感谢大佬给的解答
创建 UINavigationController+Main.h 文件
.h文件
#import
NS_ASSUME_NONNULL_BEGIN
@interfaceUINavigationController (Main)
@end
NS_ASSUME_NONNULL_END
.m文件
#import "UINavigationController+Main.h"
#import
@implementationUINavigationController (Main)
+ (void)load {
staticdispatch_once_tonceToken;
dispatch_once(&onceToken, ^{
MethodoriM =class_getInstanceMethod([selfclass],@selector(pushViewController:animated:));
MethodrepM =class_getInstanceMethod([selfclass],@selector(p_pushViewController:animated:));
method_exchangeImplementations(oriM, repM);
});
}
- (void)p_pushViewController:(UIViewController*)viewController animated:(BOOL)animated {
dispatch_async(dispatch_get_main_queue(), ^{
[selfp_pushViewController:viewControlleranimated:animated];
});
}
@end
其他的什么也不用动
