目标c:使NSArray全部小写

这是我的建议

NSString *path = [[NSBundle mainBundle] pathForResource:@"kurdiebg" ofType:@"plist"];
NSArray *plistData = [NSArray arrayWithContentsOfFile:path];

NSPredicate *filter = [NSPredicate predicateWithFormat:@"english = %@", self.searchQwery.text];
NSArray *filtered = [plistData filteredArrayUsingPredicate:filter];



NSLog(@"found matches: %@ : %@", filtered,[filtered valueForKey:@"kurdi"]);

if (filtered.count>0) {
    NSDictionary *dic  = filtered[0];
    self.ss.text = dic[@"kurdi"];
}

修道院 (小写)它返回正确的结果,问题是它有20200条记录,它们不都是小写的,

A. 资本,它什么也不回报
