从我昨天问的问题开始。放大寻呼ScrollView
我有一个分页scrollView,只有在y轴的页面。目前,我有它的工作,我有一个UIImageView数组包含不同的UIImages和photoScroller工作正如我所料,但是当我尝试添加imageView作为另一个scrollview的子视图,以允许捏和缩放它打破了画廊。
按中断我的意思是它只加载第一个图像,但剩下的空间为其他图像,而不是捏发生。
- (void)loadView{
// Creates 4 images from the file names
UIImage *img0 = [UIImage imageNamed:@"29.png"];
UIImage *img1 = [UIImage imageNamed:@"33.png"];
UIImage *img2 = [UIImage imageNamed:@"IMAG0085.JPG"];
UIImage *img3 = [UIImage imageNamed:@"DSC00081.JPG"];
NSMutableArray *imgArray = [[NSMutableArray alloc] initWithObjects:img0,img1,img2, img3, nil]; //Places images into array
CGRect pagingScrollViewFrame = [[UIScreen mainScreen] bounds]; // Creates initial scrollViewFrame to be the size of the screen
pagingScrollViewFrame.origin.x -= 10; //moves it 10px to the left
pagingScrollViewFrame.size.width += 20; //adds 20px to the right creating a 10px blank buffer either side
pagingScrollView = [[UIScrollView alloc] initWithFrame:pagingScrollViewFrame]; //Creates the pagingScrollView with the size specified with the frame
pagingScrollView.pagingEnabled = YES; //allow paging
pagingScrollView.backgroundColor = [UIColor blackColor]; //background black
pagingScrollView.contentSize = CGSizeMake(pagingScrollViewFrame.size.width * [imgArray count], pagingScrollViewFrame.size.height); //sets the width of the scroll view depending on the number in amges in the array.
self.view = pagingScrollView; //add the pagingScrollView to the main view
for (int i=0; i < [imgArray count]; i++) { //loop to add the images to an imageView and then add them to the paging ScrollView
/*--------Gets the image from the array and places it in an imageView------*/
UIImageView *page = [[UIImageView alloc] initWithImage: [imgArray objectAtIndex:i]];
page.frame = [[UIScreen mainScreen] bounds];
page.contentMode = UIViewContentModeScaleAspectFit;
//[page.setClipsToBounds:YES];
CGRect cgRect = [[UIScreen mainScreen] bounds];
CGSize cgSize = cgRect.size;
[page setFrame:CGRectMake((i*pagingScrollViewFrame.size.width)+10, 0, cgSize.width, cgSize.height)];
/*--------Creates Zooming scrollView and adds the imageView as a subView------*/
UIScrollView *zoomingScrollView = [[UIScrollView alloc] initWithFrame:cgRect];
zoomingScrollView.delegate = self;
zoomingScrollView.maximumZoomScale = 4.0;
zoomingScrollView.clipsToBounds = YES;
[zoomingScrollView addSubview:page];
[pagingScrollView addSubview:zoomingScrollView];
}}
- (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView{
NSArray *array = [scrollView subviews];
return [array lastObject];
}
