Obj C 中的編碼

Question

NSString *s = [NSString stringWithCString:"Long dash symbol \xe2\x80\x94" encoding:(NSUTF8StringEncoding) ];

NSString *t = [NSString stringWithUTF8String:"Long dash symbol \xe2\x80\x94" ];

這兩條線有什么區別嗎？

不，兩種方法都調用

- (instancetype)initWithBytes:(const void *)bytes 
                       length:(NSUInteger)len 
                     encoding:(NSStringEncoding)encoding;
