我正在动态添加一个自定义视图，我得到了这个异常
例外： ; 符号存根：getpid
ITMCustomView *cView = [[ITMCustomView alloc] initWithFrame:CGRectMake(187, 660, 400, 400)
andOrderedItem:@"dd"
andTag:self.tagNumber
withFoldArray:self.foldTypeArray
withRollArray:self.rollTypeArray];
cView.delegate = self;
//set properties of cView...like cView.txtName.text =@"John";
//self.scrollView.contentSize = CGRectMake(187, 660, 400, 400).size;
/*CGPoint scrollPoint = CGPointMake(0.0, (cView.frame.origin.y/800)*400);
[self.scrollView setContentOffset:scrollPoint animated:YES];
[self.scrollView addSubview:cView];
CGFloat scrollViewHeight = 0.0f;
for (UIView *view in self.scrollView.subviews)
{
scrollViewHeight += view.frame.size.height;
}
CGSize newSize = CGSizeMake(320,scrollViewHeight);
//CGRect newFrame = (CGRect){CGPointZero,newSize};
[self.scrollView setContentSize:newSize];
NSLog(@"750 the tag number is %d",self.tagNumber);
NSLog(@"the scroll view height is %f",scrollViewHeight);
self.currentCGRectLocation = cView.frame;*/
上面有很多代码，我在 /* */ 中评论过。在此之前我也有一行
//self.scrollView.contentSize = CGRectMake(187, 660, 400, 400).size;
如果我取消注释上面的行，它就会开始出现异常。我在我的应用程序中的另一个地方看到了这段代码。当我第一次启动应用程序时，会调用此代码并且它工作正常。现在我将记录保存在此屏幕-A 上并进行其他计算（基本上转到另一个屏幕-B）并返回此屏幕并检索保存的记录并显示它，只需将其显示在屏幕 A 上然后我得到这个例外。我注意到的是我对滚动视图所做的任何事情都给出了例外。如果我省略这条线
[self.scrollView addSubview:cView];
在评论之外，我可以看到自定义视图添加得非常好..但我失去了滚动..屏幕卡住了..所以我认为问题与滚动视图有关。如果您需要更多信息，请告诉我。谢谢..
编辑：改为这个..仍然不起作用。
