ios 城市定位
前言:
获取经纬度并且转换成城市
ios8定位失败解决
获取中文城市
1、建立简单的项目, 导入coreloation.framework
:
2、在info.plist
中加上nslocationalwaysusagedescription
值为alwayslocation
:
3、使用cllocationmanager
对象进行定位:

_locationmanger = [[cllocationmanager alloc] init];
_locationmanger.delegate = self;
[_locationmanger requestalwaysauthorization]; //ios8需要加上,不然定位失败
_locationmanger.desiredaccuracy = kcllocationaccuracybest; //最精确模式
_locationmanger.distancefilter = 100.0f; //至少10米才请求一次数据
[_locationmanger startupdatinglocation]; //开始定位
|
4、在cllocationmanagerdelegate
代理方法(ios8)中获取定位信息并且转换成中文城市:

// 保存 设备 的当前语言

// 强制 成 简体中文

clgeocoder * geocoder = [[clgeocoder alloc] init];
[geocoder reversegeocodelocation:newlocation completionhandler:^(nsarray *placemarks, nserror *error) {
for (clplacemark * placemark in placemarks) {
nsdictionary *test = [placemark addressdictionary];
// country(国家) state(城市) sublocality(区)
nslog(@ "%@" , [test objectforkey:@ "state" ]);
// 当前设备 在强制将城市改成 简体中文 后再还原之前的语言
[[nsuserdefaults standarduserdefaults] setobject:userdefaultlanguages forkey:@ "applelanguages" ];
}
}];
}

首次启动时,会提示是否开启定位并显示nslocationalwaysusagedescription
的值:
其中字典test的具体内容是:
