Best Practices

Development

• use an iPhone 4 or 4s or an iPad 2 for development; the iPhone 3Gs is only supported for compatibility purposes and not suited for development

Management of Points of Interest

• the performance of the AR component scales with the number of objects managed by it (more objects -> AR slower)
• use blocks and background queues to add a lot of markers simultaneously
• the iPhone 4s and iPad 2 can handle a huge number of POIs (we successfully tested 100+ POIs with good performance)
• you need to scale back the number of markers on iPhone 4 and iPhone 3Gs
