Iphone 如何修改NSMutableArray属性？

我使用2个sqlite db文件

1） 从sqlite数据库填充项目

@property (nonatomic, strong) NSMutableArray *items;  

FMDatabase *userDB = [FMDatabase databaseWithPath:userfmdbPath];  
NSString *query2 = [NSString stringWithFormat:@"SELECT zidx, highlight_YN FROM zHighlight where zbook = %d and zchapter = %d order by zidx ", pBook,pChapter];

FMResultSet *userresults = [userDB executeQuery:query2]; 

FMResultSet *results = [db1 executeQuery:query];

    while ([results next]) {

        Book *book = [[Book alloc] init];

        book.content = [results stringForColumn:@"Zcontent"];
        book.title   = [results stringForColumn:@"Ztitle"];
        book.idx     = [results intForColumn:@"Zidx"];

        book.highlight_YN  = NO;

        [items addObject:book];
        [book release];
    }

2） 然后，从other-B-sqlite数据库中选择项

@property (nonatomic, strong) NSMutableArray *items;  

FMDatabase *userDB = [FMDatabase databaseWithPath:userfmdbPath];  
NSString *query2 = [NSString stringWithFormat:@"SELECT zidx, highlight_YN FROM zHighlight where zbook = %d and zchapter = %d order by zidx ", pBook,pChapter];

FMResultSet *userresults = [userDB executeQuery:query2]; 

3） 问题：我想修改结果为

userresults

的项目的属性（

highlight_YN

），与

results

-

zidx

相比

如何修改

NSMutableArray

属性

您可以通过

项

数组循环搜索对象

    for ( Book *book in items ) {
        if( book.idx == [userresults intForColumn:@"zidx"] )
        {
            book.highlight_YN = [userresults boolForColumn:@"highlight_YN"];
            break;
        }
    }

我在上面的代码中没有看到NSMutableArray。事实上，我看到了各种各样的问题（比如

[items addObject:bible]

中的

圣经从哪里来？）。请修改您的问题以清理您的代码，并引入一个NSMutableArray。@Michael Dautermann抱歉！我遗漏了一些代码。谢谢我的问题经过编辑^^*
