在view controller中（比如viewDidLoad方法裡）新增：#define IOS7_OR_LATER ( [[[UIDevice currentDevice] systemVersion] compare:@"7.0"] != NSOrderedAscending ) #if __IPHONE_OS_VERSION_MAX_ALLOWED >= 70000 if ( IOS7_OR_LATER ) { self.edgesForExtendedLayout = UIRectEdgeNone; self.extendedLayoutIncludesOpaqueBars = NO; self.modalPresentationCapturesStatusBarAppearance = NO; }#endif // #if __IPHONE_OS_VERSION_MAX_ALLOWED >= 70000
