問題描述

我有一張像這樣的圖片:

I have an image like:

當我將圖像加載到 uiimageview，然后作為子視圖添加到 uiscrollview 時，開始時圖像顯示如下:

When I load the image to uiimageview and then adding as a subview to uiscrollview, at start the image is showing like:

問題是我想在開始時看到所有適合屏幕的圖像，但它顯示已經縮放.有沒有辦法處理這個請幫忙...

The problem is I want to see all the image fit to screen at start but it is showing already zoomed. Is there a way to handle this please help ...

我有這樣的代碼:

[self.view addSubview:scrollView];
UIImageView *tempImageView = 
[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"Tree.jpg"]];
self.imageView = tempImageView;
[tempImageView release];
[scrollView setContentMode:UIViewContentModeScaleAspectFit];
[imageView sizeToFit];
scrollView.backgroundColor=[UIColor blackColor];
scrollView.contentSize = imageView.frame.size;
scrollView.minimumZoomScale = scrollView.frame.size.width / imageView.frame.size.width;
scrollView.maximumZoomScale = 4.0;
[scrollView setZoomScale:1.0];
scrollView.clipsToBounds = YES;
scrollView.delegate = self;
[scrollView addSubview:imageView];

推薦答案

可能你正在尋找這個，

UIImageView *tempImageView = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"Watson.jpg"]] autorelease];
tempImageView.frame = scrollView.bounds;
self.imageView = tempImageView;

scrollView.backgroundColor = [UIColor blackColor];
scrollView.minimumZoomScale = 1.0  ;
scrollView.maximumZoomScale = imageView.image.size.width / scrollView.frame.size.width;
scrollView.zoomScale = 1.0;
scrollView.delegate = self;

[scrollView addSubview:imageView];

這篇關于UIImage 在開始時不適合 UIScrollView的文章就介紹到這了，希望我們推薦的答案對大家有所幫助，也希望大家多多支持html5模板網！
