CALayer NAN 使用自定义 UItableviewCell 删除 UITableView 的部分

嗨,我不知道在哪里进一步查看,我完全陷入困境:

场景:当我离开视图的编辑模式时,我删除了表格的行和部分。 该表格由不同的自定义单元格组成,这些单元格在进入或离开时有动画 编辑模式。

问题:有时,我不知道什么时候,我无法重现它,应用程序崩溃并显示“ CALayerInvalidGeometry',原因:'CALayer 位置包含 NaN:[nan 2.03571e-10]”错误消息。

我现在查找了几个小时,但找不到错误,因此我提供了更多代码,也许有人知道它发生在哪里:

我调用 tis 方法将表的编辑模式保留在其中 setupDetailEditMode 被调用

- (void)setEditing:(BOOL)editing animated:(BOOL)animated {


if(editing)
{..}
else{

        tableShowEditMode = NO;
    [self setupDetailEditMode];

    [self createPersonTableHeader];
    [self clearAllEmptyFieldsFromArray];
        [self saveUserProfile];

        [super setEditing:editing animated:animated];
        [profileTable setEditing:editing animated:YES];
......}

此代码是我删除部分的位置....某些部分仍然有行,这没有问题,因为它们将通过删除以下部分来删除。函数它崩溃了最后一行:

part of function **setupDetailEditMode**:
   //Phone Section
    if(removedRowsPhone)

    {
        if(app.isitUserProfile.isitPhone.count == 0)
            [sectionOperationIndexSet addIndex:sectionWorked];

        sectionWorked++;
    }

    //Email Section 
    if(removedRowsEmail)
    {
        if(app.isitUserProfile.isitEmail.count == 0)
            [sectionOperationIndexSet addIndex:sectionWorked];

        sectionWorked++;
    }



    //update table data structur
    [self buildCurrentTableStructure];

    //delete sections <<<<<**here will crash the app sometimes**
    [profileTable deleteSections:sectionOperationIndexSet withRowAnimation:UITableViewRowAnimationFade]; 

我添加了一个我使用的随机自定义单元格,也许有一些错误导致了layoutsubviews崩溃:

- (void) layoutSubviews {


    [super layoutSubviews];

    if (self.editing)
    {
        primaryField.enabled = YES;

        // (self.editing && !self.showingDeleteConfirmation)
        star1Img.frame = CGRectMake(87.0,30.0,20.0, 20.0);
        star2Img.frame = CGRectMake(111.0,30.0,20.0, 20.0);
        star3Img.frame = CGRectMake(135.0,30.0,20.0, 20.0);
        star4Img.frame = CGRectMake(159.0,30.0,20.0, 20.0);
        star5Img.frame = CGRectMake(183.0,30.0,20.0, 20.0);

        //primaryLabel.frame = CGRectMake(primaryLabel.frame.origin.x, 8.0,180.0 , 17.0);
        primaryField.frame = CGRectMake(primaryField.frame.origin.x, 8.0,180.0 , 17.0);
        secondaryLabel.frame = CGRectMake(secondaryLabel.frame.origin.x,18.0, 65.0 , 21.0);

    }
    else
    {
        primaryField.enabled = NO;

        star1Img.frame = CGRectMake(29.0,27.0,10.0, 10.0);
        star2Img.frame = CGRectMake(39.0,27.0,10.0, 10.0);
        star3Img.frame = CGRectMake(49.0,27.0,10.0, 10.0);
        star4Img.frame = CGRectMake(59.0,27.0,10.0, 10.0);
        star5Img.frame = CGRectMake(69.0,27.0,10.0, 10.0);

        primaryField.frame = CGRectMake(primaryField.frame.origin.x, 14.0,213.0 , 17.0);
        secondaryLabel.frame = CGRectMake(14.0,6.0, 65.0 , 21.0);
    }

} // layoutSubviews*/


- (void) setStarRating:(int) rating
{

    if(rating>=1)
        [star1Img setImage:[UIImage imageNamed:@"goldstar20.png"]];
......}

我很沮丧atm,因为我找不到这个错误,它会如果有人有提示或发现错误,请非常友善,谢谢

Hi i dont know where to look further im totally stuck:

Scenario: When i leave edit mode of my view i delete rows and sections of my table.
The table consits of different custom cells which have animation when entering or leaving
editmode.

