压缩成一个函数? [英] Compress this into a function?

问题描述

您好，我有以下代码，这些代码的确很长，如何将其压缩为函数?然后在其他工作日和一周中的课程中调用此函数?目前，我只是反复使用相同的代码，而只是替换变量(字符串).

Hi I have the following code which is really long of course, how can I compress this into a function? Then call this function with the other weekdays and lessons in the week? Currently Im just using the same code over and over just replacing the variables (which are strings).

//Allocate and add objects to monday week one.
    monArrayA = [[NSMutableArray alloc] init];
    [monArrayA addObject:@"Before School"];
    [monArrayA addObject:[NSString stringWithFormat:@"%@", monP1A]];
    [monArrayA addObject:[NSString stringWithFormat:@"%@", monP2A]];
    [monArrayA addObject:@"Break"];
    [monArrayA addObject:[NSString stringWithFormat:@"%@", monP3A]];
    [monArrayA addObject:[NSString stringWithFormat:@"%@", monP4A]];
    [monArrayA addObject:@"Lunch"];
    [monArrayA addObject:[NSString stringWithFormat:@"%@", monP5A]];
    [monArrayA addObject:[NSString stringWithFormat:@"%@", monP6A]];
    [monArrayA addObject:@"After School"];

    //Allocate and add objects to monday week two.
    monArrayB = [[NSMutableArray alloc] init];
    [monArrayB addObject:@"Before School"];
    [monArrayB addObject:[NSString stringWithFormat:@"%@", monP1B]];
    [monArrayB addObject:[NSString stringWithFormat:@"%@", monP2B]];
    [monArrayB addObject:@"Break"];
    [monArrayB addObject:[NSString stringWithFormat:@"%@", monP3B]];
    [monArrayB addObject:[NSString stringWithFormat:@"%@", monP4B]];
    [monArrayB addObject:@"Lunch"];
    [monArrayB addObject:[NSString stringWithFormat:@"%@", monP5B]];
    [monArrayB addObject:[NSString stringWithFormat:@"%@", monP6B]];
    [monArrayB addObject:@"After School"];

    //Allocate and add objects to tuesday week one.

推荐答案

尝试一下:

NSMutableArray* helper(id a, id b, id c, id d, id e, id f) {
    NSMutableArray* arr = [[NSMutableArray alloc] init];
    [arr addObject:@"Before School"];
    [arr addObject:[NSString stringWithFormat:@"%@", a]];
    [arr addObject:[NSString stringWithFormat:@"%@", b]];
    [arr addObject:@"Break"];
    [arr addObject:[NSString stringWithFormat:@"%@", c]];
    [arr addObject:[NSString stringWithFormat:@"%@", d]];
    [arr addObject:@"Lunch"];
    [arr addObject:[NSString stringWithFormat:@"%@", e]];
    [arr addObject:[NSString stringWithFormat:@"%@", f]];
    [arr addObject:@"After School"];
    return arr;
}

...

monArrayA = helper(monP1A, monP2A, monP3A, monP4A, monP5A, monP6A);
monArrayB = helper(monP1B, monP2B, monP3B, monP4B, monP5B, monP6B);

tueArrayA = helper(tueP1A, ...);
tueArrayB = helper(monP1B, ...);

...

如果您的对象位于数组而不是离散变量的集合中，则可能甚至可以将其压缩得更多.

You could probably condense it even more if your objects were in arrays instead of a constellation of discrete variables.
