ios - NSPredicate完全匹配

Question

 NSArray *arrData = [NSArray arrayWithObjects:
                    @"cloud,country,plant",
                    @"country,cloud,plant",
                    @"country,plant,cloud",
                    @"clouds,country,plant"
                    ,@"country,clouds,plant",
                    nil];

从NSArray上方，我希望对象具有单词“cloud”

我尝试下面的代码

NSPredicate *predicate = [NSPredicate predicateWithFormat:@"(self beginswith %@ OR self contains[CD] %@)",@"cloud",@",cloud"];
NSArray *arrResult = [arrData filteredArrayUsingPredicate:predicate];

但是它在arrResult中提供了所有5个对象。但是我只需要3(0,1,2)个对象。

尝试:

 NSPredicate* predicate = [NSPredicate predicateWithBlock:^(NSString* string, NSDictionary* options){

    NSArray* array = [string componentsSeparatedByString:@","];

    return [array containsObject:@"cloud"];

}];
