मैं आईफोन कैमरा से वीडियो कैप्चर करने के लिए http://developer.apple.com/iphone/library/qa/qa2010/qa1702.html पर संदर्भ का पालन कर रहा हूं। यह उस पृष्ठ से कोड से अलग एक ताजा परियोजना है। मैंने परियोजना में AVFoundation ढांचे को भी जोड़ा। यहाँ है लिंकर त्रुटियों मैं:मेरे एक्सकोड 3.2.3 आईफोन 4.0.1 प्रोजेक्ट के साथ AVFoundation लिंक क्यों नहीं होगा?
