对于搜索下拉表,我需要分别在单元格文本标签和详细文本标签中显示“描述”和“搜索条款”。我需要实现基于两个字符串的过滤器,即搜索文本应该与“Description”和“SearchTerms”进行比较。我试过 NSPredicate 但它只能过滤一个字符串
NSString *substring = [NSString stringWithString:searchServiceTextField.text];
NSLog(@"substring %@",substring);
NSMutableArray *arr2Filt= [searchArray valueForKey:@"Description"];
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF contains[c] %@",substring];
NSArray *filteredarr = [NSMutableArray arrayWithArray:[arr2Filt filteredArrayUsingPredicate:predicate]];
NSLog(@"filtered array %@",filteredarr);
我尝试修改两个字符串,但没有得到更好的解决方案。
[{
Description = "Rental Jewellery, Jewellery for events";
ProfessionId = "<null>";
SKUFormat = "<null>";
SearchTerms = "Rental Jewellery";
SpecialityId = 62;
tokens = "<null>";
value = "<null>";
},
{
Description = "Kids Party with Food and Games Venues";
ProfessionId = "<null>";
SKUFormat = "<null>";
SearchTerms = "Party Venue";
SpecialityId = 63;
tokens = "<null>";
value = "<null>";
},
{
Description = "Music, Dance, Sports classes";
ProfessionId = "<null>";
SKUFormat = "<null>";
SearchTerms = Classes;
SpecialityId = 64;
tokens = "<null>";
value = "<null>";
},
{
Description = "Zumba, Yoga, Aerobics classes";
ProfessionId = "<null>";
SKUFormat = "<null>";
SearchTerms = "Fitness/Health";
SpecialityId = 65;
tokens = "<null>";
value = "<null>";
}
]
最佳答案
你可以这样做
NSString *substring = [NSString stringWithString:searchServiceTextField.text];
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"Description contains[c] %@ AND SearchTerms contains[c] %@",substring, substring];
NSArray * filteredarr =[[searchArray filteredArrayUsingPredicate:predicate] copy];
NSLog(@"filtered array %@",filteredarr);
