CATransition is an Objective-C wrapper for creating view transitions. As of 3.1.2, there are 11 types of transitions. 4 of them are SDK-compatible, but are the most boring ones. The following shows all 11 types of transition from picture "A" to "B" at 40%. The subtypes, if any, is "fromLeft".

Subtype and filter
Many transitions have are further divided into several discrete subtypes. They often control the movement direction of the animation.
Some transitions accept addition arguments through the filter property, for example, you can set the location of suckEffect using
...
CAFilter* filter = [CAFilter filterWithName:@"suckEffect"];
[filter setValue:[NSValue valueWithCGPoint:CGPointMake(160, 240)] forKey:@"inputPosition"];
transition.filter = filter;
...
