我正在尝试回忆一下我在另一个区块(void)viewDidLoad
中(void)moveObject
加载的图片。但是,因为我正在处理两个不同的块,我显然无法回想起这个图像。有没有什么方法可以重新安排代码才能使其正常工作?
- (void)viewDidLoad {
CGRect myImageRect = CGRectMake(200.0f, 350.0f, 52.0f, 100.0f);
UIImageView *myImage = [[UIImageView alloc] initWithFrame:myImageRect];
[myImage setImage:[UIImage imageNamed:@"flake.png"]];
myImage.opaque = YES;
[self.view addSubview:myImage];
moveObjectTimer = [NSTimer scheduledTimerWithTimeInterval:0.001 target:self selector:@selector(moveObject) userInfo:nil repeats:YES];
}
-(void) moveObject {
myImage.center = CGPointMake(myImage.center.x, myImage.center.y +1);
}
答案 0 :(得分:0)
为myImage或属性创建一个实例变量,如果你也喜欢getter和setter。
这里只是一个实例变量:
的.m
@implementation MyClass {
UIImageView *_myImage;
}
- (void)viewDidLoad
{
CGRect myImageRect = CGRectMake(200.0f, 350.0f, 52.0f, 100.0f);
UIImageView *myImage = [[UIImageView alloc] initWithFrame:myImageRect];
[myImage setImage:[UIImage imageNamed:@"flake.png"]];
myImage.opaque = YES;
[self.view addSubview:myImage];
_myImage = myImage;
}
-(void) moveObject {
_myImage.center = CGPointMake(_myImage.center.x, _myImage.center.y +1);
