ios - 设置 UIImageView.frame 偶尔会导致 EXC_BAD_ACCESS

Question

我得到一个 EXC_BAD_ACCESS。我已经尝试了所有有关不良访问的建议，但没有运气。我知道这是我设置 UIImageView 框架时造成的。

这是代码...

_backImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"cardback_brothers_royal"]];
CGRect imageFrame = _backImageView.frame;
imageFrame.origin.x = -9;
imageFrame.origin.y = -9;
imageFrame.size.width = 151;
imageFrame.size.height = 225;
_backImageView.frame = imageFrame;

总是尝试像这样设置你的 ImageView 框架： YourImageView.frame = CGRectMake(x_position,y_position,width,height);
