[英]xcode how to define the height and width of a view
HI everyone I'm french so scuse me for my english SO here is my question: How can we define the height and the width of view. 嗨,大家好,我是法国人,所以请为我的英语打扰,这是我的问题:我们如何定义视图的高度和宽度。 Here it name is flakeView. 在这里,它的名称是flakeView。 Here is the code : 这是代码:
UIImageView* flakeView = [[[UIImageView alloc] initWithImage:flakeImage] autorelease];
// use the random() function to randomize up our flake attributes
int startY = round(random() % 320);
// set the flake start position
flakeView.center = CGPointMake(490, startY);
flakeView.alpha = 1;
// put the flake in our main view
[self.view addSubview:flakeView];
[UIView animateWithDuration:7
animations:^{
// set the postion where flake will move to
flakeView.center = viewToRotate.center;
}];
CGRect frame = CGRectMake(xPosition, yPosition, width, height);
flakeView.frame = frame;
Note that xPosition and yPosition are the top left corner, not the center. 请注意,xPosition和yPosition是左上角,而不是中心。
