DAtA to nsstring

NSString *str = @"AA21f0c1762a3abc299c013abe7dbcc50001DD"; NSData* bytes = [str dataUsingEncoding:NSUTF8StringEncoding]; Byte * myByte = (Byte *)[bytes bytes]; NSLog(@"myByte = %s",myByte);

使用 [NSString stringWithFormat:NSData] (这里的NSData指的是需要转换成NSString的NSData变量)即可。 如果po出的NSData是不可阅读的乱码,那一般都是有编码格式的,最常用的是NSUTF8StringEncoding,另外还有NSASCIIStringEncoding等,你可以...

char* ch = "我靠我靠我靠了再靠"; NSData* data = [NSData dataWithBytes:ch length:30]; NSString* str = [NSString stringWithUTF8String:[data bytes]]; NSString* str2 = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncodi...

1、NSData 转NSString NSString *result =[[ NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]; 2、字符串转Data NSString *str =@"jesfds"; NSData *data =[str dataUsingEncoding:NSUTF8StringEncoding];

自己写个汉字编码的表,编码 to 汉字 一一对应

转换: NSString *string = @“"; //1、字符串转换成NSData NSData *data = [string dataUsingEncoding:NSUTF8StringEncoding]; //2、NSData转换成字符串 NSString * inString = [[NSString alloc]initWithData:data encoding:NSUTF8StringEncodi...

出现这种问题的原因是在于解析json时,你拿到的对象可能已经不再是NSString类型,而是NSDictionary类型。所以你在对这个你以为是NSString类型的对象进行isEqualToString 的判断时,因对象不是NSString类型,所以无法响应isEqualToString消息。故...

+ (NSDictionary *)dictionaryWithJsonString:(NSString *)jsonString { if (jsonString == nil) { return nil; } NSData *jsonData = [jsonString ...

Apple官方的文档: Return ValueAn NSString object initialized by converting the bytes in data into Unicode characters using encoding. The returned object may be different from the original receiver. Returns nil if the initializat...

1、NSData 转NSString NSString *result =[[ NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]; 2、字符串转Data NSString *str =@"jesfds"; NSData *data =[str dataUsingEncoding:NSUTF8StringEncoding];
