如何从CLGeocoder解析地标只显示城市

Question

我使用以下代码从CLGeocoder接收地标,我想在同一个viewcontroller上只显示另一个textview中的城市.我如何从这个阵列中解析出这座城市？它不是NSDictionary或任何东西,所以我不知道该怎么做.

CLGeocoder *geocoder = [[CLGeocoder alloc] init];

[geocoder reverseGeocodeLocation:location completionHandler:^(NSArray *placemarks, NSError *error) {
    NSLog(@"reverseGeocodeLocation:completionHandler: Completion Handler called!");
    if (error){
        NSLog(@"Geocode failed with error: %@", error);
        return;
    }
    NSLog(@"Received placemarks: %@", placemarks);
}];

我给定地标的日志如下:

<__ NSArrayM 0x1a0b3810>(937-961 Sunnyvale Saratoga Rd,937-961 Sunnyvale Saratoga Rd,Sunnyvale,CA 94087,United States @ + + 37.35984860,-122.03235910> +/- 100.00m)

要么

<__ NSArrayM 0x19576ac0>(5600 Van Nuys Blvd,5600 Van Nuys Blvd,Van Nuys,CA 91401-4602,United States @ <+ 34.17257000,-118.44794450> +/- 100.00m,region(identifier <+ 34.17257001,-118.44794464> radius 57.64)<+ 34.17257001,-118.44794464>半径57.64m)

我如何才能将Sunnyvale或Van Nuys的部分显示为字符串？

使用 CLPlacemark's properties

CLGeocoder * geoCoder = [[CLGeocoder alloc] init];
[geoCoder reverseGeocodeLocation:yourLocation completionHandler:^(NSArray *placemarks, NSError *error) {
  CLPlacemark *placemark = [placemarks objectAtIndex:0];
  NSString *strCity = [placemark locality];
  NSLog(@"%@",strCity);
}];
