该方法在调用时不会运行某些行

Question

// setup.m

void receiveData(CFSocketRef s, CFSocketCallBackType type, 
             CFDataRef address, const void *data, void *info)
{ 

gameboard *board = [[gameboard alloc] initWithNibName:nil bundle:nil];


NSString *buffer = [[NSString alloc] initWithData:(NSData *)data
encoding:NSUTF8StringEncoding];

NSLog(@"Buffer is %@", buffer);

[board activateButton:buffer]; 

// gameboard.m

-(void) activateButton:(NSString *)trigger;{

[self viewDidLoad];

NSLog(@"Received from setup: %@", trigger);
upDatePos = [trigger intValue];
NSLog(@"upDatePos is %d",upDatePos);
btnMyButton.enabled = YES;
[self drawPosition:upDatePos];
NSLog(@"End of activateButton");
}


-(void) p2drawPosition:(int)number;{

NSLog(@"Number in p2draw Position is %d",number);
xPos = [[P2XArraypos objectAtIndex:number]intValue];
yPos = [[P2YArraypos objectAtIndex:number]intValue];
NSLog(@"xPos is %f",xPos);
NSLog(@"yPos is %f",yPos);

image2.center= CGPointMake(xPos,yPos);

}

当我运行它时。我的视图将被设置 - ＆gt; gameboard.tcp服务器将创建和runloop接收传入的数据然后.y视图将停止在游戏板上并等待设置中的数据（缓冲区）调用activateButton。在activateButton调用之后，它也应该运行这些行

btnMyButton.enabled = YES;
image2.center= CGPointMake(xPos,yPos);

但我的按钮仍然禁用，而我的image2仍未更新位置 我也用UIAlertView进行测试，它在调用时仍会弹出。

有谁能告诉我发生了什么事？以及如何解决它

非常感谢。
