Question

我使用Privacy Prompts项目中的以下代码来获取动作权限。

- (void)requestMotionAccessData {
    self.cmManager = [[CMMotionActivityManager alloc] init];
    self.motionActivityQueue = [[NSOperationQueue alloc] init];
    [self.cmManager startActivityUpdatesToQueue:self.motionActivityQueue withHandler:^(CMMotionActivity *activity) {
        /* 
         * Do something with the activity reported
         */

        NSLog(@"requestMotionAccessData");
        [self alertViewWithDataClass:Motion status:NSLocalizedString(@"ALLOWED", @"")];
        [self.cmManager stopActivityUpdates];
    }];
}

如果用户不允许动作许可，该怎么办？我得到一些回调吗？如果没有，是否有另一种方法来实现这一目标。当用户选择Allow或Don't Allow

时，我想要回调

你可以......选择错误：

[stepCounter queryStepCountStartingFrom:[NSDate date]
                                     to:[NSDate date]
                                toQueue:[NSOperationQueue mainQueue]
                            withHandler:^(NSInteger numberOfSteps, NSError *error) {
                                if (error != nil && error.code == CMErrorMotionActivityNotAuthorized) {
                                    // The app isn't authorized to use motion activity support.
}

从这里开始：iOS - is Motion Activity Enabled in Settings > Privacy > Motion Activity

用户不允许权限时CMMotionActivityManager回调
