    <p>I use a single particle system for each type of effect. So, one for a fire effect, one for a sparkle, one for an explosion, etc.</p> <p>I use a category to add [enable] and [disable] methods to the base Cocos2D particle systems which looks like this:</p> <p>ParticleEnhancement.h</p> <pre><code>#include "cocos2d.h" @interface CCParticleSystem (particleEnhancement) -(void)enable; -(void)disable; @end </code></pre> <p>ParticleEnhancement.m</p> <pre><code>#import "ParticleEnhancement.h" @implementation CCParticleSystem (particleEnhancement) -(void)enable { active = YES; elapsed = 0.0f; } -(void)disable { active = NO; } @end </code></pre> <p>Then when I want to trigger it I just set the position and call enable. The particle system will spawn a bunch of particles based on the initialization settings. The system can be triggered multiple times in different positions and previously generated particles will behave properly.</p> <p>The main thing to consider is that you will need a larger particle budget to account for multiple instances of a given effect using a single system.</p> <p>Also, this works for "triggered" effects, like an explosion but may not work so well for a long running effect like a smoke trail, I haven't really tested that.</p> <p>I like doing it this way because it means I have fewer particle systems to wrangle and I don't have to deal with setting up a pool of particle systems. The particle system itself does a good job of handling a pool of particles, no need to replicate that again on the system level.</p> <p>This technique is being used in my app <a href="http://tcgcounter" rel="nofollow noreferrer">TCG Counter</a> for all of the particle effects.</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.
