如何为单个 UIButton 添加两个 UIButton 操作

Question

大家好，我正在尝试为单个 UIButton 添加两个不同的操作。在我看来，像“编辑”和“新建”这样的两个 UIButton 有不同的操作和一个表格视图。当我单击编辑按钮时，它显示表格视图的编辑选项，并且“新建”按钮标题标签更改为“清除”，“编辑”更改为“完成”，当我单击“清除”文本时，它将显示警报，单击取消按钮它会进入正常的先前状态。到目前为止，一切正常。如果我们单击“新建”，它应该导航到下一个视图，但我得到的是它显示的编辑选项并导航到下一个视图。

//编辑表格方法

- (void)setEditing:(BOOL)editing animated:(BOOL)animated
{
    [super setEditing:editing animated:animated];
    [messagesTableView setEditing:editing animated:YES];

}

//按钮动作和方法

    - (IBAction)editButtonAction:(id)sender
{
    if ([editButton.titleLabel.text isEqualToString:@"Edit"])
    {

        [self setEditing:YES];
        //
        [editButton setTitle:@"Done" forState:UIControlStateNormal];
        [editButton setTitle:@"Done" forState:UIControlStateSelected];

        [createNewMessageBtn setTitle:@"Clear" forState:UIControlStateNormal];
        [createNewMessageBtn setTitle:@"clear" forState:UIControlStateSelected];
        createNewMessageBtn.tag = 2;
        createNewMessageBtn.enabled = YES;
        createNewMessageBtn.userInteractionEnabled = YES;

        //        [self.voicemailTable reloadData];

    }
    else if ([editButton.titleLabel.text isEqualToString:@"Done"])
    {
        [self setEditing:NO];

        //
        [editButton setTitle:@"Edit" forState:UIControlStateNormal];
        [editButton setTitle:@"Edit" forState:UIControlStateSelected];

        [createNewMessageBtn setTitle:@"New" forState:UIControlStateNormal];
        [createNewMessageBtn setTitle:@"New" forState:UIControlStateSelected];
        createNewMessageBtn.tag = 1;
        createNewMessageBtn.enabled = YES;
        createNewMessageBtn.userInteractionEnabled = YES;
        //        [self.voicemailTable reloadData];

    }

    //
    [self.messagesTableView reloadData];

}

这个动作方法我试过了。提前谢谢

Answer 1

请尝试关注Code，在viewDidLoad 中关注Code

 [self.btnEdit setTitle:@"Edit" forState:UIControlStateNormal];
 [self.btnNew setTitle:@"New" forState:UIControlStateNormal];

现在您必须将Method 与您的Relevant UIButtons 联系起来

- (IBAction)btnEdit_Done_Click:(id)sender {

    if([[self.btnEdit titleForState:UIControlStateNormal] isEqualToString:@"Edit"]){
        NSLog(@"Put code for allow editing for TableView");
        [self.btnNew setTitle:@"Clear" forState:UIControlStateNormal];
        [self.btnEdit setTitle:@"Done" forState:UIControlStateNormal];
    }else{
        [self.btnEdit setTitle:@"Edit" forState:UIControlStateNormal];
        [self.btnNew setTitle:@"New" forState:UIControlStateNormal];
    }

}

- (IBAction)btnNew_Clear_Click:(id)sender {

    if([[self.btnNew titleForState:UIControlStateNormal]isEqualToString:@"New"]){
        NSLog(@"Push to New Controller");
    }else{
        UIAlertView * alert = [[UIAlertView alloc]initWithTitle:@"Title" message:@"Message" delegate:self cancelButtonTitle:nil otherButtonTitles:@"Ok",@"Cancel", nil];
        [alert setTag:101];
        [alert show];
    }
}

-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {

    if([alertView tag] == 101){

        [self.btnEdit setTitle:@"Edit" forState:UIControlStateNormal];
        [self.btnNew setTitle:@"New" forState:UIControlStateNormal];
        if(buttonIndex == 1){
            NSLog(@"clear All Thing");
        }else{
            NSLog(@"No Action");
        }
    }
}

Answer 2

在标签值的基础上，你可以像下面这样添加：-

(editButton.tag==1) ? [editButton addTarget:self action:@selector(doEditAction:) 
forControlEvents:UIControlEventTouchUpInside]:[editButton addTarget:self action:@selector(doneAction:) forControlEvents:UIControlEventTouchUpInside];

-(void)doEditAction:(id)sender
{

}
-(void)doneAction:(id)sender
{

}

Answer 3

据我了解，

首先将 addTarget as 'newbtnaction' 设置为按钮“New”，然后在该方法中将按钮标题更改为“clear”，并将 addtarget 设置为 'clearaction' 方法名称。

与第二个按钮相同。
