ios開發之APP升級的實現

ios開發之APP升級的實現
直接上代碼：

/** *  檢測軟體是否需要升級 */-(void)checkVersion{    NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@http://itunes.apple.com/cn/lookup?id=%i,iFeverAPPID]];    ASIHTTPRequest *request = [[ASIHTTPRequest alloc]initWithURL:url];    [request setUseCookiePersistence:YES];    [request setDelegate: self];    [request setDidFailSelector:@selector(getVersionRequestFailed:)];    [request setDidFinishSelector:@selector(getVersionRequestSuccess:)];    [request startAsynchronous];//開始非同步請求}-(void)getVersionRequestFailed:(ASIHTTPRequest *)request1{    NSLog(@從AppStore擷取版本資訊失敗！！);}-(void)getVersionRequestSuccess:(ASIHTTPRequest *)request1{    NSString *newVersion;    NSData *responseData = [request1 responseData];    NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:responseData options:NSJSONReadingAllowFragments error:nil];    NSArray *resultArray = [dic objectForKey:@results];    for (id config in resultArray) {        newVersion = [config valueForKey:@version];    }    if (newVersion) {        NSLog(@通過AppStore擷取的版本號碼是：%@,newVersion);    }    //擷取本地版本號碼    NSString *localVersion = [[[NSBundle mainBundle]infoDictionary]objectForKey:@CFBundleVersion];    NSString *msg = [NSString stringWithFormat:@你當前的版本是V%@，發現新版本V%@，是否下載新版本？,localVersion,newVersion];    if ([newVersion floatValue] > [localVersion floatValue]) {        UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@升級提示! message:msg delegate:self cancelButtonTitle:@下次再說 otherButtonTitles:@現在升級, nil];        alert.tag = kVersionNeedUpdateAlertTag;        [alert show];    }}

-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{    if (alertView.tag == kVersionNeedUpdateAlertTag) {        //軟體需要更新提醒        if (buttonIndex == 1) {            NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@https://itunes.apple.com/cn/app/wan-zhuan-quan-cheng/id%i?mt=8,iFeverAPPID]];            [[UIApplication sharedApplication]openURL:url];            /*             // 開啟iTunes 方法二:此方法總是提示“無法串連到itunes”，不推薦使用             NSString *iTunesLink = @itms-apps://phobos.apple.com/WebObjects/MZStore.woa/wa/viewSoftwareUpdate?id=%i&mt=8;             NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@itms-apps://phobos.apple.com/WebObjects/MZStore.woa/wa/viewSoftwareUpdate?id=%i&mt=8,iFeverAPPID]];             [[UIApplication sharedApplication] openURL:url];             */        }    }}
