POCIFilter works when built for 32-bit, but doesn't appear when built for 64-bit?

    <p>I have an XCode project that I originally set up to build to either 32 or 64 bit. Part of the code creates a layer with a border, and then adds a "bloom" filter to create a glowing effect around the border:</p> <pre><code>// Create a layer with just a border CGColorRef yellowColour = CGColorCreateGenericRGB(1.0f, 1.0f, 0.0f, 1.0f); CALayer *selectionLayer = [CALayer layer]; selectionLayer.bounds = CGRectMake(0.0f, 0.0f, size.width, size.height); selectionLayer.borderWidth = 3.0f; selectionLayer.borderColor = yellowColour; selectionLayer.position = CGPointMake(100, 50); selectionLayer.zPosition = CGFLOAT_MAX; // stay on top // Add a bloom filter to add a glow to the border CIFilter *filter = [CIFilter filterWithName:@"CIBloom"]; [filter setDefaults]; [filter setValue:[NSNumber numberWithFloat:5.0f] forKey:@"inputRadius"]; [selectionLayer setFilters:[NSArray arrayWithObject:filter]]; </code></pre> <p>When I build this project as a 32-bit app, the layer appears, and the yellow border correctly has the glowing effect applied. </p> <p>If I then build and run in 64-bit, the layer does not appear at all (i've tried changing the background colour to make sure the layer is visible)</p> <p>If I comment out the line that adds the filter, the layer reappears with its yellow border (but with no filter applied to it).</p> <p>As soon as I switch back to 32-bit again, it all works fine.</p> <p>What am I missing here? Do I need to change frameworks or change some other build flag so that the filter will work in 64-bit mode? </p>

    1. CONot gonna solve the problem, but you appear to be leaking `yellowColour`.

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.
