我创建了一个子类，UITableViewCell因为我想明确设置imageView帧大小，而不管我实际给它的图像大小。

话虽如此，当我tableView加载时，一切似乎在一瞬间发生了变化。图像稍微变大，titleLabel和detailLabel都移到更靠近图像的位置。我在我的子类中做错了什么吗？

- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
    self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
    if (self) {
        // Selected View
        self.selectedBackgroundView = [[UIView alloc] initWithFrame:self.frame];
        self.selectedBackgroundView.backgroundColor = RGB(233, 233, 233);

        // Text Label
        self.textLabel.textColor = [UIColor darkGrayColor];
        self.textLabel.opaque = YES;
        self.textLabel.highlightedTextColor = self.textLabel.textColor;

        // Detail
        self.detailTextLabel.font = [UIFont systemFontOfSize:12.0];
        self.detailTextLabel.numberOfLines = 3;
        self.detailTextLabel.opaque = YES;
        self.detailTextLabel.highlightedTextColor = self.detailTextLabel.textColor;

        // Cell
        self.opaque = YES;
    }
    return self;
}


- (void)setSelected:(BOOL)selected animated:(BOOL)animated
{
    [super setSelected:selected animated:animated];

    // Configure the view for the selected state
}


- (void)layoutSubviews {
    [super layoutSubviews];

    float desiredWidth = 70;
    float desiredHeight = 70;
    float leftMargin = 5;
    float topMargin = 5;

    float w=self.imageView.frame.size.width;
    self.imageView.contentMode = UIViewContentModeScaleAspectFill;
    self.imageView.clipsToBounds = YES;
    if (w>desiredWidth) {
        float widthSub = w - desiredWidth;
        self.imageView.frame = CGRectMake(leftMargin,topMargin,desiredWidth,desiredHeight);
        self.textLabel.frame = CGRectMake(self.textLabel.frame.origin.x-widthSub,self.textLabel.frame.origin.y,self.textLabel.frame.size.width+widthSub,self.textLabel.frame.size.height);
        self.detailTextLabel.frame = CGRectMake(self.detailTextLabel.frame.origin.x-widthSub,self.detailTextLabel.frame.origin.y,self.detailTextLabel.frame.size.width+widthSub,self.detailTextLabel.frame.size.height);

    }
}

我看到你在做

self.selectedBackgroundView = [[UIView alloc] initWithFrame:self.frame];

我真的觉得应该

self.selectedBackgroundView = [[UIView alloc] initWithFrame:self.bounds];

因为 self.selectedBackgroundView 是基于父视图坐标系定位的
