アプリケーションからビューにアクセスしようとするたびに、アプリケーションがすぐに閉じます。NSZombieEnabled をアクティブ化するログをキャプチャしました。これが私が得たものです：

明らかにtableViewが問題ですが、何が問題なのかわかりません。Interface Builder でどのようにリンクする必要がありますか? 私は .h にこれを持っています:
@interface RecargaOtroController : UIViewController <UINavigationControllerDelegate, UITableViewDataSource, UITableViewDelegate>{
BOOL agrandaRecarga;
}
IBOutlet UITableView *tableView;
@property (nonatomic, retain)IBOutlet UITableView *tableView;
UITextField *myLoc;
@property (nonatomic, retain)UITextField *myLoc;
これはtableViewに関する私の.mの一部です（私はそれを合成しました）：
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath*)indexPath{
NSLog(@"TABLE VIEW: %@",tableView);
NSLog(@"CELL");
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if(cell==nil){
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier]autorelease];
}
int r, g, b;
b = 0x005C84 & 0x0000FF;
g = ((0x005C84 & 0x00FF00) >> 8);
r = ((0x005C84 & 0xFF0000) >> 16);
UIColor *movistarColor = [UIColor colorWithRed:r/255.0f green:g/255.0f blue:b/255.0f alpha:100.0f];
cell.detailTextLabel.font = [UIFont fontWithName:@"Verdana" size:15.0];
cell.detailTextLabel.textColor = movistarColor;
cell.textLabel.font = [UIFont fontWithName:@"Verdana-Bold" size:14.0];
cell.textLabel.textColor = movistarColor;
if([ListaNumerosController hayDefault]==nil){
NSLog(@"NO HAY NUMEROS CARGADOS");
if(indexPath.row == 0){
cell.detailTextLabel.text = [NSString stringWithFormat:@"%@ (%@)", tarjetaSeleccionada.alias, tarjetaSeleccionada.numero];
}else if(indexPath.row == 1){
cell.detailTextLabel.text = @"Otro";
}else if(indexPath.row == 2){
myLoc = [[UITextField alloc] initWithFrame:CGRectMake(10, 10, 250, 40)];
myLoc.adjustsFontSizeToFitWidth = YES;
myLoc.textColor = movistarColor;
myLoc.textAlignment = UITextAlignmentLeft;
myLoc.highlighted = NO;
myLoc.clearsContextBeforeDrawing=YES;
myLoc.placeholder = @"Ingrese su número";
myLoc.delegate = self;
myLoc.font = [UIFont fontWithName:@"Verdana" size:14.0];
myLoc.clearButtonMode = UITextFieldViewModeNever; // no clear 'x' button to the right
if(myLoc.text.length!=10){
[myLoc becomeFirstResponder];
}
[myLoc setKeyboardType: UIKeyboardTypeNumberPad];
[myLoc setEnabled:YES];
[cell addSubview:myLoc];
}else /*if(indexPath.row == 3)*/{
cell.detailTextLabel.text = recarga.monto;
}
}else{
NSLog(@"HAY NUMEROS CARGADOS");
if(![telefonoSeleccionado.alias isEqualToString:@"Otro"]){
NSLog(@"NO SE SELECCIONO OTRO NUMERO");
if(indexPath.row == 0){
cell.detailTextLabel.text = [NSString stringWithFormat:@"%@ (%@)", tarjetaSeleccionada.alias, tarjetaSeleccionada.numero];
}else if(indexPath.row == 1){
cell.detailTextLabel.text = [NSString stringWithFormat:@"%@ (%@)",telefonoSeleccionado.alias,[telefonoSeleccionado.telefono substringFromIndex:6]];
}else if(indexPath.row == 2){
cell.detailTextLabel.text = recarga.monto;
myLoc.text = @"";
}else if(indexPath.row == 3){
cell.detailTextLabel.text = @"";
}
}else{
NSLog(@"SE SELECCIONO OTRO NUMERO");
if(indexPath.row == 0){
cell.detailTextLabel.text = [NSString stringWithFormat:@"%@ (%@)", tarjetaSeleccionada.alias, tarjetaSeleccionada.numero];
}else if(indexPath.row == 1){
cell.detailTextLabel.text = @"Otro";
}else if(indexPath.row == 2){
cell.detailTextLabel.text = @"";
}else if(indexPath.row == 3){
cell.detailTextLabel.text = recarga.monto;
}
}
}
return cell;
}
- (void)dealloc {
[super dealloc];
}
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
// Start listening for updates when visable
[tableView setDelegate:self];
[tableView reloadData];
}
- (void)viewWillDisappear:(BOOL)animated {
[super viewWillDisappear:animated];
// Stop listening for updates when not visable
[tableView setDelegate:nil];
}
問題はInterface Builderファイルにあるのではないかと考えています。何が問題なのかを理解する方法はありますか?
ありがとう！
更新: 私のアプリケーションは、テーブルを含むメイン ウィンドウで構成されています。各行をクリックすると、別のビューに移動します。新しいビュー (RecargaOtroController) には別のテーブルがあります。別のコントローラーを使用して、同じ方法で各ビューをインスタンス化します。
ThirdViewController.h
#import <UIKit/UIKit.h>
@interface ThirdViewController : UIViewController {
}
@end
ThirdViewController.m
#import "ThirdViewController.h"
@implementation ThirdViewController
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization.
}
return self;
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
}
- (void)viewDidUnload {
[super viewDidUnload];
}
- (void)dealloc {
[super dealloc];
}
次に、メイン画面である私の RootViewController:
RootViewController.h (抜粋)
#import <UIKit/UIKit.h>
@interface RootViewController : UITableViewController <UIAlertViewDelegate, UINavigationControllerDelegate, UITableViewDataSource, UITableViewDelegate> {
NSMutableArray *opcionesMenu;
BOOL agrandaRecarga;
}
IBOutlet UITableView *tableView;
@property (nonatomic, retain)IBOutlet UITableView *tableView;
RootViewController.m (抜粋)
ThirdViewController *detailViewController = nil;
if (indexPath.row == 1) {
[self showConfirmaRecargaMessage];
return;
}else if (indexPath.row == 2) {
detailViewController = [[RecargaOtroController alloc] initWithNibName:@"RecargaOtro" bundle:nil];
detailViewController.title = @"Recargar otro número o monto";
}else if (indexPath.row == 3) {
...
- (void)dealloc {
[super dealloc];
}
RecargaOtroController の割り当てを解除することはありません (また、インスタンス化する画面のどのクラスも、とにかく、それらは常に機能していました)。
