1.获取当前项目APP版本号
2.拿到AppStore项目版本号
3.对比版本号,实现更新功能
直接上代码:
#import "ViewController.h" //1一定要先配置自己项目在商店的APPID,配置完最好在真机上运行才能看到完全效果哦 #define STOREAPPID @"1080182980" @interface ViewController () @end @implementation ViewController - (void)viewDidLoad { [super viewDidLoad]; //一句代码实现检测更新 [self hsUpdateApp]; } /** * 天朝专用检测app更新 */ -(void)hsUpdateApp { //2先获取当前工程项目版本号 NSDictionary *infoDic=[[NSBundle mainBundle] infoDictionary]; NSString *currentVersion=infoDic[@"CFBundleShortVersionString"]; //3从网络获取appStore版本号 NSError *error; NSData *response = [NSURLConnection sendSynchronousRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"http://itunes.apple.com/cn/lookup?id=%@",STOREAPPID]]] returningResponse:nil error:nil]; if (response == nil) { NSLog(@"你没有连接网络哦"); return; } NSDictionary *appInfoDic = [NSJSONSerialization JSONObjectWithData:response options:NSJSONReadingMutableLeaves error:&error]; if (error) { NSLog(@"hsUpdateAppError:%@",error); return; } NSArray *array = appInfoDic[@"results"]; NSDictionary *dic = array[0]; NSString *appStoreVersion = dic[@"version"]; //打印版本号 NSLog(@"当前版本号:%@\n商店版本号:%@",currentVersion,appStoreVersion); //4当前版本号小于商店版本号,就更新 if([currentVersion floatValue] < [appStoreVersion floatValue]) { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"版本有更新" message:[NSString stringWithFormat:@"检测到新版本(%@),是否更新?",appStoreVersion] delegate:self cancelButtonTitle:@"取消"otherButtonTitles:@"更新",nil]; [alert show]; }else{ NSLog(@"版本号好像比商店大噢!检测到不需要更新"); } } - (void)alertView:(UIAlertView*)alertView clickedButtonAtIndex:(NSInteger)buttonIndex { //5实现跳转到应用商店进行更新 if(buttonIndex==1) { //6此处加入应用在app store的地址,方便用户去更新,一种实现方式如下: NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"https://itunes.apple.com/us/app/id%@?ls=1&mt=8", STOREAPPID]]; [[UIApplication sharedApplication] openURL:url]; } } @end
