實現文件中的錯誤

在我的實現文件中出現了一些讓我無法編譯的錯誤，但是我無法弄清楚它們。在此先感謝您的幫助。實現文件中的錯誤

是您的問題1實際上應該是這樣的：我如何修復'@end'在實現上下文中缺少？ – sarnold 2012-02-21 01:53:49

是的，我無法弄清楚如何解決這個問題。 – pdenlinger 2012-02-21 06:17:38

以下是你在你的源文件註釋中的錯誤。

第一：

@implementation TNRViewController //'@end' is missing in implementation context

這意味着你在.m文件的末尾缺少@end。

二：

[myBackground.image = [bgImages objectAtIndex:currentBackground]; //Expected identifier

應該是：

myBackground.image = [bgImages objectAtIndex:currentBackground];

三：

if (CGRectContainsPoint([myIcon frame], [touch locationInView:nil])); // if statement has empty body

應該

if (CGRectContainsPoint([myIcon frame], [touch locationInView:nil])) // Remove the semi column
