[UIImage retain]: message sent to deallocated instance - objective-c

Question

We created button in the init method and we created two Uiimage objects and created Boolean
if(!isHint)
{
[hintBtn setImage:hintBtnImage forState:UIControlStateNormal];
}
else
{
[hintBtn setImage:hintBtnImagex forState:UIControlStateNormal];
}
hintBtn =[[UIButton alloc]initWithFrame:CGRectMake(794, 144, hintBtnImage.size.width, hintBtnImage.size.height)];
[hintBtn setImage:hintBtnImage forState:UIControlStateNormal];
[hintBtn addTarget:self action:#selector(showHint) forControlEvents:UIControlEventTouchUpInside];
When ever user taps the tableview cell we changes the boolean variable and we set the image .like the below code
if(wrongx==1)
{
NSLog(#"the wrong x is %i",wrongx);
isHint = NO;
[hintBtn setImage:hintBtnImage forState:UIControlStateNormal];
}
But when i tap the application first time it is working but second time i am getting the below error
[UIImage retain]: message sent to deallocated instance
Plz reply to my post.Thanks in advance

Answer 1

where you allocated "hintBtnImage" object.I think your trying to access the "hintBtnImage" withoout allocating.
hintBtn =[[UIButton alloc]initWithFrame:CGRectMake(794, 144, hintBtnImage.size.width, hintBtnImage.size.height)];
small code modification needed ,its not related to solve your problem,above line should be like this
hintBtn =[[UIButton alloc]initWithFrame:CGRectMake(794, 144, hintBtnImage.size.width, hintBtnImage.size.height)];
if(!isHint)
{
[hintBtn setImage:hintBtnImage forState:UIControlStateNormal];
}
else
{
[hintBtn setImage:hintBtnImagex forState:UIControlStateNormal];
}
