The Autoresizingmask property of UIView

Today when the album list, found some Uitableviewcontroller properties bad memory, and then looked for some information. Make a backup.

There is a Autoresizingmask property in UIView, which corresponds to the value of an enumeration (as follows), which means that the position of the child control and the parent control is automatically adjusted to a height of width.

enum{Uiviewautoresizingnone=0, Uiviewautoresizingflexibleleftmargin=1<<0, Uiviewautoresizingflexiblewidth=1<<1, Uiviewautoresizingflexiblerightmargin=1<<2, Uiviewautoresizingflexibletopmargin=1<<3, Uiviewautoresizingflexibleheight=1<<4, Uiviewautoresizingflexiblebottommargin=1<<5};

Uiviewautoresizingnone is not automatically adjusted, the control is not changed relative to the parent view coordinate value.
Uiviewautoresizingflexibleleftmargin automatically adjusts the distance to the left of the superview, ensuring that the distance to the right of the Superview is constant.
Uiviewautoresizingflexiblerightmargin automatically adjusts to the right distance from the Superview to ensure that the distance to the left of the Superview is constant.
The uiviewautoresizingflexibletopmargin automatically adjusts the distance from the top of the Superview to ensure that the distance from the bottom of the Superview is constant.
Uiviewautoresizingflexiblebottommargin automatically adjusts the distance from the bottom of the Superview, that is, the distance from the top of the Superview is constant.
Uiviewautoresizingflexiblewidth automatically adjusts its width to ensure that the distance to the left and right of the Superview is constant, and the width of the control changes proportionally with the width of the parent view.

For example: Label width is 100 and screen width is 320. When the screen width is 480, the label width changes to 100*480/320
Uiviewautoresizingflexibleheight automatically adjusts its height to ensure that the distance from the top and bottom of the Superview is constant.

Uiviewautoresizingflexibleleftmargin | Uiviewautoresizingflexiblerightmargin automatically adjusts the distance to the left of the superview to ensure that the distance to the left and to the right is the same as the distance from the left and right.

For example: CGRectMake (50, 100, 200, 40)]; When the width of the screen is 320,x 50;

When the screen width is 480, the LABELX coordinates become 50*480/320. Control coordinates change to CGRectMake (75, 100, 200, 40)];

The original distance is 20, 30, the adjusted distance should be 68,102, that is, 68/20=102/30.

Other combinations are similar.
