ios - 从 Plist 搜索

Question

有人能帮我吗

我在应用程序启动我的应用程序时加载了 plist 并且我有一个搜索输入。当我在输入中插入文本时，我想从 plist

中搜索

self.plistFile = [[NSBundle mainBundle] pathForResource:[NSString stringWithFormat:@"xutbe"] ofType:@"plist"];
self.allData = [NSArray arrayWithContentsOfFile:self.plistFile];

我这样试过但是不行

NSString *INPUT = @"s";
self.plistFile = [[NSBundle mainBundle] pathForResource:[NSString stringWithFormat:@"filename"] ofType:@"plist"];
self.allData = [NSArray arrayWithContentsOfFile:self.plistFile];

NSArray *searchRes = [self.allData filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:@"self == %@", INPUT]];
NSLog(@"%@", searchRes);

也试过了，还是不行

NSString* plistPath = [[NSBundle mainBundle] pathForResource:@"xutbe" ofType:@"plist"]; NSDictionary* dict = [NSDictionary dictionaryWithContentsOfFile:plistPath]; NSDictionary* vcDict = [dict valueForKey:@"sd"]; NSLog(@"%@", vcDict);

如果你想从 NSArray 中搜索一个对象，使用 NSPredicate

NSArray *searchRes = [self.allData filteredArrayUsingPredicate:[NSPredicate
   predicateWithFormat:@"self == %@", INPUT]];
