如何添加位置不仅仅是NSString而且还有纬度和经度,所以它在日历中也显示了一个地图？

<EKCalendarItem>  

https://developer.apple.com/LIBRARY/ios/documentation/EventKit/Reference/EKCalendarItemClassRef/index.html#//apple_ref/occ/instp/EKCalendarItem/location

@property(nonatomic, copy) NSString *location;

代码:

 EKEventStore *store = [[EKEventStore alloc] init];
[store requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error) {
    if (!granted) { return; }
    EKEvent *event = [EKEvent eventWithEventStore:store];
    event.title = @"Event Title";
    event.startDate = [NSDate date]; //today
    event.endDate = [event.startDate dateByAddingTimeInterval:60*60];  //set 1 hour meeting
    event.notes=@"Note";
    event.location=@"Eiffel Tower,Paris"; //how do i add Lat & long / CLLocation?
    event.URL=[NSURL  URLWithString:shareUrl];
    [event setCalendar:[store defaultCalendarForNewEvents]];
    NSError *err = nil;
    [store saveEvent:event span:EKSpanThisEvent commit:YES error:&err];
    NSString *savedEventId = event.eventIdentifier;  //this is …

我使用gridview显示数字,所以如果我点击任何数字,下一个活动应该开始.我尝试了这段代码,但应用程序崩溃了

         private GridView gridView = null;

      gridView.setOnClickListener(new OnClickListener()

    {
              public void onClick(View v5) 

        {
            setContentView(R.layout.Abc);
            Intent myIntent = new 

 Intent(getApplicationContext(),Abc.class);
            startActivity(myIntent);

        }
    });

这是gridview的xml代码

     <GridView
    android:id="@+id/month_gridView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_below="@+id/calendar_days"
    android:layout_marginLeft="7dp"
    android:layout_marginRight="8dp"
    android:background="@color/grid_background"
    android:fadingEdge="none"
    android:gravity="top|left"
    android:horizontalSpacing="2dp"
    android:listSelector="@android:color/transparent"
    android:numColumns="7"
    android:padding="1dp"
    android:stretchMode="columnWidth"
    android:verticalSpacing="2dp">
</GridView>

我想\ ,,/在Java中显示 为字符串,但我得到无效的转义序列.

尝试了所有可能的方法

   String Metal= "'\'"+",,/";

   Toast a= Toast.makeText(getApplicationContext(), Metal, Toast.LENGTH_LONG);
   a.show();

   String Metal= "\"+",,/";

得出结论 ",,/

我怎样才能做到这一点？
