我的应用在iOS 7上运行良好,但在iOS 8 SDK上却无法运行。
CLLocationManager不返回位置,我没有看到我的应用程序下设置->位置服务。我在这个问题上做了谷歌搜索,但没有任何结果。会有什么问题呢?

保持可可钥匙信息总是在你的指尖为这些更新,这里是链接:

我的解决方案可以在Xcode 5中编译:
#ifdef __IPHONE_8_0
NSUInteger code = [CLLocationManager authorizationStatus];
if (code == kCLAuthorizationStatusNotDetermined && ([self.locationManager respondsToSelector:@selector(requestAlwaysAuthorization)] || [self.locationManager respondsToSelector:@selector(requestWhenInUseAuthorization)])) {
// choose one request according to your business.
if([[NSBundle mainBundle] objectForInfoDictionaryKey:@"NSLocationAlwaysUsageDescription"]){
[self.locationManager requestAlwaysAuthorization];
} else if([[NSBundle mainBundle] objectForInfoDictionaryKey:@"NSLocationWhenInUseUsageDescription"]) {
[self.locationManager requestWhenInUseAuthorization];
} else {
NSLog(@"Info.plist does not contain NSLocationAlwaysUsageDescription or NSLocationWhenInUseUsageDescription");
}
}
#endif
[self.locationManager startUpdatingLocation];
这是ios 8的问题 将此添加到代码中
if (IS_OS_8_OR_LATER)
{
[locationmanager requestWhenInUseAuthorization];
[locationmanager requestAlwaysAuthorization];
}
到info.plist:
<key>NSLocationUsageDescription</key>
<string>I need location</string>
<key>NSLocationAlwaysUsageDescription</key>
<string>I need location</string>
<key>NSLocationWhenInUseUsageDescription</key>
<string>I need location</string>
苹果的文件显示:
https://developer.apple.com/documentation/corelocation/requesting_permission_to_use_location_services https://developer.apple.com/documentation/corelocation/cllocationmanager/1620562-requestwheninuseauthorization
As of iOS 8, the presence of a NSLocationWhenInUseUsageDescription or a NSLocationAlwaysUsageDescription key value in your app's Info.plist file is required. It's then also necessary to request permission from the user prior to registering for location updates, either by calling [self.myLocationManager requestWhenInUseAuthorization] or [self.myLocationManager requestAlwaysAuthorization] depending on your need. The string you entered into the Info.plist will then be displayed in the ensuing dialog.
如果用户授予了权限,则业务照常进行。如果他们拒绝权限,则委托不会被告知位置更新。
在[locationManager startUpdatingLocation];之前,添加一个iOS8位置服务请求:
if([locationManager respondsToSelector:@selector(requestAlwaysAuthorization)])
[locationManager requestAlwaysAuthorization];
编辑应用程序的信息。并添加键NSLocationAlwaysUsageDescription与字符串值,将显示给用户(例如,我们尽我们最大的努力来保持您的电池寿命。)
如果你的应用程序只在应用程序打开时需要位置服务,请替换:
requestAlwaysAuthorization with requestWhenInUseAuthorization和
NSLocationAlwaysUsageDescription和NSLocationWhenInUseUsageDescription。
添加关键NSLocationWhenInUseUsageDescription或NSLocationAlwaysUsageDescription(后台GPS使用)字符串要求使用GPS在每个信息。Plist从每个目标。 通过运行命令获得许可: (自我initLocationManager: locationManager);
其中“initLocationManager”为:
// asks for GPS authorization on iOS 8
-(void) initLocationManager:(CLLocationManager *) locationManager{
locationManager = [[CLLocationManager alloc]init];
if([locationManager respondsToSelector:@selector(requestAlwaysAuthorization)])
[locationManager requestAlwaysAuthorization];
}
记住,如果键不是在每个信息上。Plist为每个目标,应用程序将不会询问用户。if提供了与iOS 7的兼容性,respondsToSelector:方法保证了未来的兼容性,而不仅仅是解决iOS 7和8的问题。
