iphone - How i solve memory leak problem? -

i developing simple application in design or make code in creating , instance object of uiimage. when swip on ipad screen make image of sreen , image render uiimage object after image set uiimageview object , uiimage object released. every time swipe on screen , above process again , again. give me leak in renderimage = [[uiimage alloc] init];.

code,

_renderimage = [[uiimage alloc] init];  _textimagev = [[uiimageview alloc] init];  [self renderintoimage];  -(void)renderintoimage {      uigraphicsbeginimagecontext(bgtableview.bounds.size);     [self.view.layer renderincontext:uigraphicsgetcurrentcontext()];     _renderimage = uigraphicsgetimagefromcurrentimagecontext();     uigraphicsendimagecontext(); }   _textimagev.image = _renderimage; [_renderimage release]; 

after completing process of swipe releasing _textimagev.

how solve memory leak problem in uiimage *_renderimage?

on line:

_renderimage = uigraphicsgetimagefromcurrentimagecontext(); 

uigraphicsgetimagefromcurrentimagecontext() returns new autoreleased uiimage , points _renderimage ivar it. allocated uiimage never released, variable repointed somewhere else.

this abandoned uiimage causes/is memory leak. should either release before pointing _renderimage else, or not allocate in first place.
