Google 搜索地点 API 只找到 2 个地点？

Question

我使用下面的代码搜索地点并获取我在下面使用的地点列表 api (https://maps.googleapis.com/maps/api/place/queryautocomplete/json?input=%@&key=My_Key)。它工作正常，但在每次搜索中只显示两个位置。但是 GMSAutoCompleteViewController 为每次搜索显示了两个以上的位置。如何为 GMSAutoCompleteVC 等每次搜索获取两个以上的位置。

#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;

}

    NSString *str1 = [NSString stringWithFormat:@"https://maps.googleapis.com/maps/api/place/queryautocomplete/json?input=%@&key= My_Key", strSearch];
    NSURL *url = [NSURL URLWithString:str1];

Answer 1

我这样修改了我的代码...

我得到了两个以上的名额，但我用了 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];
    }

现在我只有两个名额

现在我将 json count 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];
    }

现在我得到了两个以上的名额.....
