1解决方法：
1）在RSADataSigner.m文件中 搜索代码 [result appendString:@"-----BEGIN PRIVATE KEY-----\n"]; 将其改成 [result appendString:@"-----BEGIN RSA PRIVATE KEY-----\n"];
2）在RSADataSigner.m文件中 搜索代码 [result appendString:@"\n-----END PRIVATE KEY-----"]; 将其改成 [result appendString:@"\n-----END RSA PRIVATE KEY-----"];

获取CLLocationManager定位权限
kCLAuthorizationStatusNotDetermined 用户没有做出选择
kCLAuthorizationStatusRestricted    无法使用定位服务，该状态用户无法改变
kCLAuthorizationStatusDenied        用户拒绝该应用使用定位服务或是定位服务总开关处于关闭状态

iOS 8
kCLAuthorizationStatusAuthorizedAlways  用户同意程序在可见时使用地理位置
kCLAuthorizationStatusAuthorizedWhenInUse 用户允许该程序运行时可以使用地理信息
kCLAuthorizationStatusAuthorized    用户允许该程序无论何时都可以使用地理信息

    if ([CLLocationManager authorizationStatus] == kCLAuthorizationStatusDenied  ) {
        //用户已拒绝开启定位服务，处理逻辑...
        //前往 开启定位授权
            if (floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_7_1) {

                UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"提示" message:@"请在iPhone的“设置->隐私->位置”中允许访问位置信息" delegate:self cancelButtonTitle:nil otherButtonTitles:@"取消", @"设置", nil];
                [alertView show];
            }else{
                kTipsAlert(@"请在iPhone的“设置->隐私->位置”中允许访问位置信息");
            }

    }else{
        //用户已同意开启定位服务，处理逻辑...
    }

直接跳转到该App设置页面，就是这样。

   NSURL *settingsURL = [NSURL URLWithString:UIApplicationOpenSettingsURLString];
   if ([app canOpenURL:settingsURL]) {
       [app openURL:settingsURL];
   }
