你好朋友在我的一项活动中，我创建了自定义文本字段，并且我有一个包含 50 条记录的数组，并为加载数组记录创建了自定义表....现在我想要当我们输入文本字段时，我的数组记录应该被过滤和在表格视图中获取欲望记录...

UITextField *patientname=[[UITextField alloc]initWithFrame:CGRectMake(130,10,170,30)];
patientname.font = [UIFont boldSystemFontOfSize:15.0];
patientname.tag=1;
//the horizontal alignment of the text
patientname.textAlignment = NSTextAlignmentLeft;
patientname.borderStyle = UITextBorderStyleBezel;
patientname.contentVerticalAlignment = UIControlContentHorizontalAlignmentCenter;
patientname.clearButtonMode = UITextFieldViewModeWhileEditing; 
patientname.delegate =self;
[Self.view addSubview:patientname];

这是我的数组...

) 此数据加载到自定义表中，如 ....

 table_SearchPatient=[[UITableView alloc]initWithFrame:CGRectMake(130,40,170,250)style:UITableViewStylePlain];
table_SearchPatient.delegate=self;
table_SearchPatient.dataSource=self;
table_SearchPatient.layer.borderWidth = 2.0;
table_SearchPatient.layer.borderColor = [UIColor grayColor].CGColor;
[self.view addSubview:table_SearchPatient];

该表成功加载所有数据以及如何使用自定义文本字段搜索所需名称..请解决问题..

实现 UITextFieldDelegate 和方法

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string;

在这种方法中，当您在文本字段上书写时，您可以在数组中搜索文本并填充过滤后的数组。然后你用 reloadData 重新加载你的表。

首先，您必须添加观察者以获取文本更改通知。

[[NSNotificationCenter defaultCenter] 
            addObserver:self 
               selector:@selector(textFieldDidChangeText:)
                   name:UITextFieldTextDidChangeNotification 
                 object:textField];

然后实现给定的文本更改通知方法，

-(void)textFieldDidChangeText:(id)sender {

NSString *text = [sender text];

tableViewDataSrcArray = [dataSrcArray filterUsingPredicate:[NSPredicate predicateWithFormat:@"SELF contains[cd] %@", text]];
[tableView reloadData];
}

假设“dataSrcArray”是您的实际列表，“tableViewDataSrcArray”是您的表视图数据源数组。

希望对你有帮助 ：）

如果您使用搜索栏，请从表数组创建一个临时数组。并使用以下方法

-(void)searchBar:(UISearchBar*)searchBar textDidChange:(NSString*)text
{
    if(text.length == 0)
    {
        isFiltered = FALSE;
        tableDataArray  = tempArray;
    }
    else
    {
        isFiltered = TRUE;
        NSMutableArray *searchArray = [NSMutableArray arrayWithArray:friendsArray];
        NSPredicate *predicate  = [NSPredicate predicateWithFormat:@"name contains[c] %@",text];
        tableDataArray  =[NSMutableArray arrayWithArray:[searchArray filteredArrayUsingPredicate:predicate]];

    }

    [self.tableView reloadData];
    [searchBar becomeFirstResponder];

}

试试这个方法::

[[NSNotificationCenter defaultCenter] 
                addObserver:self 
                   selector:@selector(anyMethod:)
                       name:UITextFieldTextDidChangeNotification 
                     object:textField1];

更改文本方法（此处为“anyMethod：”）获取文本字段文本并获取与文本字段文本匹配的记录并将其保存在另一个数组中。然后使用该过滤后的数组加载数据。使它看起来像表格视图中的文本过滤器。

希望能帮助到你！！
