创建用户时尝试更新实时数据库中的用户数据.这是我的代码:

const functions = require('firebase-functions');
const promise = require('request-promise');
const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);

var omitBy = require('lodash.omitby');
var isNil = require('lodash.isnil');

'use strict';

exports.userCreated = functions.auth.user().onCreate(event => {

  let request = admin.auth().getUser(event.data.uid)
  .then(function(user) {
    console.log("Successfully fetched user data: ", user.toJSON());

    var email, firstName, lastName, photoURL;

    for (var provider of user.providerData) {

      if (provider.email) {
        email = provider.email;
      }

      if (provider.photoURL) {
        photoURL = provider.photoURL;
      }

      if (provider.displayName) {
        const names = provider.displayName.split(' ');
        firstName = names[0];

        if (names.length > …

我正在努力将我的项目从AFNetworking转移到Alamofire.真的很喜欢这个项目.POST请求工作正常,但是,我在尝试发出GET请求时收到此错误.

这是一些示例代码:

class func listCloudCredntials(onlyNew onlyNew: Bool = true, includePending: Bool = true) -> Request {

    let parameters: [String: AnyObject] = includePending ? ["include_pending": "true"] : [:]

    let urlString = "https://myapp-staging.herokuapp.com/api/1/credntials"

    let token = SSKeychain.storedToken()

    let headers: [String: String] = ["Authorization": "Bearer \(token)"]

    return Alamofire.request(.GET, urlString, parameters: parameters, encoding: .JSON, headers: headers)
}

我收到此错误: -1005 The network connection was lost

但是,如果我将请求类型更改为.POST,则请求"正常".我收到401代码,但至少请求不会丢失网络连接.

我究竟做错了什么？

我正在使用AFNetworking进行POST请求.我需要等到完成块完成才能返回数据,我遇到了问题.

我有一个解决方案,直到我切换到AFNetworking:

int i = 0;

while (!done)
{
    [NSRunLoop.currentRunLoop runUntilDate:[NSDate dateWithTimeIntervalSinceNow:0.1]];
    i++;

    NSLog(@"While Loop:%i", i);

    if (i == 149) //request timed out
        done = YES;
}

现在,解决方案偶尔会起作用.有时它只用NSLog(@"While Loop:%i", i);1或2记录完成,但有时它会记录到149并超时.似乎NSRunLoop有时会在不同的线程中运行,但有时会在阻止我的请求的同一线程上运行.

这是我目前的代码:

- (id)postRequestWithBaseURLString:(NSString *)baseURLString function:(NSString *)function parameters:(NSDictionary *)parameters
{
    if (baseURLString)
        function = [baseURLString stringByAppendingString:function];

    __block BOOL done = NO;
    __block id returnObject = nil;

    [self.manager POST:function parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject)
     {
         NSLog(@"Success: %@", responseObject);

         done = YES;
         returnObject = responseObject;
     }

          failure:^(AFHTTPRequestOperation *operation, NSError …

我在我的AppDelegate.m文件中有这个代码,didFinishLaunchingWithOptions:以便我可以有一个自定义字体.

[[UITabBarItem appearance] setTitleTextAttributes: [NSDictionary dictionaryWithObjectsAndKeys:
                                                        [UIColor grayColor], UITextAttributeTextColor,
                                                        [UIFont fontWithName:@"Gotham-Medium" size:10], UITextAttributeFont, nil] forState:UIControlStateNormal];

[[UITabBarItem appearance] setTitleTextAttributes: [NSDictionary dictionaryWithObjectsAndKeys:
                                                        [UIColor whiteColor], UITextAttributeTextColor,
                                                        [UIFont fontWithName:@"Gotham-Medium" size:10], UITextAttributeFont, nil] forState:UIControlStateHighlighted];

字体更改按预期工作,但我在调试控制台中获得此输出:

button text attributes only respected for UIControlStateNormal, UIControlStateHighlighted and UIControlStateDisabled. state = 1 is interpreted as UIControlStateHighlighted.

我在我的App Delegate中有这个代码:

[[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:@"Nav Bar.png"] forBarMetrics:UIBarMetricsDefault];

这很好用,但我使用它MFMailComposeViewController,我希望它具有默认的NavigationBar外观.

我怎么做？

编辑:

我试过这段代码:

[[UINavigationBar appearanceWhenContainedIn: [MFMailComposeViewController class], [UIViewController class], nil] setBackgroundImage:[UIImage imageNamed:@"Textured Background.png"] forBarMetrics:UIBarMetricsDefault];

我也试过只有这个代码.没有什么变化.默认导航栏,包括邮件视图控制器.

我认为它可能与之相关appearanceWhenContainedIn:.有谁知道MFMailComposeViewController会包含什么？

有没有办法同时设置多个属性？我试过这个:

dateTextField.font, nameTextField.font = [UIFont fontWithName:@"Gotham-Book" size:16];

但这得到了警告.我还能做些什么吗？

我有一个UITextView。我将委托myTextView设置为self，当我进行正常编辑时，此方法调用得很好：

- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text
{
    NSLog(@"Called");
}

在我的应用程序中，我调用我的代码：[myTextView insertText:@"Hello World"];。textView:shouldChangeTextInRange:replacementText:当我这样做时，我需要在插入文本后调用。我该怎么做呢？
