CustomUITableViewCell不显示所有模拟器上的子视图

Question

我有自定义单元格的tableView。自定义单元格有两个按钮。我遇到的问题是单元格中的按钮没有显示在所有模拟器上，实际上它们只显示在iphone5和ipad2模拟器上，而不显示在其他模拟器上。任何人都有线索？

附加截图（iphone5＆amp; iphone5S）和customCell代码。

@interface AWSCameraProfileTableViewCell : UITableViewCell
    @property (weak, nonatomic) IBOutlet UIButton *videoButton;
    @property (weak, nonatomic) IBOutlet UIButton *uploadToCloudButton;
@end

@synthesize videoButton,uploadToCloudButton;

//  to set up our cell from the storyboard.
- (id) initWithCoder:(NSCoder *)aDecoder
{
self = [super initWithCoder:aDecoder];

if (self)
{
    // Initialization code
    self.cellID = 1;//cInvalidCellID;

    // Install the custom background
    self.tableViewCellBackgroundView = [TableViewCellBackgroundView newTableViewCellBackgroundViewWithFrame:self.frame

Answer 1

您使用self.contentView.bounds.size的绝对值放置这些子视图。你不能这样做，因为在这段代码运行时，单元格还没有给出它的实际大小。因此，您最终会关闭屏幕上的按钮。

您最好的选择是使用autolayout定位子视图。这样，无论它的大小如何，您都可以将它们固定在单元格的右边缘。
