我有一个非常有线的问题,我不知道如何解决它。我正在设置UIButtons框架的动画,当我为它设置动画时,我希望按钮中的图像缩放到与按钮相同的大小。它可以在我的iPhone模拟器上无需任何操作。但是当我在iPad模拟器上运行它时,它不会改变图像大小。我在几个地方添加了[[gissaImg1 imageView] setContentMode:UIViewContentModeScaleToFill]代码,但它没有帮助。
有谁知道出了什么问题以及如何解决这个问题?
//Code to set the image
UIImage *image = [UIImage imageNamed:[NSString stringWithFormat:@"%@_small",
[[itemsForRound objectAtIndex:[[guessItems objectAtIndex:0] intValue]] valueForKey:@"Name"]]];
[self.gissaImg1 setImage:image forState:UIControlStateNormal];
[self.gissaImg1 setImage:image forState:UIControlStateHighlighted];
//Code to animate button
CGRect animateToSpot = (isIphone) ? CGRectMake(0, 0, 480, 320) : CGRectMake(0, 0, 1024, 768);
[self performSelector:@selector(PlayCorrectSound:) withObject:nil afterDelay:1];
[[gissaImg1 imageView] setContentMode:UIViewContentModeScaleToFill];
[UIView animateWithDuration:1.5 delay:0 options:(UIViewAnimationOptionAllowUserInteraction | UIViewAnimationCurveLinear) animations:^{
switch (index) {
case 0:
[[gissaImg1 imageView] setContentMode:UIViewContentModeScaleToFill];
[self.gissaImg1 setFrame:animateToSpot];
[self.view bringSubviewToFront:gissaImg1];
break;
.......

尝试使用setBackgroundImage
代替setImage
,并对图片不执行任何操作。 (resize或setContentMode)
希望这有帮助

UIImage *thubNailImage=[UIImage imageNamed:@"thumImage"];
[button.imageView setContentMode:UIViewContentModeScaleAspectFill];
CGSize imageSize=thubNailImage.size;
[button setImage:thubNailImage forState:UIControlStateNormal];
button.titleEdgeInsets = UIEdgeInsetsMake(0, -imageSize.width, 0, 0);
如果您不想显示标题,请删除最后一行(button.titleEdgeInsets = UIEdgeInsetsMake(0, -imageSize.width, 0, 0);
)
我认为这对某人有帮助。 :)
