如何让不同变量重复一个动作？
ios
iphone
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];2019-07-17 19:17:35赞同 展开评论
