App crashes on releasing custom Table Cell - iphone

Question

i have a problem with my app crashing when my custom TableViewCell gets released.
the Cell gets initialized like the following in cellForRowAtIndexPath:
SearchTableViewCell *cell = (SearchTableViewCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[SearchTableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
}
cell.nameLabel.text = #"some text";
cell.addressLabel.text = #"some more text";
the cell class itself looks like this
#import <UIKit/UIKit.h>
#class EGOImageView;
#interface SearchTableViewCell : UITableViewCell {
UILabel *nameLabel;
UILabel *addressLabel;
EGOImageView *imageView;
}
#property (nonatomic, retain) UILabel *nameLabel;
#property (nonatomic, retain) UILabel *addressLabel;
- (UILabel *)labelWithColor:(UIColor*)color selectedColor:(UIColor*)selectedColor fontSize:(CGFloat)fontSize bold:(BOOL)bold frame:(CGRect)rect;
- (void)setThumb:(NSString*)thumb;
#end
.m
#import "SearchTableViewCell.h"
#import "EGOImageView.h"
#import "UIView+Additions.h"
#implementation SearchTableViewCell
#synthesize nameLabel = _nameLabel, addressLabel = _addressLabel;
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier {
if ((self = [super initWithStyle:style reuseIdentifier:reuseIdentifier])) {
// Initialization code
UIView *myContentView = self.contentView;
// Name
_nameLabel = [self labelWithColor:[UIColor blackColor] selectedColor:[UIColor whiteColor] fontSize:16.0f bold:YES frame:CGRectMake(140.0f, 16.0f, 181.0f, 21.0f)];
[myContentView addSubview:_nameLabel];
[_nameLabel release];
// Adress
_addressLabel = [self labelWithColor:[UIColor blackColor] selectedColor:[UIColor whiteColor] fontSize:13.0f bold:YES frame:CGRectMake(140.0f, _nameLabel.bottom, 181.0f, 21.0f)];
[myContentView addSubview:_addressLabel];
[_addressLabel release];
// Image
imageView = [[EGOImageView alloc] initWithPlaceholderImage:[UIImage imageNamed:#"placeholder.png"]];
imageView.frame = CGRectMake(9.0f, 9.0f, 120.0f, 80.0f);
[myContentView addSubview:imageView];
[imageView release];
}
return self;
}
- (UILabel *)labelWithColor:(UIColor*)color selectedColor:(UIColor*)selectedColor fontSize:(CGFloat)fontSize bold:(BOOL)bold frame:(CGRect)rect {
UIFont *font;
if(bold) {
font = [UIFont boldSystemFontOfSize:fontSize];
} else {
font = [UIFont systemFontOfSize:fontSize];
}
UILabel *label = [[UILabel alloc] initWithFrame:rect];
label.backgroundColor = [UIColor clearColor];
label.textColor = color;
label.highlightedTextColor = selectedColor;
label.font = font;
return label;
}
- (void)setThumb:(NSString*)thumb {
imageView.imageURL = [NSURL URLWithString:thumb];
}
- (void)willMoveToSuperview:(UIView *)newSuperview {
[super willMoveToSuperview:newSuperview];
if(!newSuperview) {
[imageView cancelImageLoad];
}
}
- (void)dealloc {
[_addressLabel release];
[_nameLabel release];
[imageView release];
[super dealloc];
}
#end
does anybody have an idea why my app crashes on releasing such a cell? commenting out the 2 labels and the image view on dealloc method, the app doesn't crash, but then there will be a memory leak right?
thanks for all hints! please leave a comment if something is unclear!

Answer 1

imageView is being released twice, once when it is created:
imageView = [[EGOImageView alloc] initWithPlaceholderImage:[UIImage imageNamed:#"placeholder.png"]];
imageView.frame = CGRectMake(9.0f, 9.0f, 120.0f, 80.0f);
[myContentView addSubview:imageView];
[imageView release];
and once in dealloc:
- (void)dealloc {
[_addressLabel release];
[_nameLabel release];
[imageView release];
[super dealloc];
}

Answer 2

You already release the memory for that labels after adding to view,again you are trying to release memory those objects are already relese in dealloc method that's why it is killing.if you remove 3 statements in dealloc method it will not crash.

Answer 3

I think the Problem is that you release your properties direct in the initWithStyle function and additional to that in dealloc again. Try removing the release from initWithStyle:
Furthermore you named your variables without _ in the interface but with _ #synthesize'ing in the implementation
