Ios 升级后，XCode在断点或日志记录时未中断（4.2->；4.3）

注意：此问题与XCode有关。原始问题已就位，但标题已更新以反映实际问题。

我使用表视图进行表单输入，并创建了一种库，用于向表中添加输入字段。在输入字段上，我需要一个图像捕获字段来启动设备摄像头

我已经声明了如下接口

@interface PhotoBlockCell : UITableViewCell < UINavigationControllerDelegate, UIImagePickerControllerDelegate > 

- (IBAction)addPhoto:(id)sender{
    if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera] == YES){
        if ([sender isKindOfClass:[UIButton class]])
             activeButton = (UIButton*)sender;
        UIImagePickerController * imagePicker = [[UIImagePickerController alloc] init];
        imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
        imagePicker.delegate = self;
        [self.delegate presentModalViewController:imagePicker animated:YES];
    }
}

为了启动图像捕获，我让一个委托指向容纳我的表视图的父视图控制器。我使用UIImagePickerController启动设备摄像头，如下所示

@interface PhotoBlockCell : UITableViewCell < UINavigationControllerDelegate, UIImagePickerControllerDelegate > 

- (IBAction)addPhoto:(id)sender{
    if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera] == YES){
        if ([sender isKindOfClass:[UIButton class]])
             activeButton = (UIButton*)sender;
        UIImagePickerController * imagePicker = [[UIImagePickerController alloc] init];
        imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
        imagePicker.delegate = self;
        [self.delegate presentModalViewController:imagePicker animated:YES];
    }
}

这样启动设备摄像头时不会出现问题，但我似乎无法捕获结果照片。添加断点似乎表明didFinishPickingMediaWithInfo从未触发

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {

    // button 1
    if (activeButton == button1) {
        photo1 = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
    }

    // dismiss the picker
    [picker dismissModalViewControllerAnimated:YES];
}

但是，视图控制器将被解除。你知道问题出在哪里吗？

显然，这一直都在起作用，问题与最近从XCode 4.2升级到4.3有关（我今天被迫在将手机升级到5.1后升级）。似乎我的设备内部的某个标志在调试时阻止了中断/记录。一次手动暂停就把事情弄清楚了

我按照指示解决了这个问题

使用XCode中的暂停按钮暂停应用程序

添加新断点并继续

在新断点处断开后继续
