How do I use cgsize make?
提问by jwhyyou
I have been trying to use cgsizemakeas follows:
我一直在尝试使用cgsizemake如下：
I'm trying to make the frame of my image a different size using cgrectmakeinstead of changing the coordinates.
我正在尝试使用cgrectmake而不是更改坐标使我的图像的框架具有不同的大小。
So far I have tried
到目前为止我已经尝试过
maincharacter.frame = cgsizemake (14, 14);
but I keep getting the error
但我不断收到错误
assigning to cgrect from incompatible type CGsize
从不兼容的类型 CGsize 分配给 cgrect

One solution would be:
一种解决方案是：
CGRect frame = maincharacter.frame;
frame.size = CGSizeMake(14, 14);
maincharacter.frame = frame;

CGSize only accepts height and width
CGSize 只接受高度和宽度
CGSize c=CGSizeMake(width, height);
If you want to set the frame size use CGRectMake
如果要设置框架大小，请使用 CGRectMake
maincharacter.frame=CGRectMake(x-origin,y-origin, width, height);

maincharacter.frame must return (x, y, width, height) 4 parameters and CGSizeMake only have "width" and "height" 2 parameters. So You got an error. The solution is use frame.size, which returns 2 parameters to work with CGSizeMake(14, 14).
maincharacter.frame 必须返回(x, y, width, height) 4个参数，CGSizeMake只有“width”和“height”2个参数。所以你有一个错误。解决方案是使用 frame.size，它返回 2 个参数来处理 CGSizeMake(14, 14)。

CGSize viewwidth;
viewwidth=[[UIScreen mainScreen] bounds].size;
this will help you to get device current resolution using cgsize.
这将帮助您使用 cgsize 获取设备当前分辨率。
viewwidth.width or viewwidth.height
as above u can use it. and also as below code
如上所述，您可以使用它。以及如下代码
rightslide=[[UIView alloc]initWithFrame:CGRectMake(0,0, viewwidth.width, viewwidth.height)];

below is an example of using CGSizeMake in a UIScrollView
下面是在 UIScrollView 中使用 CGSizeMake 的示例
var mainScrollView: UIScrollView?
var numPages = 3
override func viewDidLoad() {
super.viewDidLoad()
//this gets the screen frames size
var fm: CGRect = UIScreen.mainScreen().bounds
//creates a UIScrollView programmatically
self.mainScrollView = UIScrollView(frame:CGRectMake(0, 0, fm.size.width, fm.size.height))
self.mainScrollView!.contentSize = CGSizeMake(self.mainScrollView!.frame.size.width, self.mainScrollView!.frame.size.height * CGFloat(numPages))
}

To use the variable cwhich is of type CGSizeyou would call c.0and c.1for the height and width respectively. I don't know why they named those properties 0 and 1 but you will have to take that up with Dennis Ritchie
要使用c类型的变量，CGSize您将分别调用c.0和c.1用于高度和宽度。我不知道他们为什么将这些属性命名为 0 和 1，但您必须与丹尼斯·里奇（Dennis Ritchie）一起接受
Here is an example usage of CGSizeMake:
这是一个示例用法CGSizeMake：
var makeSize = CGSizeMake(size.0, size.1)
let circ = SKShapeNode(ellipseOfSize: makeSize)
Hope that helps.
希望有帮助。
