   int iWeight;
 }

end

Test.m

@implementation Test

- (void)viewDidLoad

   iWeight = 15; 
}

    **NSLog(@"integer Number is :%@", iWeight);  // error occur**

}

If i click the Button of UIAlertView, Xcode occur "EXC_BAD_ACCESS" error at that code

I don't know why that code occur error. help me.

回答1:

Try NSLog(@"integer Number is :%d", iWeight);

回答2:

yes, try this

NSLog(@"wieght is %d",iweight);

%d type specifier for int iweight;

and also set property in .h file and synthesize it in .m file.

if it dont work then try this
remove your alertview method

write this


// .h file
-(IBAction)buttonClicked; 

// .m file
-(IBAction)buttonClicked
{
   NSLog(@"weight %d",iweight");
}

right click of button and assign TouchUpInside to buttonClicked method.
