标题: ios - 如何获取所有在解析中注册的用户..在ios中使用PFInstallation

我正在使用下面的代码来获取用户，但我无法获取它.. 应用程序崩溃了...请帮助我获取所有安装对象列表..

PFQuery *userQuery = [PFQuery queryWithClassName"_Installation"];
[userQuery findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
    if (!error) {
        // The find succeeded.
        NSLog(@"Successfully retrieved %d scores.", objects.count);
        NSLog(@"objc...%@",objects);
        // Do something with the found objects
        for (PFObject *object in objects) {
            NSLog(@"id...%@",object.objectId);
        }
    } else {
        // Log details of the failure
        NSLog(@"Error: %@ %@", error, [error userInfo]);
    }
}];

Best Answer-推荐答案

试试这个:

PFQuery *userQuery = [PFInstallation query];
[userQuery findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
    if (!error) {
        // The find succeeded.
        NSLog(@"Successfully retrieved %d scores.", objects.count);
        NSLog(@"objc...%@",objects);
        // Do something with the found objects
        for (PFObject *object in objects) {
            NSLog(@"id...%@",object.objectId);
        }
    } else {
        // Log details of the failure
        NSLog(@"Error: %@ %@", error, [error userInfo]);
    }
}];

仅供引用，Wain 的评论是正确的，即安装不是用户。您确定这是您要查询的类(class)吗？
