Question

大家好我已经整合了SDWebImage来加载来自Facebook的图像。所有的东西在模拟器上工作正常但是当我尝试在设备上运行它会给出错误：

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’

此次崩溃即将发生：[cell.contactImageView setImageWithURL:[NSURL URLWithString:[[contactList objectAtIndex:indexPath.row] objectForKey:PICTURE_KEY]]placeholderImage:[UIImage imageNamed:@"placeholder.png"]];

我不清楚为什么在模拟器上运行APP时会发生这种崩溃。任何帮助，将不胜感激。提前完成。

添加链接器标记

打开“构建设置”选项卡，在“链接”部分中找到   “其他链接器标志”设置并添加“-ObjC”标志：
