Question

我想在UIActivityViewController中添加一个整数，但它不起作用。这是我的代码：

- (IBAction)socialButton:(id)sender {
    NSString *shareText = @"I just scored %i in Helicave!", scoreNumber;
    NSArray *itemsToShare = @[shareText];
    UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:itemsToShare applicationActivities:nil];
    activityVC.excludedActivityTypes = @[UIActivityTypePostToFlickr, UIActivityTypePostToTencentWeibo, UIActivityTypePostToWeibo, UIActivityTypePostToVimeo];
    [self presentViewController:activityVC animated:YES completion:nil];
}

Answer 1

这一行：

NSString *shareText = @"I just scored %i in Helicave!", scoreNumber;

需要：

NSString *shareText = [NSString stringWithFormat:@"I just scored %i in Helicave!", scoreNumber];

Answer 2

尝试更改第一行

NSString *shareText = @"I just scored %i in Helicave!", scoreNumber;

为：

NSString *shareText = [NSString stringWithFormat:@"I just scored %i in Helicave!", scoreNumber];

在创建字符串

之前，您需要告诉XCode该字符串将具有格式，如%@或%i
