之前在网上找的侧滑全屏侧滑返回，发现会与页面其他手势冲突，自己做了一下修改，发现还是挺好用的，分享给大家。
这是自定义的NavigationController
demo在这里
#import "Navigation.h"
@interface Navigation ()
@property (nonatomic,strong)UIPanGestureRecognizer *pan;
@property (nonatomic,strong)UIScreenEdgePanGestureRecognizer *screenEdgeGesOut;
@end
@implementation Navigation
+(void)initialize{
//要用appearance初始化
UINavigationBar *bar = [UINavigationBar appearance];
// [bar setBarStyle:UIBarStyleBlack];
// [bar setBackgroundColor:[UIColor whiteColor]];
// [bar setBackgroundImage:[UIImage imageNamed:@"背景"] forBarMetrics:UIBarMetricsDefault];
[barsetBarTintColor:[UIColor whiteColor]];//UIColorFromRGB(0xff386b)
bar.translucent=NO;
NSMutableDictionary *dic = [NSMutableDictionary dictionary];
dic[NSForegroundColorAttributeName] = [UIColor colorWithRed:62/255.f green:62/255.f blue:62/255.f alpha:1];//[UIColor whiteColor]
dic[NSFontAttributeName] = [UIFont systemFontOfSize:15 weight:0.3];// [UIFont fontWithName:@"HiraKakuProN-W6" size:15];
[barsetTitleTextAttributes:dic];
bar.barStyle = UIBarStyleDefault;// UIBarStyleBlack
// //设置item属性
// UIBarButtonItem *item = [UIBarButtonItem appearance];
// NSMutableDictionary *itemArrays = [NSMutableDictionary dictionary];
// itemArrays[NSFontAttributeName] = [UIFont systemFontOfSize:16];
// itemArrays[NSForegroundColorAttributeName] = UIColorFromRGB(0x323232);
// [item setTitleTextAttributes:itemArrays forState:UIControlStateNormal];
//
// NSMutableDictionary *itemDisAttrys = [NSMutableDictionary dictionary];
// itemDisAttrys[NSForegroundColorAttributeName] = [UIColor whiteColor];
// [item setTitleTextAttributes:itemDisAttrys forState:UIControlStateDisabled];
}
- (BOOL)gestureRecognizer:(UIGestureRecognizer*)gestureRecognizer shouldBeRequiredToFailByGestureRecognizer:(UIGestureRecognizer*)otherGestureRecognizer
{
return (self.topViewController !=[self.viewControllers firstObject]);
}
// 防止导航控制器只有一个rootViewcontroller时触发手势
- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer*)gestureRecognizer {
//解决与左滑手势冲突
