objective-c - oc获取DocumentDirectory目录报错expected identifier

Question

获取DocumentDirectory目录报错为什么会报错expected identifier

Answer 1

Because your grammar is wrong.

NSArray *docs = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES);

or

NSString ＊path ＝ [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES) objectAtIndex:0];

Answer 2

NSSearchPathForDirectoriesInDomains is a C function, not a method of a certain OC class, so the outermost square brackets are not needed.
