Make C char array from NSString object in Obj-C

Question

I want to make a C char array from NSString object in Obj-C.

My string is:

NSString *string = [[NSString alloc] initWithContentsOfURL:url usedEncoding:nil error:nil];

Can someone send me a sample of a working code?

Thanks in advance,

Answer 1

您可以使用UTF8String方法：

const char *str = [string UTF8String];

Answer 2

NSData *data = [string dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];

void *bytes = [data bytes];

(Credit: NSString - Unicode to ASCII equivalent )

Or as one line:

void *bytes = [[string dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES] bytes];
