2.注意点

需导入头文件
#import <CoreLocation/CoreLocation.h>//定位

3.代码展示

//地理编码
@property(nonatomic,strong) CLGeocoder *geocoder;

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    //创建地址解析器
    self.geocoder = [[CLGeocoder alloc]init];
    
}
//正向解析
- (IBAction)jiexi:(id)sender {
    //获取输入地址信息
    NSString *addre = self.address.text;

4.还有欠妥，请多多指教。
