设置整数时，为什么会发生EXC_BAD_ACCESS和SIGABRT? [英] Why did happen EXC_BAD_ACCESS and SIGABRT when set integer?

问题描述

我写了代码.

我想使用nsuserdefault保存整数.

但是此代码发生在EXC_BAD_ACCESS和SIGABRT.

I wrote code.

I want to save integer using nsuserdefault.

But this code happen EXC_BAD_ACCESS and SIGABRT.

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    ...
    [self desave:[newys integerValue] :[newms integerValue]];
    ...
}

...

- (void)desave:(NSInteger*)year :(NSInteger*)month//←EXC BAD ACCESS happened on this row.
{
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];

    [defaults setInteger:year forKey:@"year"];//←SIGABRT happened on this row.

    [defaults synchronize];
}

推荐答案

此问题是由用于NSInteger参数的不必要的指针引起的.

The problem is caused by the needless pointers being used for the NSInteger parameters.

更改:

- (void)desave:(NSInteger*)year :(NSInteger*)month

收件人:

- (void)desave:(NSInteger)year :(NSInteger)month

NSInteger不是类类型.

您还应该为您的方法命名更好一些.现在，名称为desave::.最好是:

You should also name your method a little better. Right now the name is desave::. It would be better if it was:

- (void)desaveYear:(NSInteger*)year month:(NSInteger*)month

现在的名字是desaveYear:month:.

现在您可以通过以下方式调用它:

And now you can call it with:

[self desaveYear:[newys integerValue] month:[newms integerValue]];
