新手照书敲代码错误,关于CGAffineTransformIdentity在Xcode4.2下报错!
代码如下:-(void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)InterfaceOrientation duration:(NSTimeInterval)duration {
if(InterfaceOrientation == UIInterfaceOrientationPortrait)
{
self.view =self.portrait;
self.view.transform = CGAffineTransformIdentity;
self.view.transform =
CGAffineTransformMakeRotation(degreeToRadians(0));
self.view.bounds =CGRectMake(0.0, 0.0, 320.0, 460.0);
}
这方法里面使用的CGAffineTransformIdentity和CGAffineTransformMakeRotation报错,但是输入方法的时候还有提示,但是还是报如下错误?

看链接信息,是模拟器版本吧?看看模拟器支持吗
