ios5和ios6横竖屏支持及ipad和iphone设备的判断
ios5和ios6横竖屏支持及ipad和iphone设备的判断

判断是ipad还是iphone设备。此定义在PayViewControllerDemo-Prefix.pch

定义如下：

@interfaceViewController ()

之后需要在top-most controller中来控制方向问题。

if ([[UIDevicecurrentDevice]systemVersion].floatValue >= 6.0)

{

//判断设备当前的方向，然后重新布局不同方向的操作。

UIInterfaceOrientation currentOrientation = [[UIApplicationsharedApplication] statusBarOrientation];

if (currentOrientation ==UIInterfaceOrientationPortrait || currentOrientation == UIInterfaceOrientationPortraitUpsideDown)

{

if (isPad ==iPad)

{

drawViewipad.frame =CGRectMake(200, 150, 412, 120);

consumeBtnipd.frame =CGRectMake(768/2-280/2,550, 280, 50);

}

else if (isPad ==iPhone)

{

drawViewihone.frame =CGRectMake(85, 50,170, 60);

consumeBtnipone.frame =CGRectMake(90, 200,140, 40);

}

}

if (currentOrientation ==UIInterfaceOrientationLandscapeLeft || currentOrientation ==UIInterfaceOrientationLandscapeRight)

{

if (isPad ==iPad)

{

drawViewipad.frame =CGRectMake(306, 150, 412, 120);

consumeBtnipd.frame =CGRectMake(1024/2-280/2,550, 280, 50);

}

else if (isPad ==iPhone)

{

drawViewihone.frame =CGRectMake(155, 50, 170, 60);

consumeBtnipone.frame =CGRectMake(170, 200, 140, 40);

}

}

}

returnUIInterfaceOrientationMaskAll;

}

这样就能控制不同方向的任何操作和界面布局了。
