Question

我有一个自定义单元格，其中包含标签和图像视图。标签和图像视图根据条件显示。滚动uitableview时，我的自定义单元格奇怪。有一个实例，当我滚动一个标签和imageview时，标签和图像视图会显示，但是当我滚动回到图像视图并标记一个标签并且图像视图将消失时，有时它会重叠另一个图像视图和标签。这是我到目前为止所做的：

cabox@box-codeanywhere:~/workspace/PEP$ python ./dev_scrapers/jordan.py

我仍然得到相同的结果。我读了另一个解决方案，并在customcell.m文件中移动了我的计算。这是在 layoutSubviews 方法中。

static NSString *simpleTableIdentifier = @"JobDetailCell";
MTJobDetailCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier forIndexPath:indexPath];

if (cell == nil) {
    cell = [[MTJobDetailCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:simpleTableIdentifier];
}

这是我的cellForRowAtIndexPath代码：

NSInteger tempCount = [[NSUserDefaults standardUserDefaults] integerForKey:@"BenefitsCounter"];
NSDictionary *tempDictionary = [NSKeyedUnarchiver unarchiveObjectWithData:[[NSUserDefaults standardUserDefaults] objectForKey:@"IncentivesAndBenefits"]];
//TEST
NSLog(@"TEMP INT:%ld", (long)tempCount);
NSLog(@"TEMP ARRAY:%@", tempDictionary);

BOOL iFood = tempDictionary[@"food"][@"1"];
NSString* iFoodDescription = tempDictionary[@"food"][@"1"];
BOOL iCommission = tempDictionary[@"commission"][@"1"];
NSString* iCommissionDescription = tempDictionary[@"commission"][@"1"];
BOOL iUniform = tempDictionary[@"uniform"][@"1"];
NSString* iUniformDescription = tempDictionary[@"uniform"][@"1"];
BOOL iTransport = tempDictionary[@"transport"][@"1"];
NSString* iTransportDescription = tempDictionary[@"transport"][@"1"];
BOOL iExtras = tempDictionary[@"extras"][@"1"];
NSString* iExtrasDescription = tempDictionary[@"extras"][@"1"];

//MARK: POSITION labels and imageviews
int img_x = kImgStart_x;
int img_w = kImgStart_w;
int img_h = kImgStart_h;

//result value positions
int lbl_x = kLblStart_x;
int lbl_y = kLblStart_y;
int lbl_w = kLblStart_w;

if(tempCount == 1)
{
    if(iCommission)
    {
        //decrement

我的代码在iOS 8中完美运行。我真的很困惑为什么它在iOS 7中不起作用。自上周以来，我一直在努力解决这个问题。有人可以帮助我。

你可以尝试下面的代码 -

在

之后写下面的代码

if (cell == nil) {
    cell = [[MTJobDetailCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:simpleTableIdentifier];
}

for(UIView *view in cell.contentView.subviews){  
        if ([view isKindOfClass:[UIView class]]) {  
            [view removeFromSuperview];   
        }
    }

和

cell.clipsToBounds = YES;

添加所有UIlabel和UIImage，如下所示

[cell.contentView addSubview:myLabel] ;

标签和图像视图奇怪地表现在iOS7中的自定义单元格中
