Question

Basically what I am trying to figure out, is how to write the following:

//pseudo-code
if (the x value for contentOffset is equal to 
   a figure between, say, 50 and 100) {
   then a specific void is to be executed. 
} 

Thanks!

Answer 1

CGPoint offsetPoint = myScrollView.contentOffset;
float offset = sqrtf(powf(offsetPoint.x,2)+(powf(offsetPoint.y,2));
if (50 < offset && offset < 100) {
   [self myMethod];
}

or if you are only interested in one direction, say vertically,

CGFloat offset = myScrollView.contentOffset.y;
