tableview偏移

tableview偏移

 

方法一:改变edgesForExtendedLayout

self.edgesForExtendedLayout = UIRectEdgeNone;

将edgesForExtendedLayout属性设置为UIRectEdgeNone,这样布局就是从导航栏下面开始了

方法二:导航栏半透明属性设置为NO

@property(nonatomic,assign,getter=isTranslucent) BOOL translucent NS_AVAILABLE_IOS(3_0) UI_APPEARANCE_SELECTOR; // Default is NO on iOS 6 and earlier. Always YES if barStyle is set to UIBarStyleBlackTranslucent

在iOS 6之前(包括iOS 6)translucent默认就是NO,在iOS 7就默认是YES了。

self.navigationController.navigationBar.translucent = NO;

将导航栏的半透明属性关闭掉,布局也是从导航栏下面开始了。

判断ios系统是不是7.0  

 if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0) {

        self.edgesForExtendedLayoutUIRectEdgeNone;

    }
