ios - 加载空 Nib 导致应用商店评论崩溃

Question

Apple 在加载仅包含 View 和背景颜色的 Nib 时设法使我的应用程序崩溃。我似乎无法在我的设备上发生崩溃。这可能是内存问题还是我在代码中做了一些愚蠢的事情？报告和代码附在下面:

我在 View Controller 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

我认为您的 iOS 部署目标 < 6.0 并且您没有关闭自动布局。转到“ View ”->“实用程序”->“显示文件检查器”并取消选中“使用自动布局”选项。
