Objective C General Print
提问by Casebash
Does objective C have a general print command like Python? NSLog seems to log it rather than print out to console. printf only accepts specific types.
目标 C 是否有像 Python 这样的通用打印命令？NSLog 似乎记录它而不是打印到控制台。printf 只接受特定类型。
回答by phoebus
NSLog()does print to the console, and is very similar to C's printf(). Having its origins and basis in C, console printing is done as it is in C, essentially.
NSLog()确实打印到控制台，并且非常类似于 C 的printf(). 控制台打印的起源和基础是在 C 中完成的，本质上是在 C 中完成的。

printfis what you're looking for. You can use it like a regular print statement:
printf就是你要找的。您可以像使用常规打印语句一样使用它：
printf("This is a neat command!\n");
You're also probably aware that you can use it with substitutions:
您可能还知道可以将其与替换一起使用：
printf("The Answer is %d\n", 42);

You can use NSStringto format strings containing id types as well as the standard printf types, then just print it using printf:
您可以使用NSString格式化包含 id 类型以及标准 printf 类型的字符串，然后使用 printf 打印它：
NSString *fmt = [NSString stringWithFormat:@"My formatted string: %@", anObject];
printf("%s", [fmt cStringUsingEncoding:[NSString defaultCStringEncoding]]);
