关于新的获取屏幕高度，状态栏尺寸，标签栏尺寸的获取方法，找了多个资料和文章，其方法总结如下

App尺寸，去掉状态栏

1
2
CGRect r = [ UIScreen mainScreen ].applicationFrame;
NSLog(@"r.height = %f,r.width = %f,r.x = %f,r.y = %f",r.size.height,r.size.width,r.origin.x,r.origin.y);

gowhich得到的结果如下：

屏幕尺寸

CGRect rx = [UIScreen mainScreen].bounds;
NSLog(@"rx.height = %f,rx.width = %f,rx.x = %f,rx.y = %f",rx.size.height,rx.size.width,rx.origin.x,rx.origin.y);

得到的结果如下：

2013-11-28 12:09:22.189 寻艺[49308:70b] rx.height = 568.000000,rx.width = 320.000000,rx.x = 0.000000,rx.y = 0.000000

状态栏尺寸

CGRect rect  = [[UIApplication sharedApplication] statusBarFrame];
NSLog(@"rect.height = %f,rect.width = %f,rect.x = %f,rect.y = %f",rect.size.height,rect.size.width,rect.origin.x,rect.origin.y);

得到的结果如下：

2013-11-28 12:14:18.972 寻艺[49617:70b] rect.height = 20.000000,rect.width = 320.000000,rect.x = 0.000000,rect.y = 0.000000

CGRect rect = [[UIScreen mainScreen] bounds];

CGSize size = rect.size;

CGFloat width = size.width;

CGFloat height = size.height;

另外，设计UI的时候，注意用户最小的触控面积。有2种说法

44*44 好像是来自sdk

64*64 来自standford讲义
