i have code , when executes, throws nullreferenceexception , saying: object reference not set instance of object. what mean, , can fix error? what cause? bottom line you trying use null (or nothing in vb.net). means either set null , or never set @ all. like else, null gets passed around. if null in method "a", method "b" passed null to method "a". the rest of article goes more detail , shows mistakes many programmers make can lead nullreferenceexception . more specifically the runtime throwing nullreferenceexception always means same thing: trying use reference, , reference not initialized (or once initialized, no longer initialized). this means reference null , , cannot access members (such methods) through null reference. simplest case: string foo = null; foo.toupper(); this throw nullreferenceexception @ second line because can't call instance method toupper() on string reference pointing null .

for creating login page or that, in autolayout case use tableview instead of using scrollview in viewcontroller. indexpath majority cases reuse customcell. entirely different items use customcell. since cell class increasing in project. dont know practice. please share opinion increase overall performance , least memory usage application. putting uitableview in views not practice every time. recommend using scrollviews , content views inside them in pages login. use tableviews in screens show repeated contents. have seen codes generated through tableview controllers in every page. dont in way. better go scrollviews.. method far have seen.
