这是头文件......

#import <UIKit/UIKit.h>

@interface sideTableViewController : UIViewController <UITableViewDelegate, UITableViewDataSource>
{
    NSArray *colorNames;
}
@property (strong, nonatomic) IBOutlet UITableView *sideTableView;
-(IBAction)showMessage;
@property (nonatomic, retain) NSArray *colorNames;

@end

我正在尝试将图像作为现有tableview的背景。我得到一个例外：[sideTableViewController tableView：numberOfRowsInSection：]：无法识别的选择器发送到实例0x7593640

请帮助我成为IOS编程的新手！
