我想我的動畫所以UIImageView
它從高度動畫x到高度y和我有以下代碼:動畫一個UIImageView
- (void)viewDidLoad
{
[super viewDidLoad];
self.test = [self createNewBarWithValue:800 atLocation:CGPointMake(107, 43)];
}
- (UIImageView*)createNewBarWithValue:(float)percent atLocation:(CGPoint)location
{
UIImageView *newBar = [[[UIImageView alloc] initWithFrame:CGRectMake(location.x, location.y, 107, 43)] autorelease];
newBar.image = [UIImage imageNamed:@"bar.png"];
CABasicAnimation *scaleToValue = [CABasicAnimation animationWithKeyPath:@"transform.scale.y"];
scaleToValue.toValue = [NSNumber numberWithFloat:percent];
scaleToValue.fromValue = [NSNumber numberWithFloat:0];
scaleToValue.duration = 1.0f;
scaleToValue.delegate = self;
newBar.layer.anchorPoint = CGPointMake(0.5, 1);
[newBar.layer addAnimation:scaleToValue forKey:@"scaleUp"];
CGAffineTransform scaleTo = CGAffineTransformMakeScale(1.0f, percent);
newBar.transform = scaleTo;
return newBar;
}
不過,我不是在這裏看到任何東西。我錯過了什麼?
它在IB創建,我已經連接的插座以及 – adit
但你似乎重新分配出口(self.test),這將失去你曾與IB創建的UIImageView原來的連接。如果要縮放在IB中創建的圖像視圖,請將變換應用於self.test; theres不需要創建一個新的UIImageView。 – Sam
