更新版本号判断方法
- 考虑到上架更新版本时间不固定，有可能出现App上架而后台请求的版本号还未更新，出现App当前版本比后台的最新版本还高德情况
/**判断版本号，是否需要更新，当需要更新返回YES*/
+(BOOL)BSGWithAppVersion:(NSString *)appVersion LastVersion:(NSString *)lastVersion
{
//应用版本
NSArray * appVArray = [appVersion componentsSeparatedByString:@"."];
//最新版本
NSArray * lastVArray = [lastVersion componentsSeparatedByString:@"."];
NSInteger count = appVArray.count;
//判断是否是最新
BOOL isLastVersion = YES;
NSInteger appVNum;
NSInteger lastVNum;
for (int i = 0; i < count; i++) {
appVNum = [appVArray[i] integerValue];
lastVNum = [lastVArray[i] integerValue];
if (appVNum < lastVNum) {
isLastVersion = NO;
break;
}
}
return isLastVersion;
}
使用方法：
//应用版本
NSString * appVersion = @"3.9.78";
//后台保存最新版本
NSString * lastVersion = @"3.9.786";
BOOL isLast = [BSGCommonMethod BSGWithAppVersion:appVersion LastVersion:lastVersion];
