UISearchBar जैसा कि iMac खोजक खोज कार्यक्षमता

Question

जैसा कि मैंने एक आवश्यकता के साथ मुलाकात की जिसमें मेरे पास UISearchBar जैसा था।

चरण: 1 (SearchBar की प्रारंभिक देखो)

चरण: 2 (उपयोगकर्ता प्रकार स्ट्रिंग और तत्काल खोजें)

कदम: 3 (खोज सूची में उनमें से किसी का चयन करना)

कदम: 4

(SearchBar पर बटन जोड़ने से)

कदम: 5 (अंत में बटन पर कार्रवाई)

यह जारी हो सकता है। मेरा कहना है कि वह पाठ को और अधिक दर्ज कर सकता है लेकिन कार्यक्षमता एक जैसी होनी चाहिए।

क्या कोई मेरी मदद कर सकता है? कृपया, मुझे ज़रूरत है।

अद्यतन

आप अपने आईमैक खोजक खोजें

यह मैं क्या कोशिश की है है यह एक ही कार्यक्षमता देख सकते हैं।

अस्वीकरण: इस समाधान, गहरा त्रुटिपूर्ण है शायद कई मायनों में। यह पहला समाधान है जिसके साथ मैं आया था और मैंने इस पर बहुत कम अनुकूलन किया है (उर्फ कोई नहीं)।

तो, मैं ऊब गया था, और मैं ऐसा कुछ लेकर आया जो मुझे लगता है कि बिल फिट बैठता है। ध्यान रखें कि यह केवल उस चीज का प्रदर्शन करता है जो आप पूछ रहे हैं (और यह उस पर कुछ हद तक खराब है), यह वास्तविक खोज कार्यक्षमता को संभाल नहीं करता है क्योंकि मुझे यकीन नहीं है कि आप क्या खोज रहे हैं। इसमें कुछ स्थिर मान भी प्रोग्राम किए गए हैं (जैसे फाइल प्रकार सरणी, और मैंने व्यू कंट्रोलर को UINavigationController में गिरा दिया और उस पर आधारित कुछ स्थिर आकार) जिन्हें आप बदलना चाहते हैं। मैं WYPopoverController का उपयोग करता हूं, जो यहां पाया जा सकता है: WYPopoverController। मुझे बताएं कि यह आपके लिए कैसे काम करता है- अगर यह नरक की आलोचना करने के लिए स्वतंत्र महसूस करें।
