I'm trying to insert Array of dictionary in CoreData using NSBatchInsertRequest according WWDC 2019 (https://developer.apple.com/videos/play/wwdc2019/230/). The insertResult is nil, and my CoreData is empty.

let modelURL = Bundle.main.url(forResource: "CoreDataPerformance", withExtension: "momd")!
let model = NSManagedObjectModel(contentsOf: modelURL)!
let container = NSPersistentCloudKitContainer(name: "CoreDataPerformance", managedObjectModel: model)
container.loadPersistentStores(completionHandler: { (storeDescription, error) in
    if let error = error as NSError? {
        fatalError("Unresolved error \(error), \(error.userInfo)")
    }
})

try container.viewContext.setQueryGenerationFrom(.current)

let moc = container.viewContext
moc.automaticallyMergesChangesFromParent = true
moc.perform {
    let insertRequest = NSBatchInsertRequest(entity: Client.entity(), …

我试图得到用户的事件.登录后我用以下代码询问用户ID:

[[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:nil]
 startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {

     NSLog(@"ID: %@", result[@"id"]);

     NSString *str = [NSString stringWithFormat:@"%@/events",result[@"id"]];

     FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc]
                                   initWithGraphPath:str
                                   parameters:nil
                                   HTTPMethod:@"GET"];
     [request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection,
                                           id result,
                                           NSError *error) {

         // Handle the result

     }];


 }];

结果是空的,虽然在图api资源管理器我得到数据!

谢谢

如何使用NSLog获取consol,UITextView上的gestureRecogniser列表？

这样的事情？

NSLog([UIGestureRecognizer description]);

这是我的主要内容:

int main(void)
{
    char w1[] = "Paris";
    ChangeTheWord(w1);
    printf("The new word is: %s",w1);
    return0;
}

我需要更改w1[]此函数的值:

ChangeTheWord(char *Str)
{

     ...

}
