我有两个 UITextView 的“autoresizingMask”问题。当我调整两个 UITextViews 的大小时，第一个重叠在第二个之上。我附上了一张图片来解释这个问题。
谢谢！
更新：我把revenant代码
[UIView]
self.autoresizesSubviews = YES;
// Configure title label
_titleLabel = [[UILabel alloc] init];
_titleLabel.frame = CGRectMake(4.0, 4.0, self.bounds.size.width - 8.0, 33.0);
_titleLabel.backgroundColor = APP_COLOR(1.0);
_titleLabel.font = FONT_LATO_BOLD(18.0);
_titleLabel.textColor = [UIColor whiteColor];
_titleLabel.textAlignment = UITextAlignmentCenter;
[self addSubview:_titleLabel];
// Question textView
_questionTextView = [[UITextView alloc] initWithFrame:CGRectMake(0.0, 0.0, CGRectGetWidth(_titleLabel.bounds), (usableHeight / 2.0) - 4.0)];
_questionTextView.layer.cornerRadius = 8.0;
_questionTextView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleBottomMargin;
[self addSubview:_questionTextView];
// Answer textView
_answerTextView = [[UITextView alloc] initWithFrame:CGRectMake(CGRectGetMinX(_questionTextView.frame), CGRectGetMaxY(_questionTextView.frame) + 8.0, CGRectGetWidth(_questionTextView.bounds), (usableHeight / 2.0) - 4.0)];
_answerTextView.layer.cornerRadius = 8.0;
_answerTextView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleTopMargin;
[self addSubview:_answerTextView];
