iOS7新特性适配

解决方法1：

导航栏设置为不透明

self.navigationController.navigationBar.translucent = NO;

页面会向下压缩如同iOS6向下压缩self.view的高一样

---------------------------------------------------------------------------------------------------------------------------------------

解决方法2：

设置不滚动

if ([[[UIDevice currentDevice]systemVersion]floatValue]>=7.0) {
　　self.automaticallyAdjustsScrollViewInsets = NO;
}

页面不会向下压缩
