Question

我对Xcode和Parse有点新，并且我在outlet集合中创建了一个查询。一切看起来都不错，除了我收到一条错误，指出“属性'文字'在'id'类型的对象上找不到”...这是我的代码：

[query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
    if (!error) {
        // The find succeeded.
        NSLog(@"Successfully retrieved %d scores.", objects.count);
        // Do something with the found objects
        int i = 0;
        for (PFObject *object in objects) {
            if (i >= [self.EventTitles count]) break;//to make sure we only write up to the max number of UILabels available in EventTitles
            (UILabel *) self.EventTitles[i].text = object.objectId;//I assume the "objectId" property of object is an NSString!
            i++;
        }
    } else {
        // Log details of the failure
        NSLog(@"Error: %@ %@", error, [error userInfo]);
    }
}];

任何人都可以帮助我，所以我可以让这个版本不失败吗？

改变这个：

(UILabel *) self.EventTitles[i].text = object.objectId;

为：

[(UILabel *)self.EventTitles[i] setText:object.objectId];

在对象上找不到属性文本
