Question

iPhone app development: Sudden flood of _NSAutoreleaseNoPool errors, why??

Asked by: ehensens

Hi everyone,

I have an iPhone app and I recently added some code that, quite simply, created some NSStrings, defined them with stringWithFormat from some c++ char[]'s I had already, and set the titles of some UILabels as these NSStrings. I've done this before without any problems. The application compiles without any errors or warnings, and it runs like it should, but I am getting a HUGE flood of _NSAutoreleaseNoPool errors in the console! I don't understand them. I'm posting both the code I added as well as the errors on the console window.

Can anyone tell me what the heck is going on here and how to fix it? Please let me know if you have any questions. Thanks in advance!!

NSString *iImageSizeAsNS = [NSString stringWithFormat:@"Size: %.1f KB", ((float)iImageSize / 1024)];
	NSString *cImageTitleAsNS = [NSString stringWithFormat:@"%s", cImageTitle];
	NSString *cFileNameAsNS = [NSString stringWithFormat:@"%s", cFileName];
	NSString *ImageDimensionsAsNS = [NSString stringWithFormat:@"Dimensions: %d x %d", iImageWidth, iImageHeight];
	
	ImageSizeLabel.text = iImageSizeAsNS;
	ImageTitleLabel.text = cImageTitleAsNS;
	FileNameLabel.text = cFileNameAsNS;
	ImageDimensionsLabel.text = ImageDimensionsAsNS;

hi ehensens,

Look up 'initWithFormat:'



-isdi-

 

by: isdiPosted on 2009-06-16 at 10:42:43ID: 24640383

Again, look up initWithFormat. The answer is there.

I know it works because I took your code sample, dropped it in a function and compiled it to get the errors you received.

Then I replaced what I needed to replace (all of ten seconds) and it compiled fine.

Hi isdi,

Would you care to mention what you did so quickly to fix the issue?

 

by: ehensensPosted on 2009-06-16 at 10:46:08ID: 24640421

Are you simply saying use "initWithFormat" instead of "stringWithFormat"?

 

by: isdiPosted on 2009-06-16 at 13:54:23ID: 24642467

Hello,

Yes. That was intent. Normally I explain whatever is required and/or post source when I answer a question. However, in this case, I felt it was more important to know the difference between initWithFormat and stringWithFormat.

In the API reference, the descriptions are only several sentences long.  When I initially posted the first response, the expectation was that the time would be taken to read the brief description of initWithFormat and then try it.

However, I am glad that the solution was tried and the problem solved.
