因为android太火了,所以开始学ios开发(你懂的),买了本《Objective-c 2.0程序设计》打算照着书对着敲,结果第一个HelloWorld就报错
int main (int argc,const char * argv[])
{
NSAutoreleasePool * pool = [[NSAutoreleasePoolalloc] init];
NSLog(@"Hello World!");
[pool drain];
return 0;
}
NSAutoreleasePool' is unavailable: not available in automatic reference counting mode
这我就纠结了,对着书敲都出问题,这让我怎么学啊,结果google了下发现原来我用的是X-code 4.2,苹果引入了自动记算引用数的功能,所以老的项目中
NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];是报错的,必须把arc(auto-reference-command)关闭才行,方法如下:
