无法点击一个UIButton这是对视图的右上方推后下一个视图

Question

我有这样的

由tableview中的视图和一个UIButton当我点击“添加”一个名为“Locsetting”的新班级/ xib应该打开，但我无法做到。 我的代码：.h文件中

@interface LocationViewController : UIViewController  <UITableViewDelegate,UITableViewDataSource>  
{ 
    UITableView *table;  
    NSMutableArray *menuList; 
    LocSetting *locSetting; 
    IBOutlet UIButton *addbutton; 
} 

@property (nonatomic,retain) NSMutableArray *menuList; 
@property (nonatomic,retain) IBOutlet UITableView *table; 
@property (nonatomic,retain) LocSetting *locSetting; 
@property (nonatomic, retain) IBOutlet UIButton *addbutton; 
-(IBAction)gotoLocSetting:(id) sender; 
@end 

    My .m :  

@synthesize addbutton; 
-(IBAction)gotoLocSetting:(id) sender { 
    NSLog(@"gotoLocSetting Entered"); 
    locSetting = [[LocSetting alloc] 
        initWithNibName:@"LocSetting" 
        bundle:nil]; 
    //locationViewController.menuList = [menuList objectAtIndex:indexPath.row]; 
    [self.navigationController pushViewController:locSetting 
             animated:YES]; 
    [locSetting release]; 

} 

我在做什么错误或请指导我？！ 感谢

Answer 1

确保IBAction为正确连接到按钮。我认为最好有IBOutlet UIButton *addbutton;单独和@property (nonatomic, retain) UIButton *addbutton;

Answer 2

在快看，有可能是以下3个问题之一：

1. 是您的IBAction为链接到该按钮的出路何在？

2. 如果不是，请尝试删除LocSetting *locSetting;及其属性/合成。接下来，那里更改行：Locsetting *locSetting = [[LocSetting alloc] initWithNibName:@"LocSetting" bundle:nil];

3. 如果还是不行，请尝试更改，为：Locsetting *locSetting = [[LocSetting alloc] initWithNibName:nil bundle:nil];
