    <p>I'm developing an application with adobe air 3 for ios and having low memory errors frequently. After ios 5 update os started to kill my app after some low memory warnings.</p> <p>But the thing is profiler says app uses 4 to 9 megs of memory. There are a lot of bitmap copy operations around and sometimes instantiates new bitmaps from embedded bitmaps. I highly optimized everything and look for leaks etc.</p> <p>I watch profiler for memory status and seems like GC clears everything. everything looks perfect but app continues to get low memory errors and gets killed by os.</p> <p>Is there anything wrong with this code below. Because my assumption is this ClassReference never gets off from memory even the profiles says memory is cleared. I used clone method to pass value instead of pass by ref. so I guess GC can collect that local variable. I tried with and without clone nothing changes.</p> <p>If the code below runs 10-15 times with different tile Id's app crashes but with same ID's it continues working.</p> <p>Is there anyone who is familiar with this kind of thing?</p> <p>tmp is bitmapData</p> <pre><code>if (isMoving) { tmp=getProxyImage(x,y); //low resolution tile image } else { strTmp="main_TILE"+getTileID(x,y); var ClassReference:Class = getDefinitionByName(strTmp) as Class; //full resolution tile image //something wrong here tmp=new ClassReference().bitmapData.clone(); //something wrong here ClassReference=null; } return tmp.clone(); </code></pre> <p>Thanks for reading. I hope some one has a solution for this.</p>

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.
