NSDictionary中NSArray的NSPredicate

Question

数组：

(
   {id:1,data:(@"macbook",@"mac mini")},
   {id:2,data:(@"ipad",@"ipod")},
   {id:3,data:(@"macbook",@"ipod")}
)

predicate：

NSString *text = @"mac";
[NSPredicate predicateWithFormat:@"(data contains[cd] %@)",text];
[array filteredArrayUsingPredicate:predicate];

但是没有再dictionary中实现循环数组。

不知道应该怎么解决，请指教。

Answer 1

NSString* text = @"mac" ;
NSPredicate* predicate = [NSPredicate predicateWithFormat:@"any data contains[cd] %@",text] ;
NSArray* filteredArray = [theArray filteredArrayUsingPredicate:predicate] ;
