UITableViewからの文字列で を作成しましたがNSMutableArray、上下にスクロールするとアプリがクラッシュします。もう 1 つの問題は、行を選択するとクラッシュすることNSMutableArrayです。
クラッシュのポイントはコードにコメントされています。
コード：
@synthesize daysArray, activeDaysArray;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
daysArray = [NSMutableArray arrayWithObjects:@"Mondays",@"Tuesday",@"Wednesday",@"Thursday",@"Friday",@"Saturdays", @"Sundays", nil];
activeDaysArray = [[NSMutableArray alloc]initWithCapacity:0];
}
return self;
}
#pragma Table View Delegates and DataSource methods
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
//This point is OK, it's returning 7 as it is supposed too
return [daysArray count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
cell.textLabel.text = [daysArray objectAtIndex:indexPath.row]; //Crashing here: EXC_BAD_ACCESS;
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
UITableViewCell* myCell = [tableView
cellForRowAtIndexPath:indexPath];
if ([myCell accessoryType] == UITableViewCellAccessoryNone) {
[myCell setAccessoryType:UITableViewCellAccessoryCheckmark];
[activeDaysArray addObject:indexPath.row]; //Crashing here: EXC_BAD_ACCESS
}else{
[myCell setAccessoryType:UITableViewCellAccessoryNone];
int indexOfObject = [activeDaysArray indexOfObject:indexPath.row];
[activeDaysArray removeObjectAtIndex:indexOfObject];
}
}
よろしく、 クラウディオ

myFile.h で:
@property(nonatomic, strong)NSMutableArray *daysArray;
@property(nonatomic, strong)NSMutableArray *activeDaysArray;
私はARCを使用していません！
