怎么样让不同变量重复一个动作？

Question

举例说明我想实现的，比如我有十个变量（整数值）以及变量的值，一个字符串。

然后代码中是判断云的数量决定天气状况：

 if (hour1cloud <= 5) {
            hour1weather = @"Clear";
        }
        if (5 < hour1cloud <= 25) {
            hour1weather = @"Mostly Clear";
        }
        if (25 < hour1cloud <= 50) {
            hour1weather = @"Partly Cloudy";
        }
        if (50 < hour1cloud <= 83) {
            hour1weather = @"Mostly Cloudy";
        }
        if (83 < hour1cloud <= 105) {
            hour1weather = @"Overcast";
        }

然后 hour2cloud, hour3cloud, hour4cloud分别对应hour2weather, hour3weather,等。当我输入hour1cloud获取hour1weather的值，能不能对所有组都变成通用方法？

方法如下：

- (NSString*)weatherStringFromCloud:(int)cloud {
    NSString *weather;
    if (cloud <= 5) {
        weather = @"Clear";
    } else if (cloud <= 25) {
        weather = @"Mostly Clear";
    } else if (cloud <= 50) {
        weather = @"Partly Cloudy";
    } else if (cloud <= 83) {
        weather = @"Mostly Cloudy";
    } else if (cloud <= 105) {
        weather = @"Overcast";
    } else {
        weather = nil;
    }
    return weather;
}

然后用不同变量调用：

hour1weather = [self weatherStringFromCloud:hour1cloud];
hour2weather = [self weatherStringFromCloud:hour2cloud];
hour3weather = [self weatherStringFromCloud:hour3cloud];
hour4weather = [self weatherStringFromCloud:hour4cloud];
