    <p>I have a class that manages the database queries for my project and I'm having some issues with memory management and the <code>[return autorelease]</code>part of the code. I don't know how to return an object to the calling function but it uses it afterwards. The code is this:</p> <pre><code>-(Hexagram *)getHexagramforId:(NSInteger)hexagramNumber{ Hexagram *current; if (init_statement == nil) { const char * sql = "SELECT * FROM HEXNUMBER where _id =?"; if (sqlite3_prepare_v2(database, sql, -1, &amp;init_statement, NULL) != SQLITE_OK) { NSAssert1(0, @"Error:failed to prepare argument with message %s", sqlite3_errmsg(database)); } sqlite3_bind_int(init_statement, 1, hexagramNumber); if (sqlite3_step(init_statement) == SQLITE_ROW) { current = [[Hexagram alloc]initWithId:hexagramNumber Title:[NSString stringWithUTF8String:(char*)sqlite3_column_text(init_statement, HEX_TITLE)] LongText:[NSString stringWithUTF8String:(char*)sqlite3_column_text(init_statement, HEX_TEXT)]ShortText:nil InternalColor:sqlite3_column_int(init_statement, INTERNAL_COLOR) ExternalColor:sqlite3_column_int(init_statement, EXTERNAL_COLOR)]; }else{ NSAssert1(0, @"Database is corrupt, error %s", sqlite3_errmsg(database)); } sqlite3_reset(init_statement); sqlite3_close(database); init_statement = nil; return current; } return nil; </code></pre> <p>}</p> <p>So what happens is in the analyzer it says that the object current hexagram is leaked, but if I return it with an autorelease it crashes. I want to support iOS &lt; 5 so I don't want to use ARC but so far I don't know how to return this object and not get this error in the static analyzer. Any help please?</p>

    1. COAre you using ARC in present code?

    2. CONote, you **can** use ARC below iOS 5, but you don't have weak pointers available to you, you only have unsafe_unretained available for non strong types.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
