Has anyone had an issue besides me where /n didn't produce a new line in an output string? This is a starter program taken from "Programming in Objective C" Fourth Edition by Stephen Kochan. The code runs without error but prints /n instead of advancing a line which is contrary to the text. Is there an Xcode dialog setting I need to look at or something?
Thanks,
Michael
// First programming example
#import <'Foundation/Foundation.h>
int main(int argc, const char * argv[])
{
@autoreleasepool {
// insert code here...
NSLog(@"Testing..../n....1/n....2/n....3");
}
return 0;
}
Objective-C(以及许多其他编程语言...)中的换行符不是\\n
/n
。
Escaping characters is when you use a backslash, not a forward slash, a new line is: \\n
and a carriage return is \\r
/n
is just... well "/n"
