im trying build easy application view swiching , uiwebview worked till wrote uiwebview

-(ibaction)pushbutton {       termineviewcontroller *screen = [[termineviewcontroller alloc] initwithnibname:nil bundle:nil];      screen.modaltransitionstyle = uimodaltransitionstylecrossdissolve;      [self presentmodalviewcontroller:screen animated:yes]; thread 1: program receved signal: "sigabrt"     [screen release];  }  -(ibaction)pushbutton2 {      speiseplanviewcontroller *screen = [[speiseplanviewcontroller alloc] initwithnibname:nil bundle:nil];     screen.modaltransitionstyle = uimodaltransitionstylecrossdissolve;     [self presentmodalviewcontroller:screen animated:yes];     [screen release];     // //  termineviewcontroller.m //  lhappv3 // //  created joan on 03.07.11. //  copyright 2011 __mycompanyname__. rights reserved. //  #import "termineviewcontroller.h"   @implementation termineviewcontroller  -(ibaction)pushback {      [self dismissmodalviewcontrolleranimated:yes];  }  - (id)initwithnibname:(nsstring *)nibnameornil bundle:(nsbundle *)nibbundleornil {     self = [super initwithnibname:nibnameornil bundle:nibbundleornil];     if (self) {         // custom initialization     }     return self; }  - (void)dealloc {     [super dealloc]; }  - (void)didreceivememorywarning {     // releases view if doesn't have superview.     [super didreceivememorywarning];      // release cached data, images, etc aren't in use. }  #pragma mark - view lifecycle  /*   // implement viewdidload additional setup after loading view, typically nib.   - (void)viewdidload   {   [super viewdidload];   }   */   -(void)viewdidload {       [super viewdidload];      [webview loadrequest:[nsurlrequest requestwithurl:[nsurl urlwithstring:@"http://www.landheim-schondorf.de/news/"]]];      [nstimer scheduledtimerwithtimeinterval:1.0 target:self selector:@selector(checkload) userinfo:nil repeats:yes];      [nstimer scheduledtimerwithtimeinterval:1.0 target:self selector:@selector(checknotload) userinfo:nil repeats:yes];   }   -(void)checkload {       if(webview.loading) {          [active startanimating];       }   }   -(void)ckecknotload {       if(!(webview.loading)) {          [active stopanimating];       }   } - (bool)shouldautorotatetointerfaceorientation:(uiinterfaceorientation)interfaceorientation {     // return yes supported orientations     return (interfaceorientation == uiinterfaceorientationportrait); }  @end   // //  termineviewcontroller.h //  lhappv3 // //  created joan on 03.07.11. //  copyright 2011 __mycompanyname__. rights reserved. //  #import <uikit/uikit.h>   @interface termineviewcontroller : uiviewcontroller {      iboutlet uiwebview *webview;     iboutlet uiactivityindicatorview *active; }  -(ibaction)pushback;  @end

you not creating view.

-(void)viewdidload {      [super viewdidload];      webview = [[uiwebview alloc] initwithframe:arect]; //<--------     [webview loadrequest:[nsurlrequest requestwithurl:[nsurl urlwithstring:@"http://www.landheim-schondorf.de/news/"]]];      [nstimer scheduledtimerwithtimeinterval:1.0 target:self selector:@selector(checkload) userinfo:nil repeats:yes];      [nstimer scheduledtimerwithtimeinterval:1.0 target:self selector:@selector(checknotload) userinfo:nil repeats:yes];   }

additionally need release webview in dealloc. , should confortable properties.

edit
try catch bug of zombies: nszombieenabled
