我在网上搜索这个,但最终自己做到了。只需复制到viewdidload即可在应用程序第三次打开后显示提醒

NSArray *path = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES);
 NSString *documents = [path objectAtIndex:0];
 NSString *counterPath = [documents stringByAppendingPathComponent:@"counter.txt"];
 NSString *number = [NSString stringWithContentsOfFile:counterPath encoding:NSUTF8StringEncoding error:nil];
 int numberint = [number intValue];
 int opens = numberint + 1;
 NSString *dataString = [NSString stringWithFormat:@"%d", opens];
 NSData *data = [dataString dataUsingEncoding:NSUTF8StringEncoding];
 [data writeToFile:counterPath atomically:YES];


 if (opens == 3 ) {

  UIAlertView *myAlert = [[UIAlertView alloc]
        initWithTitle:@"*****" message:@"Please Rate 5 Stars to Support MY APP"
        delegate:self 
        cancelButtonTitle:nil
        otherButtonTitles:@"OK",nil];
  [myAlert show];
 }

I Was searchin the web for this but finaly made it by myself. Just copy to viewdidload to show the reminder after the app opened the third time

NSArray *path = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES);
 NSString *documents = [path objectAtIndex:0];
 NSString *counterPath = [documents stringByAppendingPathComponent:@"counter.txt"];
 NSString *number = [NSString stringWithContentsOfFile:counterPath encoding:NSUTF8StringEncoding error:nil];
 int numberint = [number intValue];
 int opens = numberint + 1;
 NSString *dataString = [NSString stringWithFormat:@"%d", opens];
 NSData *data = [dataString dataUsingEncoding:NSUTF8StringEncoding];
 [data writeToFile:counterPath atomically:YES];


 if (opens == 3 ) {

  UIAlertView *myAlert = [[UIAlertView alloc]
        initWithTitle:@"*****" message:@"Please Rate 5 Stars to Support MY APP"
        delegate:self 
        cancelButtonTitle:nil
        otherButtonTitles:@"OK",nil];
  [myAlert show];
 }

您应该使用 NSDefaults 来存储计数器值,而不是使用文本文件,并在启动时读取它。它会大大简化代码。

instead of using text file, you should have used NSDefaults to store the counter value, and just read it on launch. It would have simplified the code a lot.

与其构建自己的解决方案,为什么不使用现成的库来执行此操作呢?

例如这个;-): https://github.com/nicklockwood/iRate

这可以让你配置何时根据应用程序启动次数、安装天数和一堆其他参数显示评级提示,并将用户直接带到 iTunes 上的评级页面。

Rather than build your own solution, why not use an off-the-shelf library to do this?

Like this one for example ;-): https://github.com/nicklockwood/iRate

This lets you configure when the rating prompt will be shown based on number of app launches, number of days installed and a bunch of other parameters, and it takes the user directly to the ratings page on iTunes.
