    <p>I'm doing some porting from Qt Cocos2d to iOS cocos2d, am using Objective-C++ as the language for minimal efforts, now I'm wrapping the NSMutableArray in a C++ class for easier porting, basically this is my class</p> <p>QList.h</p> <pre><code>#ifndef QLIST_H #define QLIST_H #import &lt;Foundation/Foundation.h&gt; class QList { NSMutableArray* List; public: QList(); ~QList(); void append(id); id at (int i); int size(); bool isEmpty(); id takeLast(); id last(); void prepend(id); id takeAt(int i); id takeFirst(); void clear(); }; #endif </code></pre> <p>QList.mm</p> <pre><code>#ifndef QLIST_MM #define QLIST_MM #import "QList.h" QList::QList() { List = [[NSMutableArray alloc] init]; } QList::~QList() { [List autorelease]; List = nil; } void QList::append(id object) { [List addObject:object]; } id QList::at(int i) { return [List objectAtIndex:i]; } int QList::size() { return [List count]; } bool QList::isEmpty() { if ([List count] == 0) return true; return false; } id QList::takeLast() { id temp = [List lastObject]; [List removeLastObject]; return temp; } id QList::last() { return [List lastObject]; } void QList::prepend(id object) { [List insertObject:object atIndex:0]; } id QList::takeAt(int i) { id temp = [List objectAtIndex:i]; [List removeObjectAtIndex:i]; return temp; } id QList::takeFirst() { return takeAt(0); } void QList::clear() { [List removeAllObjects]; } #endif </code></pre> <p>I'm recieving EXC_BAD_SIGNAL on this line</p> <pre><code> return [List count]; </code></pre> <p>Could anyone help me, I much appreciate it, thanks in advance :)</p>

    1. COThere's no problem with this, the problem was in this line ai_unit.playerP = this; I was commenting it out until a later time so I can uncomment it, and it was trying to access that :) Thanks!, if you have advice for this code, let me know :P

    2. COAdvice/Warning: Make sure you code does not implicitly copy a `QList` object or you might end up over releasing `List` with out a call to retain in the copy constructor.

    3. COThank you for the advice, Actually also I have removed the code in the destructor method ~QList because it's causing problems, and added a function called release which after using any QList, I release it manually

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.
