小编Mo *_*eed的帖子

我正在尝试将我的应用升级到最新的iOS支持.我通过CocoaPods添加了TwitterKit,并将标题放在我的Bridge Header中.然而; 我收到一个错误说:

使用未解决的'推特' - 你的意思是'TWTRTTwitter'.

func application(_ application: UIApplication, didFinishLaunchingWithOptions lauunchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    Twitter.sharedInstance().start(withConsumerKey:"MYKEY", consumerSecret:"MYSECRET")
    return true
}

这是推特推荐的代码.我也得到了:

func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {

    let handled:Bool = true

    Twitter.sharedInstance().application(app, open: url, options: options)

    return handled
}

有什么指针吗？

我正在我的一个UIViewController上测试viewDidLoad事件.

- (void)testMyView
{
    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
    MyViewController *vc = [storyboard instantiateViewControllerWithIdentifier:MYID];
    [vc viewDidLoad];

    STAssertNotNil(vc, @"MyViewController should not be nil");
}

如果我删除该行[vc viewDidLoad];,viewDidLoad则永远不会触发.

如果我让位[vc viewDidLoad];,viewDidLoad则触发两次.

我知道视图是延迟加载的,但我怎么能避免这种行为呢？

有关View测试的最佳实践吗？

嗨，我已经按照swift的电话号码auth教程进行了操作，这是我的代码：

import UIKit
import FirebaseAuth

class SignInViewController: UIViewController {

@IBOutlet weak var number: UITextField!

override func viewDidLoad() {
    super.viewDidLoad()


    let myColor : UIColor = UIColor.white
    number.layer.borderWidth = 2.0
    number.layer.borderColor = myColor.cgColor
    number.layer.cornerRadius = 15.0
    number.attributedPlaceholder = NSAttributedString(string :"Enter your number", attributes : [NSForegroundColorAttributeName : UIColor.white] )

}

@IBAction func sendCode(_ sender: Any){
    let alert = UIAlertController(title: "Phone Number", message: "Is this your phone number? \n \(number.text!)", preferredStyle: .alert)

    let action = UIAlertAction(title: "Yes", style: .default) {(UIAlertAction) in
        PhoneAuthProvider.provider().verifyPhoneNumber(self.number.text!){ (verificationID, error) …
