NSAutoReleaseNoPool() 错误,加上一个奇怪的错误

发布于 2024-10-01 15:32:52 字数 1969 浏览 5 评论 0原文

我有以下代码,但遇到了一些问题。任何帮助将不胜感激。当我运行代码时,出现错误:

2010-11-11 12:28:15.352 addressBook[25563:a0f] *** __NSAutoreleaseNoPool(): NSCFArray 类的对象 0x100111010 自动释放,没有池 - 只是泄漏

我尝试添加一个自动释放池,但它给了我更严重的错误(完全停止了程序运行),但也许我做错了?

另外,由于某种原因,在它提示输入姓名后,它会在我有机会输入任何内容之前立即提示输入地址..但它只在我添加的第一个联系人上执行此操作。我不知道这是怎么发生的......

how many address would you like to input?

Please input the name of contact
Please input the address of contact

Please input the birthday of contact

等等,等等。

printf("how many address would you like to input?\n");
int numAddresses;
scanf("%i", &numAddresses);
if(numAddresses<1) return 0;
NSMutableArray * arrayOfBooks = [NSMutableArray array];
for (int i = 0; i < numAddresses; ++i) {
    book * f = [[book alloc] init];
    [arrayOfBooks addObject:f];
    [f release];

}
unsigned count = [arrayOfBooks count];
while (count--) {
    id object = [arrayOfBooks objectAtIndex:count];

    printf("Please input the name of contact\n");
    char inputString1[50];
    if(fgets(inputString1, sizeof inputString1, stdin)){
        [object setName: inputString1];
    }

    printf("Please input the address of contact\n");
    char inputString2[50];
    fgets(inputString2, sizeof inputString2, stdin);
    [object setAddress: inputString2];

    printf("Please input the birthday of contact \n");
    char inputString3[50];
    fgets(inputString3, sizeof inputString3, stdin);
    [object setBirthday: inputString3];

    printf("Please input the phone number of contact \n");
    char inputString4[50];
    fgets(inputString4, sizeof inputString4, stdin);
    [object setPhoneNumber: inputString4];

    [object print]; 

}

return 0;

提前致谢。

I have the following code, and am having some problems with it. Any help would be appreciated. When I run the code, I got an error:

2010-11-11 12:28:15.352 addressBook[25563:a0f] *** __NSAutoreleaseNoPool(): Object 0x100111010 of class NSCFArray autoreleased with no pool in place - just leaking

I tried adding an autorelease pool, but it gave me much worse errors (that stopped the program running at all), but maybe I did it wrong?

Also, for some reason, after it prompts for a name input, it instantly prompts for the address input before I have a chance to enter anything.. but it only does this on the first contact I'm adding. I have no idea how this could happen..

how many address would you like to input?

Thanks in advance.

如果您使用 Objective-C,则必须使用自动释放池包装整个 main 函数。你像这样使用它:

int main(int argc, char** argv) {
   NSAutoreleasePool* pool = [[NSAutoreleasePool alloc] init];

   // real code here

   [pool drain];
   return 0;
}

If you are using Objective-C, you must wrap the whole main function with an auto release pool. You use it like this:

int main(int argc, char** argv) {
   NSAutoreleasePool* pool = [[NSAutoreleasePool alloc] init];

   // real code here

   [pool drain];
   return 0;
}
