Question

我整天都在尝试，但搜索显示委托方法的方法不起作用。

我有一个加载plist的tableview，我正在尝试实现搜索功能。

这是我的代码

#import "TabelViewController.h"
#import "Cell.h"
 @interface TabelViewController ()

@property (nonatomic,copy) NSDictionary *names;
@property (nonatomic,copy) NSArray *keys;
@property (nonatomic,copy) NSArray *FIOArray;
@property (nonatomic,copy) NSMutableArray *filtredNames;
@property (nonatomic,copy) UISearchDisplayController *searchController;

@end

剂量正常工作的方法。我不知道如何从我的plist中正确加载字典来实现搜索

  -(BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString{

[filtredNames removeAllObjects];

if (searchString.length > 0) {

    NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF contains [search] %@", self.searchBar.text];


    for (NSString *key in keys ){

        NSArray *matches = [names[key]  filteredArrayUsingPredicate:predicate];


        [filtredNames addObjectsFromArray:matches];

    }

     }
    return YES;
 }

Plist结构

<plist version="1.0">
          <dict>
<key>А</key>
<array>
    <dict>
        <key>ФИО</key>
        <string>Аетров А.В.</string>
        <key>Доклад</key>
        <string>Доклад 5</string>
        <key>Время</key>
        <string>10:00-10:30</string>
        <key>День</key>
        <string>Четверг</string>
    </dict>
</array>

此代码会将您的plist加载到字典中：

NSString * filePath = [[NSBundle mainBundle] pathForResource:@"Your_actual_file_name" ofType:@"plist"];
names = [NSDictionary dictionaryWithContentsOfFile:filePath];
NSMutableArray * allValues = [NSMutableArray new];

for (NSArray * array in dict.allValues) {
    [allValues addObjectsFromArray:array];
}

FIOArray = allValues;

然后您的搜索方法将如下所示：

-(BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString{

 [filtredNames removeAllObjects];

 if (searchString.length > 0) {

    NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF contains [search] %@", searchString];
    NSArray *matches = [FIOArray filteredArrayUsingPredicate:predicate];

    [filtredNames addObjectsFromArray:matches];

   }
 return YES;
 }

如何在字典plist中实现字符串的搜索？
