javascript - Doing event.preventDefault() on $stateChangeStart creates a duplicate state -


एक और दो ui के साथ बनाए गए राज्य हैं यूआरएल / एक और / दो के साथ -उपकरण करें । मान लीजिए कि मैं निम्नलिखित राज्यों को नेविगेट करता हूं:

दो -> एक

(ब्राउज़र बार में मैं -> / एक )

फिर मैं वापस बटन पर क्लिक करता हूं, लेकिन वापस दो मैं जानबूझकर इस तरह के राज्य में परिवर्तन को रोकता हूं: 

  $ scope.firstTime = true; $ RootScope। $ ('$ StateChangeStart', फ़ंक्शन (ईवेंट, toState, toParam, fromState, पारामों से) {if ($ scope.firsttime) {event.preventDefault (); $ scope.firsttime = false;}});

अब मैं फिर से वापस पर क्लिक करता हूं, इस बार राज्य का परिवर्तन नहीं रोका जाता है, लेकिन दो पर वापस जाने के बजाय < Em> राइटर राज्य एक ( / एक ) पर रहता है .... अब अगर मैं वापस फिर से क्लिक करता हूं तो मैं वापस राज्य पर जा सकता हूं ( / two )।

मैं कैसे यूआई-राउटर को राज्य एक को पहली बार क्लिक करने से रोकूं पीठ ?

ios - How do I use CFArrayRef in Swift? -

I am using Objective-class in my Swift Project through a bridging header. The method signature looks like this: - Some cement (some type) some parameters; I started by getting an example of class, calling method, and storing the value: var myInstance = MyClassWithThatMethod (); Var cfArr = myInstance.someMethod (some value); Then try to get the value in the array: var valueInArrayThatIWant = CFArrayGetValueAtIndex (cfArr, 0); However, I get the error unmanaged & lt; Cfarray & gt; Not like 'CFArray' . Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
