Ios 当ScrollView设置为PaginEnabled为YES时，点击ScrollView调用“ScrollView将开始加速”

当我点击ScrollView时，它调用方法

ScrollView将开始加速

和

ScrollViewDiEndDeceling

，即使在

ScrollView的

设置为

PaginEnabled

后也是如此

我有

滚动视图

和

子视图

，并试图根据

子视图

设置

contentOffset

。但它不起作用

这是我的密码：

self.myScrollView.frame = CGRectMake(0, 0, pageWidth, pageHeight);
self.myScrollView.contentSize = CGSizeMake(pageWidth * self.contentViewControllers.count, pageHeight);

for (NSInteger i = 0; i < self.contentViewControllers.count; i++) {
    UILabel *label = [UILabel new];
    label.textColor = [UIColor whiteColor];
    label.textAlignment = NSTextAlignmentCenter;
    label.text = [NSString stringWithFormat:@"Page %ld",i];
    label.backgroundColor = [UIColor randomColor];
    label.frame = CGRectMake(i * pageWidth, 0, pageWidth, pageHeight);
    [self.myScrollView addSubview:label];
}

self.myScrollView.contentInset = UIEdgeInsetsMake(120, 0, 0, 0);
self.myScrollView.contentOffset = CGPointMake(0, - 120);
self.myScrollView.scrollIndicatorInsets = UIEdgeInsetsMake(120, 0, 0, 0);

- (UIScrollView *)myScrollView{
if (!_myScrollView) {
    _myScrollView = [[UIScrollView alloc] initWithFrame:CGRectZero];
    _myScrollView.backgroundColor = [UIColor blackColor];
    _myScrollView.pagingEnabled = YES;
    _myScrollView.directionalLockEnabled = YES;
    _myScrollView.delegate = self;
    //_myScrollView.delaysContentTouches = NO;
    //_myScrollView.scrollsToTop = NO;
}

return _myScrollView;
}

self.myScrollView.frame=CGRectMake（0，0，pageWidth，pageHeight）；
self.myScrollView.contentSize=CGSizeMake（pageWidth*self.contentViewControllers.count，pageHeight）；
对于（NSInteger i=0；i

当我点击

滚动视图

中的任何

子视图

时，它调用委托方法：

scrollViewWillBeginDecelerating

>

scrollViewDidScroll

>

scrollViewDidEndDecelerating

---

而

contentOffset

更改为

{0,0}

请按如下方式更新您的代码：

请在for循环之后设置contentSize

self.myScrollView.frame = CGRectMake(0, 0, pageWidth, pageHeight);

for (NSInteger i = 0; i < self.contentViewControllers.count; i++) {
    UILabel *label = [UILabel new];
    label.textColor = [UIColor whiteColor];
    label.textAlignment = NSTextAlignmentCenter;
    label.text = [NSString stringWithFormat:@"Page %ld",i];
    label.backgroundColor = [UIColor randomColor];
    label.frame = CGRectMake(i * pageWidth, 0, pageWidth, pageHeight);
    [self.myScrollView addSubview:label];
}

self.myScrollView.contentInset = UIEdgeInsetsMake(120, 0, 0, 0);
self.myScrollView.contentOffset = CGPointMake(0, - 120);
self.myScrollView.scrollIndicatorInsets = UIEdgeInsetsMake(120, 0, 0, 0);

self.myScrollView.contentSize = CGSizeMake(pageWidth * self.contentViewControllers.count, pageHeight);

- (UIScrollView *)myScrollView{
if (!_myScrollView) {
    _myScrollView = [[UIScrollView alloc] initWithFrame:CGRectZero];
    _myScrollView.backgroundColor = [UIColor blackColor];
    _myScrollView.pagingEnabled = YES;
    _myScrollView.directionalLockEnabled = YES;
    _myScrollView.delegate = self;
    //_myScrollView.delaysContentTouches = NO;
    //_myScrollView.scrollsToTop = NO;
}

return _myScrollView;
}

self.myScrollView.frame=CGRectMake（0，0，pageWidth，pageHeight）；
对于（NSInteger i=0；i
