZone.system
let strTime = dformatter.string(from: ctime)
print(strTime)

11 更新本地仓库pod install --repo-update, pod update
12 拷贝到剪切板

let paste = UIPasteboard.general
paste.string = str

13 点击任意位置，取消键盘

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
        self.view.endEditing(false)
    }
