标签: xcode6-beta5

我有一个适用于Xcode6-Beta1和Xcode6-Beta2的iOS7和iOS8应用程序.但是对于Xcode6-Beta3,Beta4,Beta5,我正面临着iOS8的网络问题,但在iOS7上一切正常.我收到了错误"The network connection was lost.".错误如下:

错误:错误域= NSURLErrorDomain代码= -1005"网络连接丢失." UserInfo = 0x7ba8e5b0 {NSErrorFailingURLStringKey =,_ kCFStreamErrorCodeKey = 57,NSErrorFailingURLKey =,NSLocalizedDescription =网络连接丢失.,_ kCFStreamErrorDomainKey = 1,NSUnderlyingError = 0x7a6957e0"网络连接丢失."}

我使用AFNetworking 2.x和以下代码片段进行网络调用:

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager setSecurityPolicy:policy];
manager.requestSerializer = [AFHTTPRequestSerializer serializer];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];

[manager POST:<example-url>
   parameters:<parameteres>
      success:^(AFHTTPRequestOperation *operation, id responseObject) {
          NSLog(@“Success: %@", responseObject);
      } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
          NSLog(@"Error: %@", error);
      }];

我试过NSURLSession但仍然收到同样的错误.

突然,我开始得到运行时错误,因为,

fatal error: NSArray element failed to match the Swift Array Element type

我宣布我的阵列为,

var myArray : [CUSTOM_CLASS] = [CUSTOM_CLASS]()

现在,在我的服务器响应成功块中,

self.myArray = dicResponse["data"]! as Array

println(self.myArray) // FATAL ERROR HERE

在升级到Xcode6 Beta6之前,这是完美的

FYI : dicResponse["data"]! // is verified as valid

(抱歉指向错误的地方!)

解决了 :

不知道,但我做了一些改变,它的工作原理,

var myArray = [AnyObject]()

self.myArray = dicResponse["data"]! as [AnyObject]

我想在我的应用程序顶部创建一个导航栏.我创建了一个导航控制器 - >标签栏控制器 - >导航控制器 - >表控制器

1. 我在右上方拖了一个Bar Button Item.
2. 我双击表控制器中间的标题并写了一个文本.

3. 我也在我的控制器的viewDidLoad()中使用此代码尝试了它:

   self.navigationController.navigationBar.topItem.title = "some title"
   self.navigationItem.setRightBarButtonItem(UIBarButtonItem(barButtonSystemItem: .Search, target: self, action: "barButtonItemClicked:"), animated: true)
   self.navigationItem.title = "YourTitle"

它不起作用 - 我做错了什么？:/

我在Swift中使用泛型类和NSCoding(XCode beta 5)时遇到了问题.具体来说,这个示例代码很好地工作:

class Foo : NSObject, NSCoding
{
    let bar: String
    init(bar: String){
        self.bar = bar;
    }

    func encodeWithCoder(aCoder: NSCoder!){
        aCoder.encodeObject(bar, forKey: "bar")
    }
    required init(coder aDecoder: NSCoder!){
        self.bar = aDecoder.decodeObjectForKey("bar") as String
        super.init()
    }


}

let foo = Foo(bar: "hello, world")

NSKeyedArchiver.archiveRootObject(foo, toFile: "test.dat")

但是,当我尝试相同的代码,并添加一个通用参数; 当我尝试编码对象时; 我收到一个'无法识别的选择器发送到实例'错误:

class Foo<T> : NSObject, NSCoding
{
    let bar: String
    init(bar: String){
        self.bar = bar;
    }

    func encodeWithCoder(aCoder: NSCoder!){
        aCoder.encodeObject(bar, forKey: "bar")
    }
    required init(coder aDecoder: NSCoder!){
        self.bar = aDecoder.decodeObjectForKey("bar") as String …

我设法找出iOS 8下自我调整集合视图单元格的方法.

我想将此作为附件视图的一部分.

我遇到了崩溃...... stacktrace的有趣部分如下:

我有一个动作表,我在ios8(xcode 6 beta 5)中使用UIAlertcontroller进行演示.我正在使用UIAlertcontroller,因为UIActionsheet(在iOS 8中已弃用)在ios8中无法正常工作,单击操作表中的任何选项都会导致我回到父视图.现在我也面临着UIAlertcontroller中的一个问题,在操作表弹出窗口外面双击会让我回到上一个父视图.以下是我的代码段:

UIAlertController *actionSheetIos8;

actionSheetIos8 = [UIAlertController alertControllerWithTitle:nil message:nil preferredStyle:UIAlertControllerStyleActionSheet];

NSArray *buttonsArray = [self returnMoreArray];
int startY = 10;
for (int i = 0; i < [buttonsArray count]; i++) {

    UIAlertAction *defaultAction = [UIAlertAction actionWithTitle:[buttonsArray objectAtIndex:i] style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
        NSString *newStr = [buttonsArray objectAtIndex:i];
        newStr = [[newStr lowercaseString] stringByReplacingOccurrencesOfString:@" " withString:@"_"];
    }];
    [actionSheetIos8 addAction:defaultAction];        
}
UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleCancel handler:^(UIAlertAction *action) {
}];

[actionSheetIos8 setModalPresentationStyle:UIModalPresentationPopover];
UIPopoverPresentationController *popPresenter = [actionSheetIos8
                                                 popoverPresentationController];
popPresenter.sourceView = sender;
popPresenter.sourceRect …

我正在使用Swift与Typhoon和Cocoapods.一切顺利,直到我开始为我的Typhoon组件编写Integrationtest(根据Typhoon-Example-App测试).我想以与我在TyphoonFactory中的setUp() 方式相同的方式设置Test 方法AppDelegate.当我执行测试时,我总是得到一个

TyphoonBlockComponentFactory assertIsAssembly:] + 244:错误:MyApp.MyAssembly不是TyphoonAssembly的子类

Typhoon引发的错误(使用kindOfClass引擎盖下的方法.)相同的代码完美地工作AppDelegate,我无法弄清楚什么是错的.

为了验证这种行为,我实现了isKindOfClass检查booth类(参见下面的代码):

• AppDelegate - > true
• MyComponentTest - > false

有人可以帮助我吗？多谢!
