将项目转换为ARC，并在“泄漏工具”中将此功能重复标记为泄漏。
我当时认为objc_release可能是一个解决方案，但xCode不喜欢它。
- (int)getNumber{
int result = 0;
unsigned char *myBytes = (unsigned char *)malloc(sizeof(char));
[stream getBytes:myBytes range:NSMakeRange(0, sizeof(char))];
char tag = myBytes[0];
if((int)tag >= 0 ){
result = (int)tag - 64;
}
else if ((int)tag == -64 ) {
[self removeChar];
result = [self getInt];
}
else
{
[self removeChar];
unsigned char *byteTwo = (unsigned char *)malloc(sizeof(char));
[stream getBytes:byteTwo range:NSMakeRange(0, sizeof(char))];
char twoTag = byteTwo[0];
result =
((((int)tag & 0x03f) << 8) |
(twoTag & 0x0ff)) ;
result -= 8192;
}
return result;
}
函数中调用的两个函数是
- (void)removeChar{
[stream replaceBytesInRange:NSMakeRange(0, 1) withBytes:NULL length:0];
}
和
- (int)getInt{
NSRange intRange = NSMakeRange(0,3);
char buffer[4];
[stream getBytes:buffer length:4];
[stream replaceBytesInRange:intRange withBytes:NULL length:0];
return (int) (
(((int)buffer[0] & 0xff) << 24) |
(((int)buffer[1] & 0xff) << 16) |
(((int)buffer[2] & 0xff) << 8) |
((int)buffer[3] & 0xff) );
}
