如何确定iOS设备上是否安装了Dropbox？

问题描述

我的应用使用Dropbox允许用户备份其核心数据存储。有没有办法以编程方式确定Dropbox应用程序是否已安装，所以我可以提示用户设置备份？我不想让那些不使用Dropbox的用户感到烦恼，但我想尝试让尽可能多的用户使用备份。

My app uses Dropbox to allow users to make backups of their core data store. Is there a way to determine programmatically if the Dropbox app has been installed, so I can prompt users to set up the backup? I don't want to bug users who don't use Dropbox, but I want to try to get as many users to use backups as possible.

推荐答案

Dropbox定义了自己的URI方案， dbapi-1 ，因此您可以看到操作系统是否可以使用该方案打开URL，如下所示： / p>

Dropbox define their own URI scheme, dbapi-1, and as such you can see if the OS can open URLs using that scheme, as so:

if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"dbapi-1://"]]) {
    NSLog(@"Dropbox is installed.");
} else {
    NSLog(@"Dropbox is not installed.");
}
