मैंने निम्नलिखित की कोशिश की और इसे कुछ भी आउटपुट करने में विफल रहता है मैं आदर्श रूप से स्ट्रिंग टेक्स्ट को एन गुणांक दोहराएगा जो इंट गुणक द्वारा मैं गलत क्या कर रहा हूं?

स्ट्रिंग टेक्स्ट और इंट गुणक को किसी अन्य विधि से तर्क के रूप में पारित किया जाता है।

<पूर्व> सार्वजनिक स्थिर स्ट्रिंग दोहराने पाठ (स्ट्रिंग टेक्स्ट, इंट गुणक) {स्ट्रिंग मान = ""; स्ट्रिंगबइल्डर दोहराना = नया स्ट्रिंगबइल्डर (टेक्स्ट। लांघ () * गुणक); दोहराएँ (दोहराएँ, पाठ, गुणक); value.equals (दोहराने); System.out.println ("टेक्स्ट दोहराया:"); Println ( "-----------"); Println (दोहराने); Println ( "--------------"); प्रतिलाभ की मात्रा; }

निम्न विधि आज़माएं: 

  सार्वजनिक स्थैतिक स्ट्रिंग दोहरा (स्ट्रिंग टू रीपीट, इंट टाइम) {यदि (torepeat == रिक्त) {toRepeat = "null"; } यदि (बार & lt; = 0) {वापसी ""; } स्ट्रिंगबिल्डर एस.बी. = नया स्ट्रिंगबिल्डर (); के लिए (int i = 0; i & lt; times; i ++) {sb.append (toRepeat); } वापसी sb.toString (); }

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.
