How does the "German map SDK" achieve smooth movement of the trajectory?

A lot of people should have similar experience, call the car, want to see how far away from me? But the mobile phone screen of the car is not motionless, is a jump in the drift.

At present, most of the products on the market "trajectory smooth movement" do not do well.

On the market only a quick taxi and a car to achieve a smooth move, then this is how to do it?

• Using interfaces

/* */-(void) Addtrackinganimationforpoints: (Nsarray *) points Duration: ( Cftimeinterval) duration;

Where the trace point type is:

@interface Tracingpoint:nsobject /*  */@property (nonatomic) cllocationcoordinate2d coordinate; /*  */@property (nonatomic) Cllocationdirection course; @end
