较大 uiscroll 中的嵌套 uiscroll 需要在缩放时在它们离开屏幕时重置缩放级别。当滚动结束但没有运气时，我正在尝试重置所有这些。有任何想法吗？
myScrollview = [[UIScrollView alloc]initWithFrame:CGRectMake(0, 0, self.view.frame.size.width,self.view.frame.size.height)];
myScrollview.pagingEnabled = YES;
myScrollview.scrollEnabled =YES;
myScrollview.clipsToBounds = NO;
myScrollview.indicatorStyle = UIScrollViewIndicatorStyleWhite;
myScrollview.showsHorizontalScrollIndicator = YES;
myScrollview.backgroundColor = [UIColor blackColor];
myScrollview.delegate = self;
NSInteger viewcount=4;
NSArray *images = [NSArray arrayWithObjects:[UIImage imageNamed:@"01.png"],[UIImage imageNamed:@"02.png"],[UIImage imageNamed:@"03.png"],[UIImage imageNamed:@"04.png"],nil];
for (int i = 0; i <viewcount; i++)
{
CGFloat x = i * self.view.frame.size.width;
subView = [[UIScrollView alloc]initWithFrame:CGRectMake(x, 0, self.view.frame.size.width, self.view.frame.size.height)];
[subView setBackgroundColor:[UIColor blackColor]];
[subView setCanCancelContentTouches:NO];
subView.clipsToBounds = NO; // default is NO, we want to restrict drawing within our scrollview
subView.indicatorStyle = UIScrollViewIndicatorStyleWhite;
aImageView = [[UIImageView alloc ] initWithImage:[images objectAtIndex:i]];
[self.aImageView setTag:viewcount];
[subView addSubview:aImageView];
[subView setContentSize:CGSizeMake(aImageView.frame.size.width, subView.frame.size.height)];
subView.minimumZoomScale = 1;
subView.maximumZoomScale = 3;
subView.delegate = self;
[subView setScrollEnabled:YES];
subView.contentSize = aImageView.frame.size;
[myScrollview addSubview:subView];
}
myScrollview.contentSize = CGSizeMake(self.view.frame.size.width*viewcount,self.view.frame.size.height);
[self.view addSubview:myScrollview];
}
-(UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView {
NSLog (@"test");
UIView * view = nil;
view = [subView viewWithTag:0];
//return view;
return [scrollView.subviews objectAtIndex:0];
}
-(void)scrollViewDidScroll:(UIScrollView *)scrollView {
NSLog(@"Did scroll");
[self resetImageZoom];
}
-(void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView { = NSLog(@"Did end decal");
[self resetImageZoom];
}
-(void)resetImageZoom { NSLog(@"重置任何图像缩放");
for(UIView *view in [myScrollview subviews]) {
//if([view isKindOfClass:[UIScrollView class]]) {
//[(UIScrollView*)view setZoomScale:1.0 animated:NO];
//}
view.transform = CGAffineTransformIdentity;
}
