标题: ios - NSCFNumber getCString maxLength编码在创建地理围栏时出错

当我尝试将半径添加到围栏应用程序时,出现[__NSCFNumber getCString:maxLength:encoding:]崩溃。
这是我的代码:

NSString *identifier = [dictionary valueForKey"id"];

CLLocationDegrees latitude = [[dictionary valueForKey"lat"] doubleValue];

CLLocationDegrees longitude =[[dictionary valueForKey"lon"] doubleValue];

CLLocationCoordinate2D centerCoordinate = CLLocationCoordinate2DMake(latitude, longitude);

CLLocationDistance regionRadius = [[dictionary valueForKey"radius"] doubleValue];
NSLog(@"nslog is %f",regionRadius);


if(regionRadius > _locationManager.maximumRegionMonitoringDistance)
{
    regionRadius = _locationManager.maximumRegionMonitoringDistance;
}

NSString *version = [[UIDevice currentDevice] systemVersion];
CLRegion * region =nil;

if([version floatValue] >= 7.0f) // for iOS > 7
{
    region =  [[CLCircularRegion alloc] initWithCenter:centerCoordinate
                                                radius:regionRadius
                                            identifier:identifier];
}
else // for iOS < 7
{
    region = [[CLRegion alloc] initCircularRegionWithCenter:centerCoordinate
                                                     radius:regionRadius
                                                 identifier:identifier];
}

这里的Stacktrace是

试试这个

NSString * identifier = [[字典valueForKey“id”] stringvalue];
