导入头文件

#import "ChineseInclude.h"
#import "PinYinForObjc.h"

    NSMutableArray *searchResults;//可变数组，添加搜索到的数据

设置数据源

- (NSArray *)dataArray {
    if (!_dataArray) {
        _dataArray = @[@"百度",@"六六",@"谷歌",@"苹果",@"and",@"table",@"view",@"and",@"and",@"苹果IOS",@"谷歌android",@"微软",@"微软WP",@"table",@"table",@"table",@"六六",@"六六",@"六六",@"table",@"table",@"table"];
    }
    return _dataArray;
}

监听textField

   [_textField addTarget:self action:@selector(textFieldEditChanged:) forControlEvents:UIControlEventEditingChanged];

当输入的时候进行搜索

- (void)textFieldEditChanged:(UITextField *)mySearchBar
{
    searchResults = [[NSMutableArray alloc]init];
    if (mySearchBar.text.length>0&&![ChineseInclude isIncludeChineseInString:mySearchBar.text]) {
        for (int i=0; i<self.dataArray.count; i++) {
            if ([ChineseInclude isIncludeChineseInString:self.dataArray[i]]) {
                NSString *tempPinYinStr = [PinYinForObjc chineseConvertToPinYin:self.dataArray[i]];
                NSRange titleResult=[tempPinYinStr rangeOfString:mySearchBar.text options:NSCaseInsensitiveSearch];
                if (titleResult.length>0) {
                    [searchResults addObject:self.dataArray[i]];
                }
                
//                NSString *tempPinYinHeadStr = [PinYinForObjc chineseConvertToPinYinHead:self.dataArray[i]];
//                NSRange titleHeadResult=[tempPinYinHeadStr rangeOfString:mySearchBar.text options:NSCaseInsensitiveSearch];
//                if (titleHeadResult.length>0) {
//                    [searchResults addObject:self.dataArray[i]];
//                }
            }
            else {
                NSRange titleResult=[self.dataArray[i] rangeOfString:mySearchBar.text options:NSCaseInsensitiveSearch];
                if (titleResult.length>0) {
                    [searchResults addObject:self.dataArray[i]];
                }
            }
        }
    } else if (mySearchBar.text.length>0&&[ChineseInclude isIncludeChineseInString:mySearchBar.text]) {
        for (NSString *tempStr in self.dataArray) {
            NSRange titleResult=[tempStr rangeOfString:mySearchBar.text options:NSCaseInsensitiveSearch];
            if (titleResult.length>0) {
                [searchResults addObject:tempStr];
            }
        }
    }
    NSLog(@"搜索结果：%@",searchResults);
　　　　//在这里刷新
  　　// [_tableView reloadData];
}
