你好朋友在我的一个活动中我创建了自定义文本字段，我有数组有50条记录并为加载数组记录创建自定义表....现在我想要当我们输入文本字段然后我的数组记录应该在表格视图中过滤并获得欲望记录...
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];
这是我的阵列......

） 此数据加载在自定义表中，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];
此表成功加载所有数据以及如何搜索所需名称使用自定义文本字段....请解决问题..

实施UITextFieldDelegate和方法
- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string;
在此方法中，当您在文本字段上书写时，可以搜索阵列中的文本并填充已过滤的数组。然后使用reloadData重新加载表。

试试这个::
[[NSNotificationCenter defaultCenter]
addObserver:self
selector:@selector(anyMethod:)
name:UITextFieldTextDidChangeNotification
object:textField1];
on change text Method（此处为“anyMethod：”）获取文本字段文本并获取与textfield文本匹配的记录并将其保存在另一个数组中。然后使用该筛选的数组加载数据。所以它看起来像tableview中的文本过滤器。
希望它能帮助!!

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。
希望这会对你有所帮助:)。

如果您使用搜索栏，请从表格数组创建临时数组。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];
}
