1、筛选纯字符串数组的内容

NSArray *array = [[NSArray alloc]initWithObjects:@"beijing",@"shanghai",@"guangzou",@"wuhan", nil];NSString *string = @"ang";NSPredicate *pred = [NSPredicate predicateWithFormat:@"SELF CONTAINS %@",string];NSLog(@"%@",[array filteredArrayUsingPredicate:pred]);

 输出结果是：

(    shanghai,    guangzou)
