iOS开发之--全局解决模态弹出不全屏展示问题

利用tuntime的特性，创建一个UIViewController的类别，然后再pch文件里面调用即可，代码如下：

.h

#import <UIKit/UIKit.h>

NS_ASSUME_NONNULL_BEGIN

@interface UIViewController (SKPVCModel)

@end

NS_ASSUME_NONNULL_END

.m

#import "UIViewController SKPVCModel.h"
#import <objc/runtime.h>

@implementation UIViewController (SKPVCModel)

 (void)load{
       Method m1 = class_getInstanceMethod([self class], @selector(presentViewController:animated:completion:));
       Method m2 = class_getInstanceMethod([self class], @selector(skp_presentViewController:animated:completion:));
       method_exchangeImplementations(m1, m2);
}

- (void)skp_presentViewController:(UIViewController *)viewControllerToPresent animated: (BOOL)flag completion:(void (^ __nullable)(void))completion{
    viewControllerToPresent.modalPresentationStyle =  UIModalPresentationFullScreen;
    [self skp_presentViewController:viewControllerToPresent animated:flag completion:completion];
}

@end

这样的话，就可以了!

仅做记录！
