//对外版本
#define APP_ShortVersion [NSBundle mainBundle].infoDictionary[@"CFBundleShortVersionString"]
//对内版本
#define APP_Verson [NSBundle mainBundle].infoDictionary[@"CFBundleVersion"]
对于iOS版本号的比较,首先对两个字段要了解,CFBundleShortVersionString是App Store所使用的版本号,也就是你在App Store里能看到的版本号,而CFBundleVersion则是对开发团队比较有意义的一个编号,可用于记录APP的开发记录,便于对APP的研发过程有一个较为系统的了解,比如版本号为1.0.1,build号最开始为1.0.1.0,新增某功能或优化后,build可改为为1.0.1.1,然后开发日志上记录,1.0.1.1,新增XXX,优化XXX.
以下是比较方法
//版本号判断
- (BOOL)localCompareWithAppStoreVerson:(NSString *)appVerson {
BOOL compareResult = NO;
//版本号获取
NSMutableString *localString = [NSMutableString new];
NSMutableString *appStoreString = [NSMutableString new];
if (self.length != appVerson.length) {
// 获取各个版本号对应版本信息
NSMutableArray *localArray = [NSMutableArray arrayWithArray:[self componentsSeparatedByString:@"."]];
NSMutableArray *appStoreArray = [NSMutableArray arrayWithArray:[appVerson componentsSeparatedByString:@"."]];
// 补全版本信息为相同位数
while (localArray.count < appStoreArray.count) {
[localArray addObject:@"0"];
}
while (appStoreArray.count < localArray.count) {
[appStoreArray addObject:@"0"];
}
//版本号重组
[localString appendString:[localArray firstObject]];
[appStoreString appendString:[appStoreArray firstObject]];
for (int i = 1; i < localArray.count; i++) {
[localString appendString:@"."];
[localString appendString:[localArray objectAtIndex:i]];
}
for (int i = 1; i < appStoreArray.count; i++) {
[appStoreString appendString:@"."];
[appStoreString appendString:[appStoreArray objectAtIndex:i]];
}
} else {
localString = [NSMutableString stringWithString:self];
appStoreString = [NSMutableString stringWithString:appVerson];
}
//对比版本号
NSComparisonResult compare = [appStoreString compare:localString options:NSNumericSearch];
if (compare == NSOrderedDescending) {
//应用商店应用版本号高于本地应用版本号
compareResult = YES;
}
return compareResult;
}
我是写了一个对字符串的扩展,所以可以直接使用字符串调用改方法,其中self指的是APP当前的版本号,appVerson指得是查询到的App Store里的版本号.
PS: App Store版本号查询,调用接口 "http://itunes.apple.com/cn/lookup?id=XXX",,,其中XXX为要查询的APPID,然后解析数据
NSArray *array = [responseObject objectForKey:@"results"];
NSDictionary *dic = [array firstObject];
NSString *appStoreVersion = [NSString stringWithFormat:@"%@",[dic objectForKey:@"version"]];
