CMPedometer StepCounting not Available

问题

My code is:

if ([CMPedometer isStepCountingAvailable]) {

        self.pedometer = [[CMPedometer alloc] init];
    }
    else {
        NSLog(@"Step counting is not available on this device!");
        [SVProgressHUD showErrorWithStatus:@"Step counting is not available on this device!"];
    }

When i run it on iOS8 and later devices, it says:

Step counting is not available on this device!

How can i make it available for step counting ?

回答1:

Your code is correct and it yields the expected result. The iPhone 5 does not have the hardware (the Apple M7 chip) to track steps, so step counting is not available.

You need at least an iPhone 5s

回答2:

The iPhone 4s, 5 and 5c do not have the M7 Motion Sensor co-processor so they will not record steps. The iPhone 5s, 6 and 6 Plus all have a motion co-processor.
