我做了一個帶有頁面的UIScrollView。在每一頁上,我將有一個UIImageView與UIScrollView。我想以這種方式處理每個頁面上圖像的縮放。但縮放委託方法沒有被調用。 這裏是我的代碼:UIScrollView縮放視圖沒有被調用
verticalScroll=[[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 768, 1024)];
horizontalScroll=[[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 1024, 768)];
verticalScroll.backgroundColor=[UIColor purpleColor];
verticalScroll.pagingEnabled=YES;
verticalScroll.contentSize=CGSizeMake(768*[largeImagesFromGallery count], 1024);
horizontalScroll.backgroundColor=[UIColor blackColor];
horizontalScroll.pagingEnabled=YES;
horizontalScroll.contentSize=CGSizeMake(1024*[largeImagesFromGallery count], 768);
float cofVert=1.34f;
for(int i=0; i<[largeImagesFromGallery count]; i++)
{
UIImage *temp=[largeImagesFromGallery objectAtIndex:i];
UIScrollView *svVert=[[UIScrollView alloc] initWithFrame:CGRectMake(i*768, 0, temp.size.width/cofVert, temp.size.height/cofVert)];
svVert.contentSize=CGSizeMake(temp.size.width/cofVert, temp.size.height/cofVert);
svVert.zoomScale=3.0f;
svVert.delegate=self;
UIImageView *imageVert=[[UIImageView alloc] initWithFrame:CGRectMake(0, 0, temp.size.width/cofVert, temp.size.height/cofVert)];
imageVert.image=temp;
imageVert.tag=2000;
UIScrollView *svHor=[[UIScrollView alloc] initWithFrame:CGRectMake(i*1024, 0, temp.size.width, temp.size.height)];
svHor.delegate=self;
svHor.contentSize=CGSizeMake(temp.size.width, temp.size.height);
UIImageView *imageHor=[[UIImageView alloc] initWithFrame:CGRectMake(0, 0, temp.size.width, temp.size.height)];
imageHor.image=temp;
imageHor.tag=2000;
[svVert addSubview:imageVert];
[svHor addSubview:imageHor];
[verticalScroll addSubview:svVert];
[horizontalScroll addSubview:svHor];
//fr=CGRectMake(0, 0, 768, 1024);
//[verticalScroll addSubview:imageVert];
// [horizontalScroll addSubview:imageHor];
}
//verticalScroll.delegate=self;
// horizontalScroll.delegate=self;
ambiancesON=YES;
if(self.interfaceOrientation==UIInterfaceOrientationPortrait || self.interfaceOrientation==UIInterfaceOrientationPortraitUpsideDown)
{
[self.view addSubview:verticalScroll];
}
else if(self.interfaceOrientation==UIInterfaceOrientationLandscapeLeft || self.interfaceOrientation==UIInterfaceOrientationLandscapeRight)
{
[self.view addSubview:horizontalScroll];
}
所以現在我有變焦方法:
- (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView {
NSLog(@"Log log log");
NSLog(@"VIew? %@", [[scrollView subviews]objectAtIndex:0]);
return [[scrollView subviews]objectAtIndex:0];
}
變焦不會被調用((
