You can use the CGRectContainsPoint() method. This method will return a boolean value. You need to pass the views frame(CGRect) and the coordinates relative to touch(CGPoint).

https://developer.apple.com/library/mac/#documentation/graphicsimaging/reference/CGGeometry/Reference/reference.html#//apple_ref/c/func/CGRectContainsPoint

Also you can check with this method too,

CGPoint aPoint = //your touch point;
BOOL isPointInsideView = [yourView pointInside:aPoint withEvent:nil];

Here the given point (aPoint) is checked with the view you are giving (yourView) and returns a boolean value.
