Question

我正在调用一个方法我的另一个类，但我不能，我得到这个错误。我搜索它，但我找不到任何解决方法。请帮忙。

代码：

adres = [adres stringByAppendingString:[NSString stringWithFormat:@"%@", textArama.text]];

    BaseHttpPost *m_HttpDownloadSearch = [[[self class] alloc] init];
    [m_HttpDownloadSearch HttpPost:adres data:@""];

错误是：

请帮助我!!

Answer 1

您不应该使用[[[self class] alloc] init]。你可能想要[BaseHttpPost alloc] init]。

Answer 2

方法-(void)HttpPost:adres data:属于BaseHttpPost类..那么为什么要分配和初始化当前类的对象并从中调用此方法，Sarki_So_zleriViewController也许是调用此方法的viewcontroller而BaseHttpPost有方法

在调用另一个类的方法时抛出一个'NSException'错误实例后调用终止
