iOS之@selector的函数传递多个参数

1、一般情况，使用 self performSelector:SEL withObject:id方法

[self performSelectorOnMainThread:@selector(testAA:) withObject:[NSArray arrayWithObjects:@1,@2, nil] waitUntilDone:NO];


-(void) testAA:(NSArray*)data{
 
    if (data==nil||data.count!=2) {
        return;
    }
    NSInteger num=[(NSString*)data[0] intValue];
    NSInteger index=[data[1] intValue];
}

NSMutableDictionary *dict = [[NSMutableDictionary alloc] init];  
[dict setObject:oldView forKey:@oldView];
[NSTimer scheduledTimerWithTimeInterval:0.0 target:self selector:@selector(onTimer:) userInfo:dict repeats:NO];  
[dict release];

- (void)onTimer:(NSTimer *)timer {  
    UIView *oldView = [[timer userInfo] objectForKey:@oldView];
}

UIButton * markButton=[[UIButton alloc] initWithFrame:CGRectMake(280, 0, 30, 30)];
markButton.tag=@参数值; //这里是你要传递的参数值
[markButton addTarget:self action:@selector(addMark:)  forControlEvents:UIControlEventTouchUpInside];

-(BOOL) addMark:(UIButton *)btn {
    NSLog(@%@,btn.tag];
｝
