NSData转NSString
这种方法效率低下
NSData *data = UIImagePNGRepresentation(image);
NSMutableString *picStr = [NSMutableString stringWithString:@"["];
Byte *dataByte = (Byte *)[data bytes];
int length = [data length];
//字节流转nsstring;
for(int i = 0;i < length;i++){
[picStr appendFormat:@"%d,",(int8_t)dataByte[i]];
}
