iphone - 如何将 3 个参数传递给@selector

Question

我在

中创建了一个 Action

-(void) ccTouchEnded:(UITouch *)touch withEvent:(UIEvent *)event

就像这样:

self.moveAction = [CCSequence actions:                          
                   [CCMoveTo actionWithDuration:moveDuration position:touchLocation],
                   [CCCallFunc actionWithTarget:self selector:@selector(guyMoveEnded)],
                   nil
                  ];

但是现在，我想通过@selector 自动调用以下方法:

-(void)guyMoveEnded:(BOOL)flag AndWhere:(CGPoint)where Andtime:(float)time{
    //do something...
}

我该怎么做？请帮助我，我对选择器感到困惑。

谢谢!

您可以将您的参数添加到 NSArray 中，然后将其作为参数提供给您的选择器:

NSArray *params = [NSArray arrayWithObjects:@"a str", [NSNumber numberWithInt:42],myObj];
[self performSelector:@selector(myMethod:)withObject:params];

然后在你的方法中解压参数:

-(void)myMethode:(NSArray*)params
{
    NSString *strArg = [params objectAtIndex:0];
    NSNumber * numVal = [params objectAtIndex:1];
    NSObject *objArg = [params objectAtIndex:2];
    int intArg = [numVal intValue];
    .
    .
    .   
}
