如何在iOS中查找蓝牙音频设备

首先，您需要配置您的应用程序允许蓝牙连接，支持音频的音频会话。你能做到的例如，您的应用程序代表-(BOOL) 应用程序:(UIApplication *) 应用程序 didFinishLaunchingWithOptions:(NSDictionary *) launchOptions 方法。请确保您 AVFoundation 框架联系起来，并将使用它的头中导入。
#import // place in .h

[self prepareAudioSession];// called from application didFinishLaunchingWithOptions

- (BOOL)prepareAudioSession {

// deactivate session
BOOL success = [[AVAudioSession sharedInstance] setActive:NO error: nil];
if (!success) {
NSLog(@"deactivationError");
}

// set audio session category AVAudioSessionCategoryPlayAndRecord options AVAudioSessionCategoryOptionAllowBluetooth
success = [[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayAndRecord withOptions:AVAudioSessionCategoryOptionAllowBluetooth error:nil];
if (!success) {
NSLog(@"setCategoryError");
}

// activate audio session
success = [[AVAudioSession sharedInstance] setActive:YES error: nil];
if (!success) {
NSLog(@"activationError");
}

return success;

}
