調整字符串以顯示單數或複數單詞

Question

我正在顯示圖像具有的喜歡數量。我想避免典型的「1喜歡」，沒有成功。這是我現在的代碼。問題是應用程序崩潰，如果我使用此代碼，但它看起來很好。數據源是隻包含數字的NSMutableArray。

if ([[mainDelegate.imagesLikes objectAtIndex:indexPath.section] isEqualToString:@"1"]) { 
    likesLabel.text = [NSString stringWithFormat:@"%@ %@", [mainDelegate.imagesLikes objectAtIndex:indexPath.section], @"Like"]; 
} else { 
    likesLabel.text = [NSString stringWithFormat:@"%@ %@", [mainDelegate.imagesLikes objectAtIndex:indexPath.section], @"Likes"]; 
} 

崩潰日誌：

-[__NSCFNumber isEqualToString:]: unrecognized selector sent to instance 0xb000000000000023

Answer 1

這是發生，因爲你所得到的值不是一個的NSString，但__NSCFNumber。嘗試只是做這樣的事情：

if ([[mainDelegate.imagesLikes objectAtIndex:indexPath.section] integerValue] == 1) { 
    likesLabel.text = [NSString stringWithFormat:@"%@ %@", [mainDelegate.imagesLikes objectAtIndex:indexPath.section], @"Like"]; 
} else { 
    likesLabel.text = [NSString stringWithFormat:@"%@ %@", [mainDelegate.imagesLikes objectAtIndex:indexPath.section], @"Likes"]; 
}
