没人发现xcode下cocos2d-x跑起来cpu太高吗

Answer 1

都要用到NSSearchPathForDirectoriesInDomains 这个函数找path

写入信息到iOS txt file：

NSArray *paths = NSSearchPathForDirectoriesInDomains

(NSDocumentDirectory, NSUserDomainMask, YES);

NSString *documentsDirectory = [paths objectAtIndex:0];

NSString *fileName = [NSString stringWithFormat:@"%@/textfile.txt",

documentsDirectory];

NSString *content = [[NSString alloc] initWithContentsOfFile:fileName

usedEncoding:nil

error:nil];

content=@"something";

[content writeToFile:fileName

atomically:NO

encoding:NSStringEncodingConversionAllowLossy

error:nil];

读取信息用同样的path：

NSArray *paths = NSSearchPathForDirectoriesInDomains

(NSDocumentDirectory, NSUserDomainMask, YES);
