1、获取App Store版本信息
// 1、填写自己App的ID
NSString * strurl = [[NSString alloc] initWithFormat:@"http://itunes.apple.com/lookup?id=1491881948"];//替换为自己App的ID
NSURLSession *session=[NSURLSession sharedSession];
NSURL *url = [NSURL URLWithString:strurl];
//2.创建可变的请求对象
NSMutableURLRequest *request=[NSMutableURLRequest requestWithURL:url];
NSURLSessionDataTask *dataTask = [session dataTaskWithRequest:request completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error){
//4.解析数据
NSDictionary *dict=[NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:nil];
NSArray * results = dict[@"results"];
NSDictionary * dic = results.firstObject;
NSString * lineVersion = dic[@"version"];//版本号
NSString * releaseNotes = dic[@"releaseNotes"];//更新说明
NSString * trackViewUrl = dic[@"trackViewUrl"];//链接
DSLog(@"App store版本号:%@",lineVersion);
DSLog(@"更新说明:%@",releaseNotes);
DSLog(@"App下载链接:%@",trackViewUrl);
// 5、获取本地版本
NSDictionary *infoDictionary = [[NSBundle mainBundle] infoDictionary];
// 本地app版本
NSString *app_Version = [infoDictionary objectForKey:@"CFBundleShortVersionString"];
// 6、比较版本信息
if ([lineVersion floatValue] > [app_Version floatValue]) {
// 7、回到主线程进行后续操作
dispatch_async(dispatch_get_main_queue(), ^{
[self setGengxinUI];
});
DSLog(@"^^%@",app_Version);
}else{
// 7、回到主线程进行后续操作
dispatch_async(dispatch_get_main_queue(), ^{
[SOSVC SOSToolTipShow:@"提示" message:@"已是最新版本" cancelTitle:@"确定" otherTitle:nil];
});
}
}];
//3.执行任务
[dataTask resume];
2、跳转App Store和应用内下载更新app两种方式
- 跳转App Store 下载
// id99637153*是app的唯一id，对应上文的trackViewUrl
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"https://itunes.apple.com/cn/app/%E4%B8%9C%E6%96%B9%E7%BE%8E%E9%A3%9F/id99637153*?mt=8"] options:@{} completionHandler:nil];
2.应用内更新下载
导入头文件： #import <StoreKit/StoreKit.h>
准守协议：<SKStoreProductViewControllerDelegate>
1.实现代理SKStoreProductViewControllerDelegate
SKStoreProductViewController *storeProductViewContorller = [[SKStoreProductViewController alloc] init];
storeProductViewContorller.delegate = self;
[storeProductViewContorller loadProductWithParameters: @{SKStoreProductParameterITunesItemIdentifier : @"996371534"} completionBlock:^(BOOL result, NSError *error) {
if(error){
NSLog(@"错误%@",error);
}else{
//应用界面
[self.window.rootViewController presentViewController:storeProductViewContorller animated:YES completion:nil];
}
}];
//实现取消协议
- (void)productViewControllerDidFinish:(SKStoreProductViewController *)viewController{
[self.window.rootViewController dismissViewControllerAnimated:YES completion:nil];
[self disMiss];
}
