我的问题类似于＆＃34; How can I prevent iOS apps from resetting after changing Camera permissions?＆＃34;。 但我不太清楚答案。
我按照以下代码设置麦克风权限：
的
的 - （BOOL）canRecord
{
__block BOOL bCanRecord = NO;
AVAuthorizationStatus authStatus = [AVCaptureDevice authorizationStatusForMediaType：AVMediaTypeAudio];
if (authStatus == AVAuthorizationStatusRestricted || authStatus ==AVAuthorizationStatusDenied)
{
//prompt
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"setting permission" message:@"need microphone permission" preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *settingAction = [UIAlertAction actionWithTitle:@"setting now" style:UIAlertActionStyleDefault handler:^(UIAlertAction * a){
// jump to setting
NSURL * url = [NSURL URLWithString:UIApplicationOpenSettingsURLString];
if ([[UIApplication sharedApplication] canOpenURL:url]) {
if ([[[UIDevice currentDevice]systemVersion]floatValue]>10.0) {
[[UIApplication sharedApplication] openURL:url options:@{} completionHandler:nil];
} else {
[[UIApplication sharedApplication] openURL:url];
}
}
}];
UIAlertAction *okAction = [UIAlertAction actionWithTitle:@"later" style:UIAlertActionStyleDefault handler:nil];
[alertController addAction:settingAction];
[alertController addAction:okAction];
[self presentViewController:alertController animated:YES completion:nil];
}else{
if ([[[UIDevice currentDevice]systemVersion]floatValue] >= 7.0) {
AVAudioSession *audioSession = [AVAudioSession sharedInstance];
[audioSession performSelector:@selector(requestRecordPermission:) withObject:^(BOOL granted) {
if (granted) {
bCanRecord = YES;
} else {
bCanRecord = NO;
}
}];
// }
}
NSLog(@"bCanRecord %d",bCanRecord);
}
return bCanRecord;
}
的
然后点击状态栏中的返回键返回我的应用，我的应用会强制刷新，我将在应用中失去我的位置。
我正在使用运行IOS 9.3.3的iPhone5。
