【问题描述】:
当我写作时
@implementation GameViewController
-(IBAction)StartGame:(id)sender{
StartGame.hidden = YES;
BirdMovement = [NSTimer scheduledTimerWithTimeInterval:0.05
target:self selector:@selector(BirdMoving) userInfo:nil repeats:YES];
}
-(void)BirdMoving{
Bird.center = CGPointMake(Bird.center.x, Bird.center.y - BirdFlight);
BirdFlight = BirdFlight - 5;
if (BirdFlight < -15) {
BirdFlight = -15;
if (BirdFlight > 0) {
Bird.image = [UIImage imageNamed:@"3.png"];
}
if (BirdFlight < 0) {
Bird.image = [UIImage imageNamed:@"4.png"];
}
}
-(void)touchesBegan:(NSSet *)touches withEvent: (UIEvent *)event{
BirdFlight =30;
}
它说我使用了一个未声明的标识符touchesBegan:
请帮帮我:)

您需要将代码缩进四个空格才能在 stackoverflow 上正确格式化。
