IOS开发—定位卡死bug解决

IOS开发—App 在 IOS 8 的simulator运行时，定位卡死bug解决
在 iOS 8 上编译会出现以下 log ：
Trying to start MapKit location updates without prompting for location authorization. Must call -[CLLocationManager requestWhenInUseAuthorization] or -[CLLocationManager requestAlwaysAuthorization] first.
经搜索得到解决方法如下：
1、修改info.plist：
? ? 新增key值为NSLocationWhenInUseUsageDescription 或 NSLocationAlwaysUsageDescription（这里，我将两个都加了进去），value可以为空，也可以设置YES，不过我得问题还是不能解决，较终还是找到得了问题所在，就是info.plist中还需要包含Supported interface orientations 这个Array字段。然后运行就解决了。
2、修改代码：
? ? 在调用方法startUpdatingLocation的前面加上一句
?
1
2
3	if([locationManager respondsToSelector:@selector(requestWhenInUseAuthorization)]) {
????[locationManager requestWhenInUseAuthorization];
}
3、博客原文修改方法：

????????locationManager.delegate = self;
????????locationManager.desiredAccuracy=kCLLocationAccuracyBest;
????????if([locationManager respondsToSelector:@selector(requestWhenInUseAuthorization)]) {
????????????[locationManager requestWhenInUseAuthorization];
????????}
????????[locationManager startUpdatingLocation];

?
????if (
????????([locationManager respondsToSelector:@selector(requestWhenInUseAuthorization)] && status != kCLAuthorizationStatusNotDetermined && status != kCLAuthorizationStatusAuthorizedWhenInUse) ||
????????(![locationManager respondsToSelector:@selector(requestWhenInUseAuthorization)] && status != kCLAuthorizationStatusNotDetermined && status != kCLAuthorizationStatusAuthorized)
????????) {
?
????????NSString *message = @"您的手机目前并未开启定位服务，如欲开启定位服务，请至设定->隐私->定位服务，开启本程式的定位服务功能";
????????UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"无法定位" message:message delegate:nil cancelButtonTitle:@"确定" otherButtonTitles: nil];
????????[alertView show];
?
????}else {
?
????????[locationManager startUpdatingLocation];
????}
}
上面那行是 iOS 8 以上，*二行是 iOS 7 以下，因为 kCLAuthorizationStatusAuthorized 在 iOS 8 完全不能使用。

????// 开始定位

}else {

????// 显示警告
