//判断相册权限
ALAuthorizationStatus author = [ALAssetsLibrary authorizationStatus];
if (author == kCLAuthorizationStatusRestricted || author ==kCLAuthorizationStatusDenied){
//无权限
if (([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0)) {
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"照片权限被禁用" message:@"请在iPhone的'设置-隐私-照片'中允许抖抖访问你的照片" preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleCancel handler:nil];
[alertController addAction:cancelAction];
[self presentViewController:alertController animated:YES completion:nil];
return;
}else{
UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:@"照片权限被禁用" message:@"请在iPhone的'设置-隐私-照片'中允许抖抖访问你的照片" delegate:self cancelButtonTitle:@"确定" otherButtonTitles:nil, nil];
[alertView show];
return;
}
}else{
//有相册权限
}
}else if (sourceType == UIImagePickerControllerSourceTypeCamera){
AVAuthorizationStatus authStatus = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeVideo];
if (authStatus == AVAuthorizationStatusRestricted || authStatus ==AVAuthorizationStatusDenied){
//无权限
if (([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0)) {
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"相机被禁用" message:@"请在iPhone的'设置-隐私-相机'中允许抖抖访问你的相机" preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleCancel handler:nil];
[alertController addAction:cancelAction];
[self presentViewController:alertController animated:YES completion:nil];
