Question

我仍然很擅长编码，并且正在尝试合并两个项目的示例代码。

问题：

基本上，我想在for循环中捕获图像文件的名称（全部名为card1.gif，card2.gif等）并将其设置为_imagename变量，因此我可以将文件名传递给facebook用邮件包含图像的代码。不确定如何将FB代码与图像显示循环代码组合在一起。

感谢您的帮助!!

CGRect newViewSize = Scroller.bounds;
int NumberOfImages = 20;
int i;
for(i=0;i<NumberOfImages;i++){

    if(i == 0){
        //Setup first picture
        UIImageView *ImgView = [[UIImageView alloc] initWithFrame:newViewSize];
        NSString *FilePath = [NSString stringWithFormat:@"Page_%d.png", i];
        [ImgView setImage:[UIImage imageNamed:FilePath]];
        [Scroller addSubview:ImgView];
    }else{
        //Setup the rest of the pictures
        newViewSize = CGRectOffset(ViewSize, Scroller.bounds.size.width, 0);
        UIImageView *ImgView = [[UIImageView alloc] initWithFrame:newViewSize];
        NSString *FilePath = [NSString stringWithFormat:@"Page_%d.png", i];
        [ImgView setImage:[UIImage imageNamed:FilePath]];
        [Scroller addSubview:ImgView];
    }
}

[self.view addSubview:Scroller];

}

- (IBAction)facebook:(id)sender {
    if([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) {
        SLComposeViewController *controller = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];


        [controller setInitialText:@"Insert FB text here"];
        [controller addURL:[NSURL URLWithString:@"http://www.cnn.com"]];
        [controller addImage:[UIImage imageNamed:_imagename]];
        [self presentViewController:controller animated:YES completion:Nil];
    }
}

Answer 1

int amountOfPictures = 20;
NSMutableArray *arrayOfPictureNames = [NSMutableArray array];
for(int x = 0; x < amountOfPictures; x++) {
   [arrayOfPictureNames addObject:[NSString stringWithFormat:@"card%d.png", x]];


}

现在你应该有一个充满了card1.png card2.png格式图片名称的数组。

NSString从for循环传递变量。
