更新：我無法找到導致問題的原因我正在使用beta SDK，並且在使用最終SDK時，問題消失了。我不知道我做錯了什麼。抱歉。我想刪除這個，但不能。被釋放的指針未被分配
您好，我有以下錯誤：
的malloc：*錯誤對象0x2087000：被釋放的指針沒有被分配 *設置malloc_error_break斷點調試
我不知道是什麼對象是。我不知道如何找到它。任何人都可以向我解釋如何（以及在哪裏）使用malloc_history。我已經在malloc_error_break中設置了一個斷點，但我無法找到該地址處的對象。我從nsmutablearray中移除一個對象並手動彈出視圖控制器後收到此消息。如果我註釋掉[reviewUpload.images removeObject：self.reviewUploadImg]這一行，它不會給我這個錯誤，但當然這對我沒有用處。
- (void) removeImage
{
debugLog(@"reviewUploadImg %@", self.reviewUploadImg);
debugLog(@"reviewUpload %@", self.reviewUpload);
debugLog(@"reviewUploadImg thumb %@", self.reviewUploadImg.thumb);
[reviewUpload.images removeObject: self.reviewUploadImg];
[self.navigationController popViewControllerAnimated:TRUE];
}
我試圖打印出3個地址，但他們都不是被釋放但未被分配的地址。
我從UIImagePickerController添加圖像。
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
UIImage *pickedImage = (UIImage *)[info objectForKey: UIImagePickerControllerEditedImage];
if (!pickedImage)
pickedImage = (UIImage *)[info objectForKey: UIImagePickerControllerOriginalImage];
if (!reviewUpload.images)
reviewUpload.images = [[NSMutableArray alloc] initWithCapacity: 5];
//UIImage *thumbImage = [pickedImage copyResizedImage: CGSizeMake(120, 120)];
UIImage *thumbImage = [pickedImage copyResizedImage:CGSizeMake(120, 120) withPaddingColor: [UIColor lightGrayColor]];
ReviewUploadImage *rui = [[ReviewUploadImage alloc] init];
rui.thumb = thumbImage;
[thumbImage release];
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat: @"yyyyMMddHHmmssSS"];
NSDate *date = [NSDate date];
NSString *tmpFileName = [dateFormatter stringFromDate: date];
[dateFormatter release];
NSString *path = [NSTemporaryDirectory() stringByAppendingPathComponent: tmpFileName];
NSData *imageData = [[NSData alloc] initWithData: UIImageJPEGRepresentation(pickedImage, 0.90)];
[imageData writeToFile: path atomically: TRUE];
[imageData release];
rui.path = path;
[reviewUpload.images addObject: rui];
debugLog(@"rui rc %i", rui.retainCount);
[rui release];
[self dismissModalViewControllerAnimated:TRUE];
}
我不認爲我有什麼錯在這裏：ReviewUpload有一個圖像陣列可能含有ReviewUploadImage對象。在這些類的實現中，我只有釋放方法，我只是釋放我必須釋放的成員。
@interface ReviewUpload : NSObject
{
NSString *title;
NSString *tags;
NSString *text;
NSInteger rating;
NSMutableArray *images;
NSInteger idCompany;
NSInteger idProduct;
}
@property(nonatomic, copy) NSString *title;
@property(nonatomic, copy) NSString *tags;
@property(nonatomic, copy) NSString *text;
@property(nonatomic, assign) NSInteger rating;
@property(nonatomic, retain) NSMutableArray *images;
@property(nonatomic, assign) NSInteger idCompany;
@property(nonatomic, assign) NSInteger idProduct;
@end
@interface ReviewUploadImage : NSObject
{
UIImage *thumb;
NSString *path;
}
@property(nonatomic, retain) UIImage *thumb;
@property(nonatomic, copy) NSString *path;
@end
是不是有一種簡單的方式來獲得一個ADRESS Objective-C的對象？
更新： 如果我刪除這些行中的任何一個，我不會收到錯誤。我不知道該說什麼這很奇怪。
[reviewUpload.images removeObject: self.reviewUploadImg];
[self.navigationController popViewControllerAnimated:TRUE];
更新：如果在「didFinishPickingMediaWithInfo」中選擇的圖像爲零，則不顯示錯誤。也許它必須按照我創建縮略圖的方式做些事情。這是創建它的方法。如果有人有任何想法，請幫助。
-(UIImage *) copyResizedImage:(CGSize) thumbSize withPaddingColor: (UIColor *) bgColor
{
CGFloat resizedProp = thumbSize.width/thumbSize.height;
CGFloat imageProp = self.size.width/self.size.height;
CGSize newSize;
CGFloat factor;
if (imageProp > resizedProp) //image is wider
factor = thumbSize.width/self.size.width;
else
factor = thumbSize.height/self.size.height;
newSize.width = self.size.width * factor;
newSize.height = self.size.height * factor;
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
UIImage *resizedImage;
UIGraphicsBeginImageContext(thumbSize);
CGContextRef drwContextRef = UIGraphicsGetCurrentContext();
CGContextSetFillColorWithColor(drwContextRef, bgColor.CGColor);
CGContextFillRect(drwContextRef, CGRectMake(0, 0, thumbSize.width, thumbSize.height));
CGRect imageRect = CGRectMake(
(thumbSize.width - newSize.width)/2.0,
(thumbSize.height - newSize.height) /2.0, newSize.width, newSize.height);
[self drawInRect:imageRect];
resizedImage = UIGraphicsGetImageFromCurrentImageContext(); // this is autoreleased and i dont need it
UIGraphicsEndImageContext();
[resizedImage retain];
[pool release];
return resizedImage;
}
你可以把你的代碼初始化reviewUploadImg嗎？什麼是reviewUpload？它是什麼樣的對象？這將有助於更好地理解您的問題 – 2010-05-05 07:41:01
reviewUploadImg是ReviewUploadImage類，用於存儲Review的評論圖像（ReviewUpload類）。用戶可以爲公司或產品撰寫評論，並可將圖片附加到reviewUpUp.images中存儲的評論中。 – 2010-05-05 07:48:06
