Xcode中的“ EXC_BAD_ACCESS”

Question

在运行iPhone模拟时，我在Xcode中显示“ EXC_BAD_ACCESS”的错误

代码如下：

测试

 @interface Test : UIViewController
 {
   int iWeight;
 }

end

测试

@implementation Test

- (void)viewDidLoad 
{
   iWeight = 15; 
}

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{

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

}

如果我单击UIAlertView的按钮，则Xcode会在该代码处发生“ EXC_BAD_ACCESS”错误

我不知道为什么该代码会发生错误。 帮我。

Answer 1

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

Answer 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.
