Question

I am having a major problem with my iPhone app. My problem seems basic but I cannot find out the reason for the error. I have a NSString saveDescription that is set by user’s input.

 savede = civilsJobDescTb.text;

I then call in a NSLog to check the string has been set, and it is. So I have no problem there.

Later in the program I create a PDF file with several details. Everything works ok except the NSString that I have set earlier. It seem as if the string no longer exists. I get an error from it. EXC_BAD_ACCESS or something like that.

Now for the weird thing. This only happens when I have a whitespace in the text box. Eg: I enter “ok” and it will work without problem. But if I enter “Everything is ok” then I get errors.

I can’t see where the problem is. Any ideas?

You didn’t specify if your “savede” is an ivar (instance variable) but assuming that it is,

and if you are using ARC, set a strong property to it:

@property (nonatomic, strong) NSString * savede;

self.savede = civilsJobDescTb.text;

If you are not using ARC, then make sure to retain your “savede” string after setting it. Something like:

 savede = civilsJobDescTb.text;
 [savede retain];

(making sure to release it when you are truly finished with it).

You can also make a copy of the string (in case the label that it’s coming from disappears, or is cleared, or somehow disappears).

[savede setString: civilsJobDescTb.text];
[savde retain];
