iOS8中webview添加定位功能

1.导入头文件 #import <CoreLocation/CoreLocation.h>

2.在info.plist中设置配置

NSLocationWhenInUseDescription

NSLocationAlwaysUsageDescription

3.在webview需要定位的地方添加如下代码

@property (nonatomic, strong) CLLocationManager *locationMgr;
  if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8) {

                //由于IOS8中定位的授权机制改变 需要进行手动授权
                  self.locationMgr = [[CLLocationManager alloc] init];

                  //获取授权认证
                  [self.locationMgr requestAlwaysAuthorization];
                  [self.locationMgr requestWhenInUseAuthorization];
       }
