在程序中看到这样代码 self.autoresizingMask = UIViewAutoresizingFlexibleWidth;
在网上查了查,博主讲的比较清楚,此处做一个保留
UIView中有个属性是autoresizingMask,该属性是用来控制控件的自适应。
UIViewAutoresizingNone
UIViewAutoresizingFlexibleLeftMargin
UIViewAutoresizingFlexibleWidth
UIViewAutoresizingFlexibleRightMargin
UIViewAutoresizingFlexibleTopMargin
UIViewAutoresizingFlexibleHeight
UIViewAutoresizingFlexibleBottomMargin
UIViewAutoresizingNone:控件相对于父视图坐标值不变;
UIViewAutoresizingFlexibleWidth:控件的宽度随着父视图的宽度按比例改变;
例如:label宽度为100,屏幕的宽度为320。当屏幕宽度为480时,label宽度变为100*480/320
UIViewAutoresizingFlexibleHeight:与UIViewAutoresizingFlexibleWidth相同
UIViewAutoresizingFlexibleLeftMargin:到屏幕左边的距离随着父视图的宽度按比例改变;
例如:CGRectMake(50, 100, 200, 40)]; 当屏幕的宽度为320,x为50;当屏幕宽度为480时,labelx坐标变为50*480/320。
控件坐标变为 CGRectMake(75, 100, 200, 40)];
UIViewAutoresizingFlexibleRightMargin
UIViewAutoresizingFlexibleTopMargin
UIViewAutoresizingFlexibleBottomMargin
UIViewAutoresizingFlexibleLeftMargin类似
