在 Obj C 中编码

Question

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

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

这两行有什么区别吗？

不，两种方法都调用

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