CorePlot - '@'标记之前的预期令牌 [英] CorePlot - Expected Token Before '@' token

问题描述

我正在努力将CorePlot纳入我的项目。我终于设法使我的头文件被识别，但是我在main.m中收到以下错误。

@令牌之前的预期表达式

  int main（int argc，char * argv []）
 {
 @autoreleasepool {
 return UIApplicationMain （argc，argv，nil，NSStringFromClass（[ProjectFiveAppDelegate class]））; 
} 
} 
  

解决方案

最近引入了@autoreleasepool语法，您可能需要安装Xcode 4.2。另一种可能性是，您的编译器设置为GCC，AFAIK不支持那些较新的Objective-C更改。

如果这是更新的Objective-C扩展的唯一地方被使用，您可以简单地将其更改为

  NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init]; 
 int retVal = UIApplicationMain（... 
 [pool release]; 
 return retVal; 
  

I am trying to incorporate CorePlot into my project. I finally manages to get my header files recognized but i keep getting the following error in my main.m.

"Expected expression before '@' token"

int main(int argc, char *argv[])
{ 
    @autoreleasepool { 
    return UIApplicationMain(argc, argv, nil, NSStringFromClass([ProjectFiveAppDelegate     class]));
    }
}

解决方案

The @autoreleasepool syntax was introduced fairly recently, you probably need to install Xcode 4.2. Another possibility is that your compiler is set to GCC which AFAIK doesn't support those newer Objective-C changes.

If this is the only place where newer Objective-C extensions are used, you can simply change it to

NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
int retVal = UIApplicationMain( ...
[pool release];
return retVal;
