छवियों को भेजने के लिए बंप अपी पर कुछ मदद की ज़रूरत है

Question

मुझे यहां कुछ मदद की ज़रूरत है। मैं एक आईफोन से दूसरे में एक जेपीजी या पीएनजी छवियों को बंप के माध्यम से स्थानांतरित करना चाहता हूं। मुझे सफलता और असफलता का सामना करना पड़ा जहां छवियां बिल्कुल नहीं भेजी गईं।

नीचे एक NSObject फ़ाइल है जिसे उपयोगकर्ता द्वारा UIimagepicker से छवियों का चयन करने पर कॉल किया जाएगा।

रिसीवर कोई भी डेटा नहीं भेजा जाएगा बल्कि केवल प्राप्त होगा।

कृपया मुझे कोड पर नज़र डालने में मदद करें और मुझे कोई टिप्पणी या बिंदु दें।

धन्यवाद और आपकी सहायता की सराहना की।

मैंने पाया है कि 256k सीमा से अधिक छवियों को स्थानांतरित करने या किसी भी मात्रा में डेटा को टक्कर के माध्यम से, बहुत धीमा है। आपको पर्लोड को हिस्सों में बस्ट करना होगा और फिर प्रत्येक खंड को भेजे जाने और प्राप्त होने के बीच में देरी होगी। आप अपने स्वयं के वेब सर्वर है, तो यहाँ मैं क्या कर सकता है:

1. एप्लिकेशन वेब सेवा
2. वेब सेवा है किसी प्रकार का के माध्यम से अपने वेब सर्वर पर चित्र अपलोड करने के लिए एक आईडी या पथ वापसी अपलोड की गई फ़ाइल
3. टक्कर है कि जानकारी से अधिक है जो केवल कुछ कश्मीर में सबसे अच्छा
4. अनुप्रयोग के रिसीवर भाग अपने वेब सर्वर से छवि लाने है है

आप आश्चर्यचकित होंगे कि आपका स्थानांतरण कितना तेज़ होगा!
