解决方法
如果您询问是否要查找应用程序通过应用商店更新的时间,我不知道这样的方法.
执行此操作的hackie方法是将当前应用程序版本保存到NSUserDefaults,然后检查NSUserDefaults应用程序版本是否等于当前应用程序版本.
例如：
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
NSString *currentAppVersion = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleVersion"];
if ([defaults objectForKey:@"savedAppVersionKey"] != nil) {
//key exists
NSString *savedAppVersion = [[NSUserDefaults standardUserDefaults] objectForKey:@"savedAppVersionKey"];
if ([currentAppVersion isEqualToString:savedAppVersion]) {
//still running the same app version
}
else {
//the app version changed from the last launch
}
}
else {
//first run,set the key & synchronize
[[NSUserDefaults standardUserDefaults] setObject:currentAppVersion forKey:@"savedAppVersionKey"];
[[NSUserDefaults standardUserDefaults] synchronize]
}
}
我没有测试过代码,但它应该可以工作.
谢谢,