Problem: Sometimes and i dont know when, i cant reproduce it, the app crashes with a "
CALayerInvalidGeometry', reason: 'CALayer position contains NaN: [nan 2.03571e-10]" error message.

I looked for hours now but i cant find the error therefor i provide some more code maybe anyone knows where it happens:

I call tis method to leave edit mode of the table in it setupDetailEditMode gets called.

- (void)setEditing:(BOOL)editing animated:(BOOL)animated {


if(editing)
{..}
else{

        tableShowEditMode = NO;
    [self setupDetailEditMode];

    [self createPersonTableHeader];
    [self clearAllEmptyFieldsFromArray];
        [self saveUserProfile];

        [super setEditing:editing animated:animated];
        [profileTable setEditing:editing animated:YES];
......}

This code is where i delete sections.... some of the sections still have rows which is no problem cause they will be deleted by deleting the section in the following function it crashes last line:

part of function **setupDetailEditMode**:
   //Phone Section
    if(removedRowsPhone)

    {
        if(app.isitUserProfile.isitPhone.count == 0)
            [sectionOperationIndexSet addIndex:sectionWorked];

        sectionWorked++;
    }

    //Email Section 
    if(removedRowsEmail)
    {
        if(app.isitUserProfile.isitEmail.count == 0)
            [sectionOperationIndexSet addIndex:sectionWorked];

        sectionWorked++;
    }



    //update table data structur
    [self buildCurrentTableStructure];

    //delete sections <<<<<**here will crash the app sometimes**
    [profileTable deleteSections:sectionOperationIndexSet withRowAnimation:UITableViewRowAnimationFade]; 

I add a random custom cell i use maybe there is something wrong that causes the crash in layoutsubviews:

- (void) layoutSubviews {


    [super layoutSubviews];

    if (self.editing)
    {
        primaryField.enabled = YES;

        // (self.editing && !self.showingDeleteConfirmation)
        star1Img.frame = CGRectMake(87.0,30.0,20.0, 20.0);
        star2Img.frame = CGRectMake(111.0,30.0,20.0, 20.0);
        star3Img.frame = CGRectMake(135.0,30.0,20.0, 20.0);
        star4Img.frame = CGRectMake(159.0,30.0,20.0, 20.0);
        star5Img.frame = CGRectMake(183.0,30.0,20.0, 20.0);

        //primaryLabel.frame = CGRectMake(primaryLabel.frame.origin.x, 8.0,180.0 , 17.0);
        primaryField.frame = CGRectMake(primaryField.frame.origin.x, 8.0,180.0 , 17.0);
        secondaryLabel.frame = CGRectMake(secondaryLabel.frame.origin.x,18.0, 65.0 , 21.0);

    }
    else
    {
        primaryField.enabled = NO;

        star1Img.frame = CGRectMake(29.0,27.0,10.0, 10.0);
        star2Img.frame = CGRectMake(39.0,27.0,10.0, 10.0);
        star3Img.frame = CGRectMake(49.0,27.0,10.0, 10.0);
        star4Img.frame = CGRectMake(59.0,27.0,10.0, 10.0);
        star5Img.frame = CGRectMake(69.0,27.0,10.0, 10.0);

        primaryField.frame = CGRectMake(primaryField.frame.origin.x, 14.0,213.0 , 17.0);
        secondaryLabel.frame = CGRectMake(14.0,6.0, 65.0 , 21.0);
    }

} // layoutSubviews*/


- (void) setStarRating:(int) rating
{

    if(rating>=1)
        [star1Img setImage:[UIImage imageNamed:@"goldstar20.png"]];
......}

I am very frustrated atm because i cant find this bug it would be very niice if anyone has a hint or find the bug. Anything will help. Thanks

我没有仔细查看你的代码,但我曾经有过类似的经历。有一个视图已发布,但确实想再次绘制 - 基本上是一个保留的东西。即使通过探查器也很难找到或理解。您应该使用探查器检查是否有任何地方泄漏。

I haven't looked through your code very much, but I had something similar once. There was a view that got released but did want to be painted again - basically a retain thing. Hard to find - or understand - even via profiler. You should check with the profiler if there is a leak anywhere.
