ios - Scrollview come back on same position in up and down direction whenever leave scrolling -


i using uiscrollview , set it's content size same view's height.

i need make scrollview scrolls same in both side (up / down).

it come in same position mean whenever scrolls in top direction , leave scrolling come y = 20 pixels when scroll in bottom direction come on 20 pixels when leave scrolling...

for setting scrollview content size 

 cgsize scrollviewcontentsize = cgsizemake(self.view.frame.size.width, self.view.frame.size.height); [self.scrollviewbg setcontentsize:scrollviewcontentsize];

also have tried give content offset 

 [scrollviewbg setcontentoffset:cgpointmake(0, 0) animated:yes];

but not solved problem.

i updated , make scrollview's height similar view's height , increase it's content height , solved problem. 

-(void)viewdidappear:(bool)animated{  float space = 2.5; // making scroll view scrolls , on same positions both sides.  cgsize scrollviewcontentsize = cgsizemake(self.view.frame.size.width, self.view.frame.size.height+space); [self.scrollviewbg setcontentsize:scrollviewcontentsize]; [scrollviewbg setcontentoffset:cgpointmake(0, 0) animated:yes];

}

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
