之前在網上找的側滑全屏側滑返回，發現會與頁面其他手勢沖突，自己做了一下修改，發現還是挺好用的，分享給大家。
這是自定義的NavigationController
#import "Navigation.h"
@interface Navigation ()
@property (nonatomic,strong)UIPanGestureRecognizer *pan;
@property (nonatomic,strong)UIScreenEdgePanGestureRecognizer *screenEdgeGesOut;
@end
@implementation Navigation

//? ? [bar setBarStyle:UIBarStyleBlack];
//? ? [bar setBackgroundColor:[UIColor whiteColor]];
//? ? [bar setBackgroundImage:[UIImage imageNamed:@"背景"] forBarMetrics:UIBarMetricsDefault];
? ? [barsetBarTintColor:[UIColor whiteColor]];//UIColorFromRGB(0xff386b)
