ContentMode scaleAspectToFit不起作用
|
我有3个意见。
1.它是主视图，并且包含其他两个视图。
2.这个观点比第一个观点要大。
3.它包含在第二个视图中。
我想将第二个（显然是第三个）的大小调整为第一个视图的大小，以保持宽高比。我尝试将contentMode设置为scaleToAspectFitt来获得此结果，但是它不起作用。
UIView *yellowView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 200, 200)];
yellowView.autoresizesSubviews = YES;
yellowView.backgroundColor = [UIColor yellowColor];
yellowView.autoresizesSubviews = YES;
yellowView.contentMode = UIViewContentModeScaleAspectFit;
UIView *blueView = [[UIView alloc] initWithFrame:CGRectMake(0,0,350,400)];
blueView.autoresizesSubviews = YES;
blueView.contentMode = UIViewContentModeScaleAspectFit;
blueView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
UIView *darkView = [[UIView alloc] initWithFrame:CGRectMake(200, 100, 40, 40)];
darkView.backgroundColor = [UIColor blackColor];
darkView.contentMode = UIViewContentModeScaleAspectFit;
darkView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
[blueView addSubview:darkView];
[yellowView addSubview:blueView];
[self.view addSubview:yellowView];
[yellowView setNeedsLayout];
[darkView release];
[blueView release];
[yellowView release];
