Screen Property - 1

分别在竖屏和横屏中输出视图控制器中的：Self.view Self.view.window UIScreen UIApplication的相关属性值：x y width height center Frame bounds值
注意：UIDevice没有任何关于屏幕尺寸的属性，所以不添加测试，因为要用到横屏竖屏，所以用Masonry下的autolayout来实现布局：
#import "Masonry.h"#import "LBSreenPropertyTestController.h"@interface LBSreenPropertyTestController ()@end@implementation LBSreenPropertyTestController- (void)viewDidLoad{    [super viewDidLoad];    [self.view setBackgroundColor:[UIColor whiteColor]];        /**     *  本例子分别输出view, window, UIScreen, UIApplication 等（有待补充,  UIDevice无任何尺寸相关属性，只有方向）     *  的x y width height center bounds frame 值     */    UIButton* button0 = [UIButton buttonWithType:UIButtonTypeCustom];    [button0 setBackgroundColor:[UIColor redColor]];    [button0 setTitle:@"0击" forState:UIControlStateNormal];    [button0 addTarget:self action:@selector(buttonClicked:)      forControlEvents:UIControlEventTouchUpInside];

效果分别如下：
竖屏：
横屏：
