一.需求

公司之前一直在用企业证书开发和发布，App一直挂在官网上进行下载安装，但是由于越到开发后期版本越多，维护版本统一越困难。所以又申请了一个公司发布到AppStore的版本。所以又把以前老的的流程梳理整理一下。开发中我们可能会遇到这样的需求，当AppStore中有新版本迭代更新，在用户点开APP的时候弹框提醒客户去AppStore更新APP。这里有两点要做的事情：

  1.获取AppStore的版本和本地的版本做对比

  2.如果本地版本比较低的话 提示用户是否到AppStore下载更新。

  3.不能显示的在app中提示,否则上传会被拒,可以放在App启动的时候弹出提示框

二、实现

 1.通过网络请求获取AppStore中的版本和本地版本做对比:以QQ为例
返回Json:

            }
        }

}

显示App有新版本

- (void)showAppHaveNewVeresion{

UIAlertView *sheet = [[UIAlertView alloc] initWithTitle:CPLocalizedString(@"Have a new version!") message:self.releaseNotes delegate:self cancelButtonTitle:CPLocalizedString(@"Cancel") otherButtonTitles:CPLocalizedString(@"OK"), nil];

[sheet show];

}

点击提示信息

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex

{

if (1 == buttonIndex) {

[self openAppaleShop];

}else{

NSString *cancelDate = [[NSDate date] fs_stringWithFormat:@"yyyy-MM-dd"];

[CPUserDefaultsTool saveWithValue:cancelDate forKey:CPAppVersioncancelDate];

}

   [self.window endEditing:YES];

  }

打开AppStore

- (void)openAppaleShop{
NSString *appleID = @"APPID";// iOS7和iOS8的打开方式不一样
if (iOS7) {
NSString *str = [NSString stringWithFormat:@"itms-apps://itunes.apple.com/app/id%@",appleID];

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:str]];

} else {

NSString *str = [NSString stringWithFormat:@"itms-apps://ax.itunes.apple.com/WebObjects/MZStore.woa/wa/viewContentsUserReviews?type=Purple+Software&id=%@", appleID];

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:str]];
