关于creator2.0 setRect接口失效

Creator 2.x
#1

let sprite = this.node.addComponent(cc.Sprite);
sprite.spriteFrame = new cc.SpriteFrame(texture);
let rect = sprite.spriteFrame.getRect();
let newRectWidth = rect.width / colNum;
let newRectHeight = rect.height / colNum;

    let newRectX = col * newRectWidth;
    let newRectY = (colNum - row - 1) * newRectHeight;


    let newRect = cc.rect(0, 0, 10, 10);
    sprite.spriteFrame.setRect(newRect);
    console.log(newRect)
#2

打印rect是 0 0 10 10
但是显示还是整张图片

#3

sprite的sizemode属性

#4

2.0需要显示指定了么，1.93上面的代码是可以的

#5 
    let newRect = cc.rect(0, 0, 10, 10);
    sprite.spriteFrame.setRect(newRect);
    sprite.sizeMode = cc.Sprite.SizeMode.CUSTOM;
    console.log(newRect)

还是不行，几个值都试了

#6

如果是新创建的SpriteFrame
var spriteFrame = new cc.SpriteFrame
spriteFrame.setTexture(this.testTexture, cc.rect(100, 100, 200, 200))
sprite.spriteFrame = spriteFrame

如果是已有的spriteFrame 只是设置区域不需要设置纹理
spriteFrame.setTexture(this.testTexture)
spriteFrame.setRect(cc.rect(100, 100, 200, 200))
spriteFrame._calculateUV() // 无奈，这里只能调用这个私有方法
sprite.spriteFrame = spriteFrame

#7

1.10.2在浏览器上能显示，在模拟器报错，安卓包也报错
