CLLocationManagerDelegate委托在8.1中未调用iOS

我在静态库中使用CLLocationManagerDelegate，当我在iOS 7设备上运行时，一切都很好，但当我在另一台iOS 8.1.3设备上测试它时，委托方法不会被调用。 我赚了一大笔钱 @属性（非原子，强）CLLocationManager locationManager 我还在info.plist中添加了相应的键和字符串值（NSLocationAlwaysUsageDescription，requestAlwaysAuthorization） 这就是我的例子

self.locationManager = [[CLLocationManager alloc] init];
[self.locationManager setDelegate:self];
self.locationManager.distanceFilter = kCLDistanceFilterNone; 
self.locationManager.desiredAccuracy = kCLLocationAccuracyBest;
[self.locationManager startUpdatingLocation];
[self.locationManager requestWhenInUseAuthorization];
[self.locationManager requestAlwaysAuthorization];

if([self.locationManager respondsToSelector:@selector(requestAlwaysAuthorization)]) {
}
[self.locationManager startUpdatingLocation];

请帮助我找出为什么没有调用委托方法！！

为什么我没有得到位置更新

我希望这对你有帮助。调用

[locationManager RequestWhenUseAuthorization]

内部

if（）…

if ([CLLocationManager locationServicesEnabled])
{
    locationManager = [[CLLocationManager alloc] init];

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

    UIAlertView *servicesDisabledAlert = [[UIAlertView alloc] initWithTitle:@"Location Services Disabled" message:@"You currently have all location services for this device disabled. If you proceed, you will be showing past informations. To enable, Settings->Location->location services->on" delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:@"Continue",nil];
    [servicesDisabledAlert show];
    [servicesDisabledAlert setDelegate:self];
}


- (void)requestWhenInUseAuthorization
{
CLAuthorizationStatus status = [CLLocationManager authorizationStatus];

// If the status is denied or only granted for when in use, display an alert
if (status == kCLAuthorizationStatusAuthorizedWhenInUse || status == kCLAuthorizationStatusDenied) {
    NSString *title;
    title = (status == kCLAuthorizationStatusDenied) ? @"Location services are off" : @"Background location is not enabled";
    NSString *message = @"To use background location you must turn on 'Always' in the Location Services Settings";

    UIAlertView *alertViews = [[UIAlertView alloc] initWithTitle:title
                                                        message:message
                                                       delegate:self
                                              cancelButtonTitle:@"Cancel"
                                              otherButtonTitles:@"Settings", nil];
    [alertViews show];
}
// The user has not enabled any location services. Request background authorization.
else if (status == kCLAuthorizationStatusNotDetermined) {
    [locationManager requestWhenInUseAuthorization];
}
}


if ([alertView.message isEqualToString:@"To use background location you must turn on 'Always' in the Location Services Settings"])
{
    if (buttonIndex == 1)
    {
        // Send the user to the Settings for this app
        NSURL *settingsURL = [NSURL URLWithString:UIApplicationOpenSettingsURLString];
        [[UIApplication sharedApplication] openURL:settingsURL];
    }
}

您必须添加 NSLocationAlwaysUsageDescription或nsLocationWhenUsageDescription在您的Plist文件中，带有一些消息“此应用程序需要您的位置”

对于iOS 8，您需要在Info.plist中定义“隐私-位置使用说明”

例如，隐私-位置使用说明=“使用您的位置显示附近的商店”

---

此键指定访问用户位置信息的原因。

对于iOS 8，您需要在Info.plist中定义“隐私-位置使用说明”

locationManager = [[CLLocationManager alloc] init];

[locationManager setDesiredAccuracy:kCLLocationAccuracyBest];
[locationManager setDistanceFilter:5];

if ([locationManager respondsToSelector:@selector(requestAlwaysAuthorization)]) {
    [locationManager requestAlwaysAuthorization];
}

[locationManager startUpdatingLocation];

您能在控制台输出中看到类似以下消息的内容吗

locationManager = [[CLLocationManager alloc] init];

[locationManager setDesiredAccuracy:kCLLocationAccuracyBest];
[locationManager setDistanceFilter:5];
[locationManager setHeadingFilter:5];
[locationManager setDelegate:self];

if ([locationManager respondsToSelector:@selector(requestAlwaysAuthorization)]) {
    [locationManager requestAlwaysAuthorization];
}

[locationManager startUpdatingLocation];

Trying to start MapKit location updates without prompting for location authorization. Must call -[CLLocationManager requestWhenInUseAuthorization] or -[CLLocationManager requestAlwaysAuthorization] first.

我第一次将我的应用程序移植到iOS8时遇到了这个问题。定义以下键有一个新的限制

    /* Localized versions of Info.plist keys */

"NSLocationWhenInUseUsageDescription" = "for some reason, your app will use your location whenever the app is in foreground";

"NSLocationAlwaysUsageDescription" = "for some reason, your app will use your location whenever the app is in background";

这些键必须在项目根目录中名为InfoPlist.strings的可本地化字符串文件中定义。有一次我把这个文件放错了位置，花了很长时间才弄清楚问题出在哪里

下一件事是，您应该检查您请求授权的CLLocationManager的生存期是否未超过处理用户确认的时间。例如，在AppDelegate中定义全局CLLocationManager

我希望这有帮助， 亲切问候,，

并将以下代码添加到.plist文件中

NSLocationAlwaysUsageDescription=Application would like to use your location

NSLocationAlwaysUsageDescription=Application would like to use your location

这将调用CLLocationManager的所有委托方法。这将调用CLLocationManager的所有委托方法。是否将代码从

requestwhenUseAuthorization

更改为您的

requestAlwaysAuthorization

在

-（void）locationManager:（CLLocationManager*）中标记断点更新位置：（CLLocation*）newLocation fromLocation:（CLLocation*）oldLocation这是由
[locationManager RequestWhenUseAuthorization]调用的；
根本没有发生任何事情，因为委托方法根本没有得到调用，只需在接口
CLLocationManager*locationManager；
中的.h文件
@property中声明即可（非原子，保留）CLLocationManager*locationManager；
或在.m文件界面中
CLLocationManager*locationManager；
是否将代码从使用授权时的

谢谢peter的回答，但我的控制台中没有收到任何错误消息：/我已在plist中添加了此键，在appDelegate中也添加了CLLocation，但我始终有一个空值CLLocationManager和never获取位置..谢谢peter的回答，但我的控制台中没有收到任何错误消息：/i已经在plist中添加了此键，在appDelegate中也添加了CLLocation，但我始终有CLLocationManager的空值，并且从未获取位置..这对med很有帮助。问题的键是
nsLocationWhenUsageDescription
帮助医疗。问题的关键是
nslocationwhenUsageDescription
。
