ios - NSPredicate面临的问题

Question

在下面的词典中，我有一个字典列表，我试图根据谓词获得相同的值，但我没有得到该值。

    NSPredicate* searchPredicate = [NSPredicate predicateWithFormat:@"(%K CONTAINS[c] %@)",@"**equipArray.equipmentName**",textField.text];

    NSLog(@"searchPredicate %@",searchPredicate);

    NSArray* searchList = [list filteredArrayUsingPredicate:searchPredicate];

但我无法得到名单。谁能帮我 ？

    {
    equipArray =         (
                    {
            equipmentIcon = "outside.png";
            equipmentName = Outside;
        },
                    {
            equipmentIcon = "steps.png";
            equipmentName = Steps;
        },
                    {
            equipmentIcon = "partner.png";
            equipmentName = Partner;
        }
    );
    exId = 4;
    exeName = "Fireman Carry";
    exerciseAudioCue = "DG Fighting Fit-exercise_audio_test.mp3";
    exerciseDescription = "Proin gravida nibh vel velit auctor aliquet. Aenean sollicitudin, lorem quis bibendum auctor, nisi elit consequat ipsum, nec sagittis sem nibh id elit. Duis sed odio sit amet nibh vulputate cursus a sit amet mauris. Morbi accumsan ipsum velit. Nam nec tellus a odio tincidunt auctor a ornare odio.

    exerciseType = Stamina;
    imageThumbNail = "firemancarry_thumbnail.png";
    longVideoName = long;
    shortVideoName = small;
}

Answer 1

如果要查找equipmentName中任何equipArray包含以下内容的元素，
给定的字符串，使用:

[NSPredicate predicateWithFormat:@"ANY %K CONTAINS[c] %@", @"equipArray.equipmentName", textField.text];

(“CONTAINS”用于字符串比较，而不是检查数组中是否包含。)
