Question

我是iOS新手，我遇到了从数组中获取字符串当前值的问题。

我的代码就像这样

loginStatusHS = [[NSString alloc] initWithBytes: [myNSMDatalatetudeFromServer mutableBytes] length:[myNSMDatalatetudeFromServer length] encoding:NSUTF8StringEncoding];
    NSLog(@"loginStatus =%@",loginStatusHS);
    NSError *parseError = nil;
    NSDictionary *xmlDictionary = [XMLReader dictionaryForXMLString:loginStatusHS error:&parseError];
    NSLog(@"JSON DICTIONARY = %@",xmlDictionary);
    recordResultHS = [xmlDictionary[@"success"] integerValue];
    NSLog(@"Success: %ld",(long)recordResultHS);
    NSDictionary* Address=[xmlDictionary objectForKey:@"soap:Envelope"];
    NSLog(@"Address Dict = %@",Address);
    NSDictionary *new =[Address objectForKey:@"soap:Body"];
    NSLog(@"NEW DICT =%@",new);
    NSDictionary *LoginResponse=[new objectForKey:@"HS_GetResponse"];
    NSLog(@"Login Response DICT =%@",LoginResponse);
    NSDictionary *LoginResult=[LoginResponse objectForKey:@"HS_GetResult"];
    NSLog(@"Login Result =%@",LoginResult);
    if(LoginResult.count>0)
    {
        NSLog(@"Login Result = %@",LoginResult);
        NSLog(@"Login Result Dict =%@",LoginResult);
        NSString *teststr =[[NSString alloc] init];
        teststr =[LoginResult objectForKey:@"text"];
        NSLog(@"Test String Value =%@",teststr);
        NSString *string = [LoginResult valueForKey:@"text"];
        NSData *data = [string dataUsingEncoding:NSUTF8StringEncoding];
        responseletetudedict = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil];
        NSLog(@"Latetude Dictionary =%@",responseletetudedict);
        idlatetudearray=[[NSMutableArray alloc]init];
        idlatetudearray=[responseletetudedict valueForKey:@"City"];

        NameHSArray=[[NSMutableArray alloc] init];
        NameHSArray=[responseletetudedict valueForKey:@"Name"];
        AddressHSArray=[[NSMutableArray alloc] init];
        AddressHSArray=[responseletetudedict valueForKey:@"Address"];
        FacilitiesHSArray=[[NSMutableArray alloc] init];
        FacilitiesHSArray=[responseletetudedict valueForKey:@"Facilities"];
        PhoneNoHSArray=[[NSMutableArray alloc] init];
        PhoneNoHSArray=[responseletetudedict valueForKey:@"Phoneno"];
        FaxnoHSArray=[[NSMutableArray alloc] init];
        FaxnoHSArray=[responseletetudedict valueForKey:@"Faxno"];
        LatitudeHSArray=[[NSMutableArray alloc] init];
        LatitudeHSArray=[responseletetudedict valueForKey:@"Latitude"];
        LongitudeHSArray=[[NSMutableArray alloc] init];
        LongitudeHSArray=[responseletetudedict valueForKey:@"Longitude"];
        TypeHSArray=[[NSMutableArray alloc] init];
        TypeHSArray=[responseletetudedict valueForKey:@"Type"];

        for (int i=0; i<NameHSArray.count; i++) {
            double LatitudeDouble = [LatitudeHSArray[i] doubleValue];
            double LongitudeDouble = [LongitudeHSArray[i] doubleValue];
            CLLocationCoordinate2D position = CLLocationCoordinate2DMake(LatitudeDouble, LongitudeDouble);
            GMSMarker *marker = [GMSMarker markerWithPosition:position];
            marker.title = NameHSArray[i];
            marker.snippet=AddressHSArray[i];
            userData = [[NSArray alloc] initWithObjects:NameHSArray[i], AddressHSArray[i],FacilitiesHSArray[i], PhoneNoHSArray[i],FaxnoHSArray[i], TypeHSArray[i], nil];
            marker.userData = userData;

            if([TypeHSArray[i] isEqualToString:@"ESIC"])
            {
                marker.icon = [UIImage imageNamed:@"mapicon2.png"];
            }
            else
            {
                marker.icon = [UIImage imageNamed:@"mapicon1.png"];
            }
            GMSCameraUpdate *zoomCamera = [GMSCameraUpdate zoomIn];
            [mapView animateWithCameraUpdate:zoomCamera];

            marker.map = mapView;

        }

当我点击诺贝尔医院时加入图片我给代表打电话

  - (void)mapView:(GMSMapView *)mapView didTapInfoWindowOfMarker:(GMSMarker *)marker {
    // your click action

    StringAddress =  marker.snippet;
    StringName = marker.title;

    NSLog(@"Address=%@",StringAddress);
    NSLog(@"Name= %@",StringName);

    lblNamepopup.text=StringName;
    lblAddresspopup.text=StringAddress;

    NSLog(@"User Data Array = %@",userData);

    viewpopup.hidden=NO;
    viewpopup.transform = CGAffineTransformMakeScale(0.01, 0.01);
    [UIView animateWithDuration:0.2 delay:0 options:UIViewAnimationOptionCurveEaseOut animations:^{
        viewpopup.transform = CGAffineTransformIdentity;
    } completion:^(BOOL finished){
        // do something once the animation finishes, put it here
    }];
}

在这个委托中听到我需要获取字符串地址的当前名称。但是听到我收到Last值意味着字符串得到覆盖。如何获取从数组中单击的值。在此先感谢！

您可以获得索引

Try below query :

SELECT MONTH(f.Created_Date), f.Created_By_User_ID
FROM Fees f 
WHERE EXISTS(SELECT 1 FROM [User] u WHERE f.Created_By_User_ID= u.User_ID 
AND DATEDIFF(DAY,f.Created_Date,'2016-01-01') <= 0 AND
    DATEDIFF(DAY,f.Created_Date,'2016-12-31') >= 0

您也可以使用

我从图书馆找到了一些参考资料。
请注意，userData不应包含对任何地图的强引用
对象，否则可能会创建一个循环（阻止ARC释放对象）。

注意： - 您可以通过代码段传递数据，但将代码段显示数据传递到信息窗口。这样您就可以创建自定义信息窗口并根据需要显示数据。
像这样，

-(void)mapView:(GMSMapView *)mapView didTapInfoWindowOfMarker:(GMSMarker *)marker
{
    NSInteger index = [NameHSArray indexOfObject:marker.title];
    NSLog(@"%ld",(long)index);
}

retrive
像这样，

NSArray * userData = [NSArray alloc] initWithObjects:FacilitiesHSArray[i], PhoneNoHSArray[i],FaxnoHSArray[i], nil];
NSString *userDataString = [userData componentsJoinedByString:@";"];
marker.snippet = userDataString;

你可以这样做

 NSString *userDataString = marker.snippet;
 NSArray *array = [userDataString componentsSeparatedByString:@";"];
 NSLog(@"%@",array);
