IOS8下，百度地图无法定位解决办法(为啥苹果手机百度地图定不了位)

1.*需要在文件中添加(以下二选一，两个都添加默认使用NSLocationWhenInUseUsageDescription):

*NSLocationWhenInUseUsageDescription 允许在前台使用时获取GPS的描述

*NSLocationAlwaysUsageDescription 允许永远可获取GPS的描述

2.在调用百度SDK定位之前，先运行如下代码:

@property (nonatomic, strong) CLLocationManager *locationManager;

if ([[UIDevice currentDevice].systemVersion floatValue] >= ) {
//由于IOS8中定位的授权机制改变 需要进行手动授权
CLLocationManager *locationManager = [[CLLocationManager alloc] init];
//获取授权认证
[locationManager requestAlwaysAuthorization];
[locationManager requestWhenInUseAuthorization];
}
