ios - exception in NSArrayM insertObject:atindex -

i have used 4 images in project ..while running results in:

* terminating app due uncaught exception 'nsinvalidargumentexception', reason: '* -[__nsarraym insertobject:atindex:]: object cannot nil' *** first throw call stack:

my code :

nsarray *imagenames= @[@"jake_2.png",@"jake_3.png",@"jake_4.png",@"jake_5.png "]; // additional setup after loading view, typically nib. nsmutablearray *images = [[nsmutablearray alloc] init]; (int = 0; < imagenames.count; i++) {     [images addobject:[uiimage imagenamed:[imagenames objectatindex:i]]];     uiimageview *slowanimationimageview = [[uiimageview alloc] initwithframe:cgrectmake(160, 95, 86, 193)];     slowanimationimageview.animationimages = images;     slowanimationimageview.animationduration = 5;     [self.view addsubview:slowanimationimageview];     [slowanimationimageview startanimating]; } 

you're facing issue because imagename provided in array not available in resources. check last object in array : @"jake_5.png ". there's space in it. please remove it. thats causing issue.

update :

for animation, need set after images added in imagearray. refer code , make changes :

nsmutablearray *images = [[nsmutablearray alloc] init]; (int = 0; < imagenames.count; i++) {     [images addobject:[uiimage imagenamed:[imagenames objectatindex:i]]]; }  slowanimationimageview.animationimages = images; slowanimationimageview.animationduration = 5; [slowanimationimageview startanimating];  

hope helps...
