iphone - Sort an NSArray in Descending Order -


हे लोग, मेरे पास NSArray का NSNumber ऑब्जेक्ट है I 

  [myArray sortedArrayUsing Selecter: @selector (तुलना करें :))

हालांकि, मुझे यह सॉर्ट करने की ज़रूरत है अवरोही आदेश मैं इसे लेता हूं कि तुलना करें: केवल आरोही क्रम में ही। जबकि मैं NSArray को पीछे करने के बारे में जा सकता हूं, मैं इस बारे में उत्सुक हूँ कि क्या ऐसा करने के बारे में जाने में अधिक सरल या अधिक प्रभावी तरीका है।

धन्यवाद!

संपादित करें : मैंने पाया जो कि एक NSArray : 

  के लिए दोबारा उल्टा करने के लिए एक सरल तरीका प्रदान करता है (id someObject [ MyArray reverseObjectEnumerator])

यह काम करता है ठीक है, मुझे लगता है कि यह एक अच्छा सरल समाधान है, लेकिन मैं उत्सुक हूँ कि क्या कोई क्रम अवरोही क्रम में सॉर्ट करने का तरीका है या नहीं।

एक प्रकार का वर्णनकर्ता का उपयोग करें 

  NSSortDescriptor * sortOrder = [NSSortDescriptor sortDescriptorWithKey: @ "आत्म" आरोही: नहीं]; वापसी [myArray सॉर्ट किया गयाअरेज़उपकरणडिस्क्रिप्टरः [एनएसएआरआरएआरएरेओब्जेक्ट: सॉर्टऑर्डर]];

php - How to paginate multiple results in CakePHP? -

How can I use the Pageinization Assistant in KPHPH to set more than one result on the same page? They will do the page independently Edit: I have found a reason why it can not do this because because the page will get its URL from the assistant controller / verb and after that Finally add its parameters. If it pulls the URL from the address bar, it has its own unique variable and then a straw_rele is used to navigate to the next one if you have already placed the page, or if it is not present in it Now, I'm thinking of re-writing assistant to support this feature to support this feature, but I'm not sure if I need it or if they are already I support it and I am doing it wrong Here's my solution in your controller: function index () {// your default model is $ $ this- & gt; Set ('model1', $ this- & gt; paginated)); // Endorsement for Model 2- $ this- & gt; Set ('Model2', $ this- & gt; Paginated ('Model2')); } In your ...

I'm trying to display the file name in a listbox, taken from a special directory.
