如何删除[UITextField setPlaceSearchDelegate：]：这个错误？

Question

我正在使用此Library进行自动搜索位置

但我收到了错误

 Terminating app due to uncaught exception
 NSInvalidArgumentException', reason: -[UITextField setPlaceSearchDelegate:]: unrecognized selector sent to instance
 0x7faef34e1350'

任何人都可以解决这个错误的原因吗？

试过这段代码： -

#import "ViewController.h"
#import "MVPlaceSearchTextField.h"
#import "AppDelegate.h"
#import <GoogleMaps/GoogleMaps.h>
#import <GooglePlaces/GooglePlaces.h>
#import <GooglePlacePicker/GooglePlacePicker.h>
#import "RightSideViewController.h"
#import <MapKit/MapKit.h>
#import <CoreLocation/CoreLocation.h>
#import "SearchResultViewController.h"



@interface ViewController ()<PlaceSearchTextFieldDelegate,UITextFieldDelegate>
@property (weak, nonatomic) IBOutlet MVPlaceSearchTextField *txtPlaceSearch;

    _txtPlaceSearch.layer.cornerRadius = 50;


    locationManager = [[CLLocationManager alloc] init];
    [locationManager requestWhenInUseAuthorization];

    locationManager.desiredAccuracy = kCLLocationAccuracyBest;

    [locationManager startUpdatingLocation];
