推荐答案

在iOS上目前有两种方式发送/接收文件通过蓝牙。第一种方式是在它使用外部附件框架蓝牙经典。但这不过需要您连接到是MFI设备启用，它（据​​我所知）没有Android的手机。另一种方法是在其上使用核心蓝牙框架BLE（蓝牙低功耗）。 BLE的设计是非常低的功率，因而有一个pretty低吞吐量。它可以超过它虽然发送大型文件（如图片），但你可能将不得不削减在小片图像和数据缝合到一起在接收端。你可以阅读这里的蓝牙核心编程指南的框架：<一href=\"https://developer.apple.com/library/ios/documentation/NetworkingInternetWeb/Conceptual/CoreBluetooth_concepts/CoreBluetooth_concepts.pdf\" rel=\"nofollow\">https://developer.apple.com/library/ios/documentation/NetworkingInternetWeb/Conceptual/CoreBluetooth_concepts/CoreBluetooth_concepts.pdf

On iOS there are currently two ways to send/receive files over Bluetooth. The first way is over Bluetooth Classic which uses the External Accessory Framework. This does however require that the device you are connected to is MFi enabled, which (to the best of my knowledge) no Android-phone is. The other way is over BLE (Bluetooth Low Energy) which uses the Core Bluetooth Framework. BLE is designed to be very low power and thus have a pretty low throughput. It is possible to send larger files (like images) over it though, but you will probably have to cut the image in smaller pieces and stitch the data back together on the receiver side. You can read about the framework in the Core Bluetooth Programming Guide here: https://developer.apple.com/library/ios/documentation/NetworkingInternetWeb/Conceptual/CoreBluetooth_concepts/CoreBluetooth_concepts.pdf
