Ios 正在获取-[\uu NSArrayI integerValue]异常

2015-07-13 23:56:13.659 ICBus[41867:12770881]-[\uu NSArrayI intValue]：发送到实例0x7fddc8e00e30的无法识别的选择器 2015-07-13 23:56:13.670 ICBus[41867:12770881]*由于未捕获的异常“NSInvalidArgumentException”而终止应用程序，原因：'-[\uu NSArrayI intValue]：未识别的选择器发送到实例0x7fddc8e00e30' *第一次抛出调用堆栈：

他是我解析到一个类中的数据，然后从那里我使用这些数据在我的地图上显示一辆公共汽车的GPS位置。我不相信我在数组上调用intvalue。我将数据分离为NSString，然后为busGPS实例化我的类。然后在类的实例上，我对该类的属性调用intValue。请帮忙，谢谢你。他提供了公交车位置的数据： { 标题=-4； id=110； lat=41.66044； 液化天然气=-91.53468； }

我需要的lat和液化天然气在int格式使用谷歌地图api。这是我的密码。 这是我的模型对象 标题：

界面：

#import "BusLocation.h"

@implementation BusLocation

- (instancetype) initWithLat:(NSString *)lat lng:(NSString *)lng heading:(NSString *)heading {

    self = [super init];

    if (self) {
        _lat = lat;
        _lng = lng;
        _heading = heading;

    }
    return self;
}

@end

他是我地图视图的标题

#import <UIKit/UIKit.h>
#import "MapViewController.h"
#import "API.h"
@class BusLocation;

@interface MapViewController : UIViewController

@property (strong, nonatomic) NSString *routeAgency;

@property int testLatInt;
@property int testLngInt;
@property (strong, nonatomic) NSString *testLng;

用完整准确的错误更新您的问题。添加一个异常断点以标识异常发生的行。此外，获取纬度的intValue没有多大意义-纬度是十进制数。请显示NSLog@Bus位置：%@，self.busLocation；
