iphone - 警告:传递'setOn:'的参数1将使指针产生整数而不进行强制转换

我是Objective C的新手，如果这是一个愚蠢的问题，我表示歉意。我在以下代码中收到此错误。

我正在使用recurringBool作为全局变量

//Declared in the AppDelegate.h
extern BOOL *recurringBool;

//Defined in the AppDelegate.m
BOOL *recurringBool;

// In another class this method sets recurringBool
- (IBAction)MakeRecurring:(id)sender {
    UISwitch *Switch = (UISwitch *)sender;
    //this is where the 1st error is occurring. aNetS is a UISwitch
    recurringBool = Switch.on;
        **//warning: assignment makes pointer from integer without a cast**
}

//And in another method aNetS is set to recurringBool;
//this is where the second error is occurring. aNetS is a UISwitch
aNetS.on = recurringBool;
    //warning: passing argument 1 of 'setOn:' makes integer from pointer without a cast

我不确定为什么会出现这些错误，因为recurringBool不是整数。所以我必须假设我使用错了。任何帮助将不胜感激。

最佳答案

从BOOL声明中删除*。 BOOL不是指针。
