Question

我的aryContacts包含test_tech，test，abc_tech，testing，hh_techvedika

 NSArray *arrSeperated = [[[aryContacts objectAtIndex:i]valueForKey:@"contactName"]componentsSeparatedByString:@“_”];
    NSPredicate *predicate =[NSPredicate predicateWithFormat:@"contactName CONTAINS [cd]%@",[arrSeperated objectAtIndex:0]];
         NSArray    *arrContacts1 = [aryContacts filteredArrayUsingPredicate:predicate];

    NSPredicate *predicate1 =[NSPredicate predicateWithFormat:@"contactName CONTAINS [cd]%@",[arrSeperated objectAtIndex:1]];
            NSArray    *arrContacts2 = [aryContacts filteredArrayUsingPredicate:predicate1];

结果：arrContacts1包含test_tech，test，testing 预期：arrContacts1包含test_tech，test

结果：arrContacts2包含test_tech，abc_tech，hh_techvedika 预期：arrContacts2包含test_tech，abc_tech

Answer 1

尝试以下代码

NSPredicate *predicate = [NSPredicate predicateWithFormat:@"contactName BEGINSWITH [cd]%@", [[arrTempContacts objectAtIndex:i] valueForKey:@"contactName"]];
NSArray *arrContacts = [arrTempContacts filteredArrayUsingPredicate:predicate];

让我知道它是否有效!!!!

快乐的编码!!!

使用NSPredicate进行字符串比较
