ios简单实现如果没有开启定位,提示开启系统软件定位功能

if([CLLocationManager locationServicesEnabled] && [CLLocationManager authorizationStatus] == kCLAuthorizationStatusDenied) {//判断该软件是否开启定位

JJLog(@"没打开");

self.isAddress = YES;

UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:@"打开定位开关" message:@"请点击设置打开定位服务" delegate:self cancelButtonTitle:@"取消" otherButtonTitles:@"设置", nil];

[alertView show];

}else{

JJLog(@"打开");

}

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{

　　if (buttonIndex == 1) {

　　 NSURL *url = [NSURL URLWithString:UIApplicationOpenSettingsURLString];

　　 if ([[UIApplication sharedApplication] canOpenURL:url]) {

　　 [[UIApplication sharedApplication] openURL:url];

　　 }

　　 }

}
