Getting error using iCarousel - ios

Question

This is for my iCarouselViewController.m
- (void)dealloc
{
//it's a good idea to set these to nil here to avoid
//sending messages to a deallocated viewcontroller
carousel1.delegate = nil;
carousel1.dataSource = nil;
carousel2.delegate = nil;
carousel2.dataSource = nil;
[carousel1 release];
[carousel2 release];
[items1 release];
[items2 release];
[super dealloc];
}
I am getting an error saying
'release' is unavailable: not available in automatic reference
counting mode ARC forbids explicit message send of 'release'
'release' is unavailable: not available in automatic reference
counting mode ARC forbids explicit message send of 'release'
'release' is unavailable: not available in automatic reference

and error in this code aswell
- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index reusingView:(UIView *)view
{
UILabel *label = nil;
//create new view if no view is available for recycling
if (view == nil)
{
view = [[[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 200.0f, 200.0f)] autorelease];
((UIImageView *)view).image = [UIImage imageNamed:#"page.png"];
view.contentMode = UIViewContentModeCenter;
label = [[[UILabel alloc] initWithFrame:view.bounds] autorelease];
label.backgroundColor = [UIColor clearColor];
label.textAlignment = UITextAlignmentCenter;
label.font = [label.font fontWithSize:50];
[view addSubview:label];
}
else
{
label = [[view subviews] lastObject];
}
saying
'autorelease' is unavailable: not available in automatic reference
counting mode ARC forbids explicit message send of
'autorelease' 'autorelease' is unavailable: not available in
automatic reference counting mode ARC forbids explicit message
send of 'autorelease'
How can I clear this error.
Update
Thank you for the answer I just have 4 error saying use of undeclared identifier imageArray1. and I know that this is happening. I just don't get " I assume you are just using app's bundle and we have two arrays of NSString which refer to each image: imageArray1 and imageArray2." Below is one of my save code and creating directory for one of my directories. Note: I have only one NSMutableArray called allImagesArray which I have declared in the header file.
NSArray *directoryNames = [NSArray arrayWithObjects:#"Apple",nil];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents folder
for (int i = 0; i < [directoryNames count] ; i++) {
NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:[directoryNames objectAtIndex:i]];
if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath])
[[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:nil]; //Create folder
NSString *folderPath = [documentsDirectory stringByAppendingPathComponent:#"Tops"]; NSData *imageData = UIImagePNGRepresentation(captureImage.image);
time_t unixtime = (time_t)[[NSDate date]timeIntervalSince1970];
NSString *timestamp = [NSString stringWithFormat:#"%ldTopsImage.PNG",unixtime];
NSString *filePath = [folderPath stringByAppendingPathComponent:timestamp];
[imageData writeToFile:filePath atomically:YES];
}
}
Update 4
ThiS?
- (void)viewDidLoad
{
[super viewDidLoad];
//configure carousel
imageArray1 = [[NSMutableArray alloc] init];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *location=#"apple";
NSString *fPath = [documentsDirectory stringByAppendingPathComponent:location];
NSArray * directoryContent = [[NSFileManager defaultManager] directoryContentsAtPath: fPath];
imageArray1 = directoryContent;
imageArray2 = [[NSMutableArray alloc] init];
NSString *location=#"green";
NSString *fPath = [documentsDirectory stringByAppendingPathComponent:location];
NSArray *directoryContent = [[NSFileManager defaultManager] directoryContentsAtPath: fPath];
imageArray2 = directoryContent;

Answer 1

This is not an iCarousel issue. You are using statements like release, autorelease in your code. Remove it. In ARC you do not need to do memory management manually. That is why ARC is there.
UPDATE:
According to your comments, you are facing problems in displaying images for Mutiple Carousels.
I assume you are using two iCarousel objects. lets name them carousel1 and carousel2.
Also, it seems you are using sandbox for saving images. If this is the case, then you have to fetch images from your sandbox using NSFileManager. You need to keep looking at how to do that, but the code for iCarousel will remain more or less same in that case as well. Here, for simplicity case I assume you are just using app's bundle and we have two arrays of NSString which refer to each image: imageArray1 and imageArray2.
In viewDidLoad, set delegate and datasource objects of each carousel as self
carousel1.delegate = self;
carousel1.dataSource = self;
carousel2.delegate = self
carousel2.dataSource = self;
Implement datasource methods accordingly:
- (NSUInteger)numberOfItemsInCarousel:(iCarousel *)carousel
{
//return the total number of items in the carousel
if (carousel == carousel1)
{
return [imageArray1 count];
}
else
{
return [imageArray2 count];
}
}
- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index reusingView:(UIView *)view
{
UILabel *label = nil;
//create new view if no view is available for recycling
if (view == nil)
{
view = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 200.0f, 200.0f)];
UIImage *image;
if (carousel == carousel1)
{
image = [UIImage imageWithContentsOfFile:[imageArray1 objectAtIndex:index]];
((UIImageView *)view).image = image;
}
else
{
image = [UIImage imageWithContentsOfFile:[imageArray2 objectAtIndex:index]];
((UIImageView *)view).image = image;
}
}
return view;
}

Well it is actually really easy, you have ticked the "Use Automatic Reference Counting" (ARC) box when creating your XCode project. To solve it just go to your target, (iCarousel I assume) and do this "buldsettings" ---> objective-c automaticrefcount :NO
The compiler should then work. What ARC does is do this stuff automatically for you, so you don't have to write auto release and release statements, but if you need them do what I suggested. Otherwise remove these release and autorelease statements.

Answer 3

That is because you're using ARC in your project and the code you showed here doesn't. To disable it in those classes add -fno-objc-arc. You can do so by going into the targets Build Phases tab. In Compile Sources group, double-click the file (class) and add the -fno-objc-arc flag.
Or you could just remove all release messages.
