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];

在contactCell.no5中“no5是文本字段”和“contactCell是uitableviewcell对象”...

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-->

-(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];

堡垒自定义动作：

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

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