【中文标题】加载空笔尖导致应用商店评论崩溃【英文标题】：Loading empty nib causing crash on appstore review 【发布时间】：2013-06-04 13:09:58 【问题描述】：Apple 在加载仅包含视图和背景颜色的 nib 时设法让我的应用程序崩溃。我似乎无法在我的设备上遇到崩溃。可能是内存问题还是我在代码中做了一些愚蠢的事情？下面附上报告和代码：

8 CodeFriend 0x000b221a -[AppDelegate settingAct:] (AppDelegate.m:127)
我在视图控制器中使用的代码：
#import "ThemesPopOverViewController.h"
@interface ThemesPopOverViewController ()
@end
@implementation ThemesPopOverViewController
@synthesize tableView;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self)
themes = [[NSArray alloc] initWithObjects:kRegexHighlightViewThemeArray];
self.tableView = nil;
self.tableView = [[UITableView alloc] initWithFrame:CGRectMake(20, 0, self.view.frame.size.width - 40, 350)];
[self.tableView setBackgroundColor:[UIColor clearColor]];
[self.tableView setDelegate:self];
[self.tableView setDataSource:self];
[self.view addSubview:self.tableView];
int item = [themes indexOfObject:theDelegate.codeView.currentTheme];
NSIndexPath *indexPath = [NSIndexPath indexPathForItem:item inSection:0];
[self.tableView selectRowAtIndexPath:indexPath animated:YES scrollPosition:UITableViewScrollPositionNone];
return self;
- (void)viewDidLoad
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
- (void)didReceiveMemoryWarning
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
return 1; //count of section
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
//NSLog(@"%d",themes.count);
return [themes count]; //count number of row from counting array hear cataGorry is An Array
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath
static NSString *MyIdentifier = @"MyIdentifier";
UITableViewCell *cell = [self.tableView dequeueReusableCellWithIdentifier:MyIdentifier];
if (cell == nil)
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:MyIdentifier];
UIView *bgColorView = [[UIView alloc] init];
[bgColorView setBackgroundColor:[UIColor colorWithRed:25/255.0f green:185/255.0f blue:152/255.0f alpha:1.0f]];
[cell setSelectedBackgroundView:bgColorView];
[cell.textLabel setFont:[UIFont fontWithName:@"Helvetica" size:16]];
cell.textLabel.text = [themes objectAtIndex: indexPath.row];
return cell;
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
NSLog(@"%d", indexPath.row);
[theDelegate.codeView setHighlightThemeFromString:[themes objectAtIndex:indexPath.row]];
[theDelegate removePop];
@end
H 文件：
#import <UIKit/UIKit.h>
#import "AppDelegate.h"
@interface ThemesPopOverViewController : UIViewController <UITableViewDataSource, UITableViewDelegate>
NSArray *themes;
@property (nonatomic, retain) UITableView *tableView;
@end

【问题讨论】：
【参考方案1】：我认为您的 ios 部署目标 实用程序->显示文件检查器并取消选中“使用自动布局”选项。
【讨论】：
我怀疑是这种情况，因为错误报告来自 ios 6.1.3 并且布局是空的并且我以编程方式添加所有元素，但是无论如何我都将其关闭，以及其他一些更改到代码。现在它被送回苹果。 More about your hunch【参考方案2】：在另一台机器上加载项目显示错误，在过程中的某个地方完成了一些重构，只有代码中的 nib 名称没有更新。因此，以某种方式缓存，旧的 nib 被 xcode 使用。然而，在存档中这些笔尖不存在，因此崩溃。我应该尝试清理项目！并仔细查看了代码！
