我在使用iOS 3.0模拟器时遇到此错误,但在3.1.3和3.2模拟器上却没有.

在创建符号断点后malloc_error_break,我在日志中看到了这一点:

从Jason Coco引用它不可能在UILabel中设置多个......但是

这样怎么办？

任何的想法？

是否可以在UILabel中设置混合颜色

例如"TEST"我可以将E设置为红色而将另一个设置为白色吗？

有可能构建facebook ios sdk来支持armv7s(Apple A6 cpu)吗？我已经尝试使用build_framework.sh再次重建,它仍然不支持armv7s!

我尝试通过sharekit将twitter集成到iphone app我已将我的应用程序注册到twitter.我不明白如何设置回调URL你能告诉我更多信息和步骤部署吗？

我知道此代码仅适用于此UINavigationController.

[self.navigationController setNavigationBarHidden:YES animated:YES];

我不知道,为什么按钮在工具栏设置为隐藏和取消隐藏后消失.我该怎么办呢？

设置按钮代码

-(void)viewDidAppear:(BOOL)animated {
    //NSLog(@"viewDidAppear ");

    [self becomeFirstResponder];
    //Create a button
    UIBarButtonItem *back = [[UIBarButtonItem alloc] 
                        initWithBarButtonSystemItem:UIBarButtonSystemItemRewind 
                target:self action:@selector(goback:)];

    UIBarButtonItem *fixspace1 = [[UIBarButtonItem alloc] 
                                 initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace 
                                 target:self action:nil];

    UIBarButtonItem *next = [[UIBarButtonItem alloc] 
                             initWithBarButtonSystemItem:UIBarButtonSystemItemFastForward 
                             target:self action:@selector(gofwd:)];
    UIBarButtonItem *stop = [[UIBarButtonItem alloc] 
                             initWithBarButtonSystemItem:UIBarButtonSystemItemStop 
                             target:self action:@selector(stopload:)];

    UIBarButtonItem *refresh = [[UIBarButtonItem alloc] 
                             initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh 
                             target:self action:@selector(refreshWeb:)];


    [self.navigationController.toolbar setItems:[NSArray arrayWithObjects:fixspace1, back, fixspace1, stop, fixspace1, next, fixspace1, nil] animated:YES];
    [self.navigationItem setRightBarButtonItem:refresh animated:YES];

    [self.navigationController.view addSubview:self.navigationController.toolbar];

    [stop release];
    [next release];
    [back release];
    [refresh release];
    [fixspace1 release];
}

我用这种方法设置我的按钮

当在Device 3.1.2上运行时,为什么它也传递if(NSClassFromString(@"MPMoviePlayerViewController")!= nil)并且执行iOS4的代码然后它会崩溃,如何解决这个问题？

               if(NSClassFromString(@"MPMoviePlayerViewController") != nil) {
                    // iOS 4 code
                    NSLog(@"MPMoviePlayerViewController");
                    MPMoviePlayerViewController *mp = [[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL URLWithString:AppDelegate.PushLink]];
                    if (mp) {
                        // save the movie player object
                        self.theMovie4 = mp;
                        [mp release];
                        //Present                       
                        [self presentMoviePlayerViewControllerAnimated:self.theMovie4];

                        // Play the movie!
                        self.theMovie4.moviePlayer.movieSourceType = MPMovieSourceTypeStreaming;
                        [self.theMovie4.moviePlayer play];
                    }
                }
                else {
                    //iOS 3 Code
                    AppDelegate = nil;
                    AppDelegate = [[UIApplication sharedApplication] delegate];
                    [AppDelegate ForceHideNavigationBar];
                    theMovie3 = nil;

                    [[NSNotificationCenter defaultCenter] addObserver:self 
                                                             selector:@selector(moviePreloadDidFinish:) 
                                                                 name:MPMoviePlayerContentPreloadDidFinishNotification 
                                                               object:theMovie3];

                    [[NSNotificationCenter defaultCenter] addObserver:self 
                                                             selector:@selector(moviePlayBackDidFinish:) 
                                                                 name:MPMoviePlayerPlaybackDidFinishNotification 
                                                               object:theMovie3];

我想在重复3次时计算','字符和子字符串.

输入:

9,1,2,3,9

输出:

9,1,2

NSMutableArray *images = [NSMutableArray arrayWithObjects:[UIImage imageNamed:@"JGirl 01.jpg"],
    [UIImage imageNamed:@"JGirl 03.jpg"], ... ,
    [UIImage imageNamed:@"JGirl 48.jpg"],
    nil];

self.view = [[[SlideShowView alloc] initWithImages:images byIndex:index] autorelease];

假设我的图像包含48个对象,但是当我调试图像时只有23个对象.

为什么我的所有图片都没有加载？

根据这篇文章 ,苹果现在也会拒绝这个代码吗？

以及如何实施苹果将批准的内容？
