從Plist中搜索

我有一個包含數組中的多個字典的Plist。從Plist中搜索

我無法從Plist中搜索。當我從下面的代碼搜索時，我只能搜索輸入完整名稱objectForKey:@"aName"，就像我需要輸入Sugar ..我無法使用sug..或s..I搜索將不得不打字糖，如果我搜索plist中的牛奶..它會顯示我的第一個字典，糖和plist顯示如下。我必須搜索以 objectForKey： @ 「aName」

從plist.please檢查那裏我得到錯誤的搜索...

「我無法從Plist中搜索」 - 確切地說？ – 2013-01-11 13:12:14

對我來說你的plist看起來像和數組，但你把它放到字典中... –

valueArray和mySection是數組 – Christien

它爲您提供的過濾NSArray，你可以用結果在做其他事情。如果你正在使用searchBar你應該使用它的委託方法

NSArray *_originalArray = ...; 
/* 
* EDITED : because the thread's owner has seriously no idea what it is. 
* 
* you can get the searchText's value from anywhere else of your code 
* (i.e. from UITextField, UISearchBar, and anywhere else...) 
* 
*/ 
NSString *searchText = ...; // EDITED : this is a parameter only, it can be set freely 
NSArray *_filteredArray = [originalArray filteredArrayUsingPredicate:[NSPredicate predicateWithBlock:^BOOL(id evaluatedObject, NSDictionary *bindings) { 
      NSDictionary *_dataRow = (NSDictionary *)evaluatedObject; 
      return ([[[_dataRow valueForKey:@"aName"] lowercaseString] rangeOfString:[searchText lowercaseString]].location != NSNotFound); 
     }]]; 

NSLog (@"%@", _filteredArray);

亞，但這上面的多個詞典plist不只是兩個...我不能去'糖'只有 – Christien

然後設置關鍵字自由...它可以設置爲任何如你看到的。 – holex

你沒有得到..我必須從密鑰@「aName」的plist搜索..和密鑰@「aName」將在數量爲100s ...我不必搜索任何特定的 – Christien

試試這個它可以幫助你......

，並從嘗試使用searchTableView方法..

爲如.. .try this

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


if([searchText length] > 0) { 
    searching = YES; 
    [self **searchTableView**:yourSearchBar]; ///give call to the **searchTableView** method.. 

    //show your search table.. 
} 

else { 
    searching = NO; 

    //set your search table hidden 
} 


} 



-(void)searchTableView:(UISearchBar *)searchBar { 

if (searchBar == yourSearchBar) { 
    NSString *searchText = yourSearchBar.text; 

    for (NSString *sTemp in yourValueArray) { 
     NSComparisonResult result = [sTemp compare:searchText options: (NSCaseInsensitiveSearch|NSDiacriticInsensitiveSearch) range:NSMakeRange(0, [searchText length])]; 

     if (result == NSOrderedSame) { 
      [self.yourTemporarySearchArray addObject:sTemp]; 


     } 
    } 

    [yourSearchTable reloadData]; 
} 

}
