所有这些错误都是什么？

Question

#import <UIKit/UIKit.h>


@interface ProfileViewController : UIViewController {
    UIImageView *profPic;
    UILabel *name;
    UILabel *hosted;
    UILabel *points;
    UILabel *attended:
    UITableView *tableView;
}

@property (nonatomic, retain) IBOutlet UIImageView profPic;
@property (nonatomic, retain) IBOutlet UILabel name;
@property (nonatomic, retain) IBOutlet UILabel hosted;
@property (nonatomic, retain) IBOutlet UILabel points;
@property (nonatomic, retain) IBOutlet UILabel attended:
@property (nonatomic, retain) IBOutlet UITableView tableView;

@end

Answer 1

虽然您尚未公布错误，但您的代码中存在两个明显的问题：

1. 行尾的冒号应该是分号：

   @property (nonatomic, retain) IBOutlet UILabel attended:
                                                         ^^^
   

2. 属性类型应该是指针（在属性声明中忽略'*'）

   @property (nonatomic, retain) IBOutlet UILabel* attended;
   

Answer 2

那些UI *对象应该是指针：

IBOutlet UIImageView * profPic;

Answer 3

@property (nonatomic, retain) IBOutlet UIImageView *profPic;

在对象名称前添加星号（*）。
