新上传的App可能没法通过http://itunes.apple.com/lookup?id来获取到信息,这样的话就需要后台的接口来支持了
直接获取AppStore上面的App信息，省去了后台单独写接口支持
话不多说,直接上代码
/**
判断AppStore是否有新版本
@param appId appId
@param completion block回调
*/
+ (void)isUpdatedInAppStoreWithAppId:(NSString *)appId Completion:(void (^)(BOOL isUpdate, NSString *newVersion, NSString *updateLog))completion;
+ (void)isUpdatedInAppStoreWithAppId:(NSString *)appId Completion:(void (^)(BOOL, NSString *, NSString *))completion{
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"http://itunes.apple.com/lookup?id=%@",appId]];
NSString *appInfo = [NSString stringWithContentsOfURL:url encoding:NSUTF8StringEncoding error:nil];
NSData *data = [appInfo dataUsingEncoding:NSUTF8StringEncoding];
NSError *error;
NSDictionary *dict = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:&error];
if (error) {
NSLog(@"解析失败:%@",error);
}
NSDictionary *infoDict = dict[@"results"][0];
NSString *updateLog = infoDict[@"releaseNotes"];
NSString *newVersion = infoDict[@"version"];
NSString *oldVersion = [NSBundle mainBundle].infoDictionary[@"CFBundleShortVersionString"];
BOOL isUpdate = NO;
if ([oldVersion compare:newVersion options:NSNumericSearch] == NSOrderedAscending) {
isUpdate = YES;
}
completion(isUpdate,newVersion,updateLog);
}
