iOS让controller具有右滑pop的效果

ios让controller具有右滑pop的效果，首先要有navigationcontroller,在navigationcontroller的viewdidload方法里添加下面的代码

nsobject *targetobjc = [[self.interactivepopgesturerecognizer valueforkey:@"_targets"] firstobject];
    nsobject *target = [targetobjc valueforkey:@"target"];
    uipangesturerecognizer *pan = [[uipangesturerecognizer alloc] initwithtarget:target action:@selector(handlenavigationtransition:)];
    [self.view addgesturerecognizer:pan];

思路是利用runtime打印出uigesturerecognizer的属性，找到target存放的位置，继而找到self.interactivepopgesturerecognizer响应方法，重新创建一个平移手势加入到view上，利用响应者链实现我们的右滑pop效果。
