Question

我使用下面的代码搜索地点并获取我在api（https://maps.googleapis.com/maps/api/place/queryautocomplete/json?input=%@&key=My_Key）下面使用的地点列表。它工作正常，但每次搜索只显示两个位置。但是GMSAutoCompleteViewController为每次搜索显示两个以上的位置。如何为每次搜索获得两个以上的位置，如GMSAutoCompleteVC。

#import "ViewController.h"
#import <GooglePlaces/GooglePlaces.h>

@interface ViewController () <UITextFieldDelegate, UITableViewDelegate, UITableViewDataSource> {

    NSMutableArray *searchArray;
    NSString *strSearch;

}

@property (weak, nonatomic) IBOutlet UITextField *searchTextfeild;
@property (weak, nonatomic) IBOutlet UITableView *tbl_vw1;

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.  

    _searchTextfeild.delegate = self;
    _tbl_vw1.delegate = self;
    _tbl_vw1.dataSource = self;
    _tbl_vw1.hidden = YES;

    _searchTextfeild.clearButtonMode = UITextFieldViewModeAlways;

}

    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.

    // This API key is from https://developers.google.com/maps/web/
    NSString *str1 = [NSString stringWithFormat:@"https://maps.googleapis.com/maps/api/place/queryautocomplete/json?input=%@&key= My_Key", strSearch];

我改变了我的代码......

我得到的地方超过两个，但是我使用了json count [jsondic.allKeys count]

for(int i=0;i<[jsondic.allKeys count];i++)
    {
        NSString *str1=[[[jsondic objectForKey:@"predictions"] objectAtIndex:i] objectForKey:@"description"];
        [searchArray  addObject:str1];
    }

现在我只有两个地方

现在我将json计数从[jsondic.allKeys count]更改为[[jsondic objectForKey：@“predictions”] count]

for(int i=0;i<[[jsondic objectForKey:@"predictions"] count];i++)
    {
        NSString *str1=[[[jsondic objectForKey:@"predictions"] objectAtIndex:i] objectForKey:@"description"];
            [searchArray  addObject:str1];
    }

现在我有两个以上的地方......
