カスタムTableViewCellがリリースされると、アプリがクラッシュするという問題があります。私が試したコードを以下に示します。変数の名前には当てはまりませんでした。
セルは、cellForRowAtIndexPathで次のように初期化されます。
static NSString *CellIdentifier1 = @"CellIdentifier";
static NSString *CellIdentifier2 = @"Cell";
if (indexPath.section == 0 && indexPath.row==0)
{
CustomCell *cell = (CustomCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier1];
if (cell == nil)
{
cell = [[[CustomCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier1] autorelease];
cell.backgroundView = [ [[UIImageView alloc] initWithImage:[ [UIImage imageNamed:@"dfdfdf.png"] stretchableImageWithLeftCapWidth:0.0 topCapHeight:5.0] ]autorelease];
}
[cell.fgfbutton addTarget:self action:@selector(callAction:) forControlEvents:UIControlEventTouchUpInside];
cell.myImageView.image=[UIImage imageNamed:@"fdfdfdf.png"];
cell.fddfdbutton.tag=indexPath.section+1;
return cell;
}
else if (indexPath.section == 1 && indexPath.row==0)
{
Customcellwithimage *cell = (Customcellwithimage *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier2];
if (cell == nil)
{
cell = [[[Customcellwithimage alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier2] autorelease];
cell.backgroundView = [ [[UIImageView alloc] initWithImage:[ [UIImage imageNamed:@"fetrtrtrt.png"] stretchableImageWithLeftCapWidth:0.0 topCapHeight:5.0] ]autorelease];
}
cell.selectionStyle = UITableViewCellSelectionStyleNone;
[cell.dfdfbutton1 addTarget:self action:@selector(callAction:) forControlEvents:UIControlEventTouchUpInside];
return cell;
}
カスタムセルクラスでは、deallocメソッドでセルオブジェクトをリリースしています。カスタムセルでは、次のように実行しています。
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) {
nameLabel = [[UILabel alloc]init];
[nameLabel setFont:[UIFont fontWithName:@"Helvetica-Bold" size:16]];
nameLabel.textAlignment = UITextAlignmentLeft;
nameLabel.textColor = [UIColor blackColor];
nameLabel.numberOfLines = 0;
nameLabel.backgroundColor =[UIColor clearColor];
nameLabel.adjustsFontSizeToFitWidth = NO;
sfdfbutton = [UIButton buttonWithType:UIButtonTypeCustom];
[sdsdbutton setImage:[UIImage imageNamed:@"_it.png"] forState:UIControlStateNormal];
[sdbutton setImage:[UIImage imageNamed:@"ed.png"] forState:UIControlStateSelected];
sdsdbutton.selected=NO;
myImageView = [[UIImageView alloc] init];
bottomborder=[[UIImageView alloc] init];
UIImage *img1 = [UIImage imageNamed:@"_bg.png"];
[bottomborder setImage:img1];
[self.contentView addSubview:nameLabel];
[self.contentView addSubview:myImageView];
}
return self;
}
- (void)layoutSubviews {
[super layoutSubviews];
//CGRect contentRect = self.contentView.bounds;
//CGFloat boundsX = contentRect.origin.x;
CGRect frame;
//frame= CGRectMake(0 ,0, 300, 135);
//cellview.frame = frame;
frame= CGRectMake(60 ,8, 220, 20);
nameLabel.frame = frame;
myImageView.frame = CGRectMake(10,6,40,40);
NSLog(@"nameLabel frame: %@", NSStringFromCGRect(myImageView.frame));
nhghbutton.frame =CGRectMake(4,12 + frame.origin.y + frame.size.height, 82, 35);
}
- (void)setSelected:(BOOL)selected animated:(BOOL)animated
{
[super setSelected:selected animated:animated];
}
- (void)dealloc {
[bottomborder release];
[myImageView release];
[label release];
[super dealloc];
}
