自动调整图像大小没有 imageView

发布于 2024-09-24 22:19:00 字数 657 浏览 3 评论 0原文

我在我的应用程序中使用 AFOpenFlow，但现在的问题是，我使用的图片大小不一样，因为它们来自网络！我怎样才能在 iPhone 的视图下自动调整图像大小？？？这是我的此方法的代码：

- (void)viewDidLoad {
    [super viewDidLoad];

    // loading images into the queue

    loadImagesOperationQueue = [[NSOperationQueue alloc] init];


    NSString *imageName;
    for (int i=0; i < 10; i++) {
        imageName = [[NSString alloc] initWithFormat:@"cover_%d.jpg", i];
        [(AFOpenFlowView *)self.view setImage:[UIImage imageNamed:imageName] forIndex:i];
        [imageName release];
        NSLog(@"%d is the index",i);

    }
    [(AFOpenFlowView *)self.view setNumberOfImages:10];


}

预先感谢您马可

i am using AFOpenFlow in my app, but now the Problem is,
the pictures I use are not the same size because they are from the web!
And how can i autoResizing the image at the view of the iPhone???
Here is my code from this method:

- (void)viewDidLoad {
    [super viewDidLoad];

    // loading images into the queue

    loadImagesOperationQueue = [[NSOperationQueue alloc] init];


    NSString *imageName;
    for (int i=0; i < 10; i++) {
        imageName = [[NSString alloc] initWithFormat:@"cover_%d.jpg", i];
        [(AFOpenFlowView *)self.view setImage:[UIImage imageNamed:imageName] forIndex:i];
        [imageName release];
        NSLog(@"%d is the index",i);

    }
    [(AFOpenFlowView *)self.view setNumberOfImages:10];


}

Thank you beforehand

在设置开放流程之前缩放图像
更改循环中的代码如下：

imageName = [[NSString alloc] initWithFormat:@"cover_%d.jpg", i];
UIImage *oriImage = [UIImage imageNamed:imageName];
[imageName release];

UIImage *requiredImage = [UIImage imageWithCGImage:[oriImage CGImage] scale:768/520.0 orientation:UIImageOrientationUp];

[(AFOpenFlowView *)self.view setImage:requiredImage forIndex:i];
NSLog(@"%d is the index",i);

scale your image before set to open flow
change your code in the loop as below:

imageName = [[NSString alloc] initWithFormat:@"cover_%d.jpg", i];
UIImage *oriImage = [UIImage imageNamed:imageName];
[imageName release];

UIImage *requiredImage = [UIImage imageWithCGImage:[oriImage CGImage] scale:768/520.0 orientation:UIImageOrientationUp];

[(AFOpenFlowView *)self.view setImage:requiredImage forIndex:i];
NSLog(@"%d is the index",i);
