调试代码，并检查执行或不委托方法？如果它没有执行，那么你不会执行搜索栏协议@interface ViewController（） – Janmenjaya 2014-10-28 09:57:50

@Chetan Gharat你得到了什么错误？ – 2014-10-28 11:51:41

试试这个

searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0.0, 0.0, 320.0, 41.0)]; 
    [self.view addSubview:searchBar]; 
    searchBar.delegate=self; 

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { 

    // Return the number of sections. 
    return 1; 
} 

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { 
    // Return the number of rows in the section. 
    if (isSearching) { 
     return [filteredContentList count]; 
    } 
    else { 
     return [titlearray count]; 
    } 
} 
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { 
    // Return YES for supported orientations 
    return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown); 
} 
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
    static NSString *simpleTableIdentifier = @"SimpleTableCell"; 

    SimpleTableCell *cell = (SimpleTableCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier]; 
    if (cell == nil) 
    { 
     NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"SimpleTableCell" owner:self options:nil]; 
     cell = [nib objectAtIndex:0]; 
    } 
    if (isSearching) 
    { 
     cell.nameLabel.text = [filteredContentList objectAtIndex:indexPath.row]; 
     cell.thumbnailImageView.image =[filteredImgArray objectAtIndex:indexPath.row]; 
    } 
    else 
    { 
     cell.thumbnailImageView.image = [imagearray objectAtIndex:indexPath.row]; 
     cell.nameLabel.text = [titlearray objectAtIndex:indexPath.row]; 
    } 
    return cell; 
} 
- (void)searchTableList { 
    NSString *searchString = searchBar.text; 

    for (int i=0; i<titlearray.count; i++) { 
     NSString *tempStr=[titlearray objectAtIndex:i]; 
     NSComparisonResult result = [tempStr compare:searchString options:(NSCaseInsensitiveSearch|NSDiacriticInsensitiveSearch) range:NSMakeRange(0, [searchString length])]; 
     if (result == NSOrderedSame) 
     { 
      [filteredContentList addObject:tempStr]; 
      [filteredImgArray addObject:[imagearray objectAtIndex:i]]; 
     } 
    } 

} 

#pragma mark - Search Implementation 

- (void)searchBarTextDidBeginEditing:(UISearchBar *)searchBar { 
    isSearching = YES; 
} 

- (void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText { 
    NSLog(@"Text change - %d",isSearching); 

    //Remove all objects first. 
    [filteredContentList removeAllObjects]; 
    [filteredImgArray removeAllObjects]; 

    if([searchText length] != 0) { 
     isSearching = YES; 
     [self searchTableList]; 
     //tblContentList.hidden=NO; 
    } 
    else { 
     isSearching = NO; 
     // tblContentList.hidden=YES; 
    } 
    [tblContentList reloadData]; 
} 

- (void)searchBarCancelButtonClicked:(UISearchBar *)searchBar { 
    NSLog(@"Cancel clicked"); 
} 

- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar { 
    NSLog(@"Search Clicked"); 
    [self searchTableList]; 
}

我希望它对你有帮助

我会检查这2maro和接受你的答案感谢兄弟帮助 – 2014-10-28 14:29:12

其工作谢谢 – 2014-10-29 04:26:34

@ChetanGharat美好的一天 – 2014-10-29 04:30:01

它

SmsTitle *title = [array objectAtIndex:indexPath.row];

所以，你永远不能摆脱filteredContentList数据：因为你总是用这个作为数据源不起作用。

你需要做的就是保持参照主要的UITableView的属性，并使用这种方法来获得PROPERT的NSArray在所有UITableViewDataSource委托方法数据来源：

- (NSArray*) dataSourceForTableView:(UITableView*) tableView 
{ 
    return tableView == self.tableView ? self.array : self.filteredContentList; 
}

我已经实施 – 2014-10-28 10:01:17

是的，但有什么问题给我的解决方案 – 2014-10-28 10:01:54

没有它的不工作 – 2014-10-28 10:08:17

查看加载

allItem = [[NSArray alloc] initWithObjects:@"One",@"Two",@"Three",@"Four",@"Five",@"Six", nil]; 

displayItem = [[NSMutableArray alloc] initWithArray:allItem];

增加这个搜索栏方法只

-(void)searchBar:(UISearchBar *) searchBar textDidChange:(NSString *)searchText 

{ 
if ([searchText length] == 0) 
{ 
    [displayItem removeAllObjects]; 
    [displayItem addObjectsFromArray:allItem]; 
} 
else 
{ 
    [displayItem removeAllObjects]; 

    for (NSString *string in allItem) 
    { 
     NSRange r = [string rangeOfString:searchText options:NSCaseInsensitiveSearch]; 

     if (r.location != NSNotFound) 
     { 
      [displayItem addObject:string]; 
     } 
    } 

} 
[tableViewObj reloadData];

}

-(void)searchBarSearchButtonClicked:(UISearchBar *)searchBar 
{ 
[searchBar resignFirstResponder];}
