@实现UIView控制器（当前KBIook）

• （空隙）荷载{

[UIViewController ff_swizzleInstanceMethodWithSrcClass:[UIViewController class] srcSel:@selector(presentViewController:animated:completion:) swizzledSel:@selector(cr_presentViewController:animated:completion:)];

}

• （void）cr_presentViewController：（UIViewController *）视图控制器到当前动画：（BOOL）标志完成：（void（^）（void））完成{

if (self.presentedViewController) {

}else{
    [self cr_presentViewController:viewControllerToPresent animated:flag completion:completion];

//交换两个对象方法的实现

• （无效）ff_swizzleInstanceMethodWithSrcClass：（类）源类源选择：（选择）源选择混合选择：（选择）混合选择{

//Add a layer of protection measures. If the method is added successfully, it means that the method does not exist in this class, but exists in the parent class, and the method of the parent class cannot be exchanged, otherwise the method will crash when the parent class object calls the method; Adding failure indicates that the method exists in this class
