MKMapview
当前用户位置未在iOS-8
,之前iOS-7
& iOS-6
工作正常。
self.mapView.delegate = self;
self.mapView.showsUserLocation =YES;
在此行中自动调用用户当前位置委托方法
- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations{
}
但不会在iOS-8
中触发。

在iOS8中,您需要在获取用户位置之前请求用户授权。
有两种要求:
-[CLLocationManager requestWhenInUseAuthorization]
可让您吸引用户'仅在应用程序被唤醒时的位置。
-[CLLocationManager requestAlwaysAuthorization]
可让您吸引用户'位置,即使它在后台。
您可以相应地选择它们。
例如,在开始更新位置之前将其放入:
// ask for authorization
CLLocationManager * locationManager = [[CLLocationManager alloc] init];
// check before requesting, otherwise it might crash in older version
if ([locationManager respondsToSelector:@selector(requestWhenInUseAuthorization)]) {
[locationManager requestWhenInUseAuthorization];
}
此外,不要忘记添加两个键
NSLocationWhenInUseUsageDescription
和
NSLocationAlwaysUsageDescription
进入你的info.plist。
将值保留为空以使用默认消息,或者您可以通过输入值来自定义自己的值。

在ios 8中需要授权,如下所示
NSString * osVersion = [[UIDevice currentDevice] systemVersion];
if ([osVersion floatValue]>= 8.0 ) {
[_CLLocationManager requestAlwaysAuthorization]; //Requests permission to use location services whenever the app is running.
// [_CLLocationManager requestWhenInUseAuthorization]; //Requests permission to use location services while the app is in the foreground.
}
[_CLLocationManager startUpdatingLocation];
你需要在plist中添加两个键
1.NSLocationAlwaysUsageDescription
2.NSLocationWhenInUseUsageDescription
答案 2 :(得分:0)
在iOS 8 Mapview当前位置使用
启动您可以在.plist文件中设置
<key>NSLocationWhenInUseUsageDescription</key>
<string>Your app name Or Other string</string>
<key>NSLocationAlwaysUsageDescription</key>
<string>Your app name Or Other string</string>
您的代码方面只是实现了这个
CLLocationManager * locationmanager = [CLLocationManager new];
locationmanager.delegate = self;
locationmanager.distanceFilter = kCLDistanceFilterNone;
locationmanager.desiredAccuracy = kCLLocationAccuracyBest;
[locationmanager startUpdatingLocation];
[locationmanager requestAlwaysAuthorization];
- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)位置 {
location = [locations objectAtIndex:0];
[locationmanager stopUpdatingLocation];
}
我正在使用此应用程序获取完美的当前位置。
