我使用此解决方案将导航栏添加到tabbarcontroller:How to use Navigation Controller inside of UITabBarController with Storyboard on Swift
但是我发现了一个问题,例如,在我使用...
else:
choice == ''
print('Nome inesistente')
newChoice = input('Do you need more information?')
#your code to handle new choice user entered.
将double funcB(double y, functionPointer funcA, double x){
return y + funcA(x);
}
...
for(double y = 0; y < 1; y += 0.1){
for(double x = 0; x <= y; x += 0.1){
printf("%f\n", funcB(y, pArray[0], x) );
printf("%f\n", funcB(y, pArray[1], x) );
}
}
传递给view A
之后,我在tabbarcontroller的self.navigationController!.pushViewController
中嵌入了导航是view A
中带箭头的后退按钮。问题是当我单击后退按钮时,从view B
到view B
的动画消失... view B
传递view A
sudenlly,动画为view B
view A
慢慢地,但动画不起作用,为什么?谢谢
