Iphone 更改加载屏幕活动指示器的方向

如何更改代码,使视图相对于设备的方向发生变化
activityIndicator.autoresizingMask = (UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin);
希望这会有所帮助。试试,activityIndicator.autoresizingMask=(UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleWidth | UIViewAutoResizingFlexibleLeLeLeLeLeftMargin | UIViewAutoresizingFlexibleRightMargin);
if (self.interfaceOrientation == UIInterfaceOrientationLandscape ||self.interfaceOrientation == UIInterfaceOrientationPortrait) {
yourctivity.view.frame = CGRectMake(self.view.center, self.view.center, 30, 30);
}
