试试这个，

int counter; 
NSMutableArray * imageArray; 

-(void)takePicture 
{ 
     counter=0; 
     UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init]; 
[imagePicker setSourceType:UIImagePickerControllerSourceTypeCamera]; 
[imagePicker setDelegate:self]; 
[self presentModalViewController:imagePicker animated:YES]; 
[imagePicker release]; 
} 

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info 
{ 
UIImage *image= [info objectForKey:UIImagePickerControllerEditedImage]; 

[imageArray addObject:image]; 
counter++; 
if (counter<PhotoCount) 
{ 
    [self dismissModalViewControllerAnimated:NO]; 
    UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init]; 
    [imagePicker setSourceType:UIImagePickerControllerSourceTypeCamera]; 
    [imagePicker setDelegate:self]; 
    [self presentModalViewController:imagePicker animated:NO]; 
    [imagePicker release]; 
} 
else 
{ 
    [self dismissModalViewControllerAnimated:YES]; 
} 

}

PhotoCount是你想拍摄照片的数量。

/*我在询问有关在拍摄多张图像时同时保存图像的问题。那时我们不知道我们要拍多少张图片？此外，图像应该在图像上拍摄精确的图像。节省过程也适用于背景模式。你能帮我吗 */ – 2014-12-12 05:55:01
