UIScrollView以编程方式自动调整掩码

Question

我正在尝试以编程方式调整UIScrollView的大小，以便在iPhone 5上调整高度，我通过Storyboard实现了这一点，但是想以编程方式进行，

我已经使用以下内容来创建我的UIScrollView，但似乎无法改变尺寸以适应iPhone 5，因为我最初设置较小的iPhone的帧大小？

scroll = [[UIScrollView alloc] initWithFrame:CGRectMake(15, 80, 289, 153)];
scroll.autoresizesSubviews = YES;
scroll.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;

Answer 1

试试这个，

scroll = [[UIScrollView alloc] initWithFrame:CGRectMake(15, 80, 289, 153)];
scroll.autoresizingMask = (UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin);
