SDWebImage在設備上不起作用

Question

嗨，大家好，我已經集成了SDWebImage以便從Facebook加載圖像。 一切在模擬器上都可以正常工作，但是當我嘗試在設備上運行時，它給出了錯誤消息：

B'dayReminderPlus[415:307] -[UIImageView setImageWithURL:placeholderImage:]: unrecognized selector sent to instance 0x4f7d310

2012-08-17 14:45:15.301 B'dayReminderPlus[415:307] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIImageView setImageWithURL:placeholderImage:]: unrecognized selector sent to instance 0x4f7d310'

*** Call stack at first throw:

terminate called after throwing an instance of ‘NSException’

崩潰即將發生： [cell.contactImageView setImageWithURL:[NSURL URLWithString:[[contactList objectAtIndex:indexPath.row] objectForKey:PICTURE_KEY]]placeholderImage:[UIImage imageNamed:@"placeholder.png"]];

我不清楚為什么在模擬器上運行APP時會發生此崩潰。 任何幫助，將不勝感激。 提前感謝。

我也在設備上運行時遇到了這個問題。 我忘記在“其他鏈接器標志”設置中添加“ -Objc”標志。

添加鏈接器標志

打開“構建設置”選項卡，在“鏈接”部分中，找到“其他鏈接器標志”設置並添加“ -ObjC”標志：
