为什么我无法获得此SQLite代码来为我的详细信息视图加载正确的数据? [英] Why can't I get this SQLite code to load the proper data for my detail view?

问题描述

- (void) hydrateDetailViewData {
//if detail view is hydrated then do not get it from database
if(isDetailViewHydrated) return;

if(detailStmt == nil) {
    const char *sql = "select snapTitle, snapDesc from Snap where snapID =?";
    if(sqlite3_prepare_v2(database, sql, -1, &detailStmt, NULL) != SQLITE_OK)
        NSAssert1(0, @"Error while creating detail view statement. '%s'", sqlite3_errmsg(database));
    NSLog(@"SQLite= %d", sqlite3_step(detailStmt)); 

}

if (sqlite3_step(detailStmt) == SQLITE_ROW)//execute sql statement on database, and make sure it executed properly.
{
    self.snapDescription = [NSString stringWithUTF8String:(char *)sqlite3_column_text(detailStmt, 1)];
}   

看着上面的代码，有人可以告诉我怎么了，为什么我无法将其加载到我的detailview上?我基本上遵循了iPhone sdk上的教程.不知道为什么会出错.

looking at the above code, can someone tell me what's wrong and why is it that i can't get it to load on my detailview?i basically followed the tutorial on iphone sdk article..but yet i am having this don't know why error.

如果你们需要看一下，我什至可以发送我的项目.

i can even send my project if u guys need to take a look.

错误消息:

 *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIViewController _loadViewFromNibNamed:bundle:] was unable to load a nib named "DetailView"'

推荐答案

您的错误和您的问题不匹配，就我所知，该错误与上述代码无关.

Your error and your problem don't match, the error is nothing to do with the above code as far as I can see.

错误与调用

The error is to do with a call to loadViewFromNibNamed:bundle: - I'm guessing that you don't have a xib file in your project called DetailView.xib
