作为一个新手,运行他人的程序build时往往会在
+ (id) layerWithColor:(ccColor4B)color
{
return [[[self alloc] initWithColor:color] autorelease]; // <- ERROR HERE
}
处出现以下报错:
Sending 'ccColor4B' (aka 'struct_ccColor4B') to parameter of incompatible type 'CIColor *'
google了一下,发现问题在这里:
+ (id) layerWithColor:(ccColor4B)color
{
return [[(CCLayerColor*)[self alloc] initWithColor:color] autorelease];
}
调试,换之,仍不能运行,仍报错:
Use of undeclared'CCLayerColor'
忽然想起来新版本的区别,于是改为:
+ (id) layerWithColor:(ccColor4B)color
{
return [[(CCColorLayer*)[self alloc] initWithColor:color] autorelease];
}
