使用多个条件过滤NSArray的NSDrary

Question

我使用以下代码过滤我的数组

NSArray *_filteredArray = [self.allData filteredArrayUsingPredicate:[NSPredicate predicateWithBlock:^BOOL(id evaluatedObject, NSDictionary *bindings) {
    NSDictionary *_dataRow = (NSDictionary *)evaluatedObject;
    return ([[[_dataRow valueForKey:@"name"] lowercaseString]  rangeOfString:[self.searchBar.text lowercaseString]].location != NSNotFound);
}]];

正如您在代码段中看到的，我只匹配@"name";如何检查第二个参数（例如@"city"）与我的过滤器匹配？

我尝试了allKeys和allValues，但都没有效果。

做这样的事情：

NSArray *_filteredArray = [self.allData filteredArrayUsingPredicate:[NSPredicate predicateWithBlock:^BOOL(id evaluatedObject, NSDictionary *bindings) {
NSDictionary *_dataRow = (NSDictionary *)evaluatedObject;
return ([[[_dataRow valueForKey:@"name"] lowercaseString]  rangeOfString:[self.searchBar.text lowercaseString]].location != NSNotFound) || ([[[_dataRow valueForKey:@"surname"] lowercaseString]  rangeOfString:[self.searchBar.text lowercaseString]].location != NSNotFound);
}]];
