Summary of redirection methods between ios interfaces, and summary of ios page redirection
I have been in touch with ios for a while. By accident, our company's technical director and my mentor asked me, you know, there are several ways to jump between interfaces? I said two types, but they are also a bit vague, so I want to find a time to sum up. There is a saying that "the predecessors planted trees, and future generations enjoyed the coolness". Currently, as a cool-down person, I also hope to

Luogp1586 Sifang theorem and P1586 Sifang TheoremDescription
The square theorem is well known: any positive integer nn can be decomposed into a sum of squares of up to four integers. Example: 25 = 1 ^ {2} + 2 ^ {2} + 2 ^ {2} + 4 ^ {2} 25 = 12 + 22 + 22 + 42, of course there are other decomposition solutions, 25 = 4 ^ {2} + 3 ^ {2} 25 = 42 + 32 and 25 = 5 ^ {2} 25 = 52. The total number of solutions that can be decomposed by the given positive integer nn. Note: 25 = 4 ^ {2} + 3 ^ {2} 25 = 42 + 32

view controller object to the end of the array when it is in the stack. Removelastobject removes the View controller object at the end of the array when it is out of the stack.
The Navigationcontroller property, the attributes in the parent class, and the controllers in each stack, can be obtained by this property to obtain their own Uinavigationcontroller object.
The characteristics of the stack: Advanced after-out, LIFO first.
