requestAuthorizationToShareTypes 方法在 iOS 8 Xcode 6 中不显示权限提示

Question

-(void)viewDidAppear:(BOOL)animated
{

[super viewDidAppear:animated];
if ([HKHealthStore isHealthDataAvailable]){
    NSSet *writeDataTypes = [self dataTypesToWrite];
    NSSet *readDataTypes = [self dataTypesToRead];

    [self.healthStore requestAuthorizationToShareTypes:writeDataTypes readTypes:readDataTypes completion:^(BOOL success, NSError *error) {

        NSLog(@"%s",__func__);
        if (!success) {
            NSLog(@"You didn't allow HealthKit to access these read/write data types. In your app, try to handle this error gracefully when a user decides not to provide access. The error was: %@. If you're using a simulator, try it on a device.", error);
            return;
        }

        dispatch_async(dispatch_get_main_queue(), ^{
            // Update the user interface based on the current user's health information.
            NSLog(@"=========================== %s",__func__);
        });
    }];
}


}

requestAuthorizationToShareTypes 不会回调完成方法。

我也遇到了类似的问题，权限框没有出现，并且没有正确设置 HKHealthStore，所以提前为我解决了这个问题

self.healthStore = [[HKHealthStore alloc] init];
