रिमोट शटर संभालें

DeviceDelegate से remote-shutter events प्राप्त करें, संबंधित app-camera action चलाएँ और परिणाम को डिवाइस के साथ synchronize करें।

आवश्यकताएँ

• डिवाइस कनेक्टेड है और DeviceRemoteShutterAPI के अनुरूप है।
• app में NSCameraUsageDescription entry मौजूद है और वह camera authorization माँगता है।
• app अपना AVCaptureSession और photo-capture implementation संभालता है।

उपयोग के उदाहरण

SDK event flow साफ़ रखने के लिए उदाहरण app-camera की details को local methods में रखता है।

त्रुटि प्रबंधन

Permission न मिलने, storage उपलब्ध न होने या app camera के capture न कर पाने पर .photoFailed रिपोर्ट करें। App photo mode में प्रवेश न कर पाए या उससे बाहर निकल चुका हो, तो .exitedOrUnableToEnter रिपोर्ट करें।
