不兼容的指针类型将'id'发送到'SEL_Notnull'类型的参数

Question

[contactCell.no5 addTarget:self action:[self performSelector:@selector(numberEdit:cellIndex:) withObject:contactCell.no5 withObject:[NSNumber numberWithInteger:indexPath.row]] forControlEvents:UIControlEventValueChanged];

in contactCell.no5“no5 is textfield”和“contactCell is uitableviewcell object”...

1. 不兼容的指针类型将'id'发送到'SEL_Notnull'类型的参数
2. ARC不允许将Objective-C指针隐式转换为'SEL_Notnull'

功能 - ＆GT;

-(void)numberEdit:(UITextField *)textField cellIndex:(NSNumber *)row
{    
    [numberList removeObjectAtIndex:[row integerValue]];
    NSLog(@"%@",numberList.description);

    [numberList insertObject:textField.text atIndex:[row integerValue]];
    NSLog(@"%@",numberList.description);
}

Answer 1

试试这个

如果你有这样的文本字段：

UITextField *contactCell;

你需要添加targetLikeThis

 [contactCell addTarget:self action:@selector(numberEdit:cellIndex:) forControlEvents:UIControlEventValueChanged];

堡垒自定义行动：

-(void)numberEdit:(UITextField *)textField cellIndex:(NSNumber *)row
{    
    [numberList removeObjectAtIndex:[row integerValue]];
    NSLog(@"%@",numberList.description);

    [numberList insertObject:textField.text atIndex:[row integerValue]];
    NSLog(@"%@",numberList.description);
}
