在两个方法之间传递变量

Question

I was trying to pass a variable of type NSString from a method to another. what I have done is:

-(void)some{
NSString *lat = something
NSString *longt = somethingElse
[self test:lat:longt];
}

and then

- (IBAction)test:(NSString *)lat:(NSString *)longt{
doSomeThing
}

But my problem is that now the IBAction button is activated without my press.

how do I run the method IBAction under my control

Answer 1

you cannot pass arbitrary parameters through an IBAction, you can either pass the control sending the action or nothing:

-(IBAction)action:(id)sender;
or
-(IBAction)action;

Answer 2

The test method should not be an IBAction . Instead do this:

- (void)test:(NSString *)lat:(NSString *)longt{
    //doSomeThing
}

-(IBAction)myAction:(id)sender
{
    //call test from here
    [self some];
}

Answer 3

You should use void as returm type of method not ibaction. If u need it for some action thn call it from there.

Answer 4

use

- (void) test:(NSString *)lat:(NSString *)longt

instead of

- (IBAction)test:(NSString *)lat:(NSString *)longt
