【深入淺出IOS開發】繪製圖片

繪製圖片分兩步走：

①要加載圖片

②通過圖片對象進行繪製

drawInRect 和 drawAtPoint

//繪製圖片
void drawImage(CGRect rect)
{
    //1.加載圖片
    UIImage *imageOne = [UIImage imageNamed:@"1"];
   // NSLog(@"%@",self);
    //2.繪製圖片到view
    [imageOne drawInRect:CGRectMake(0, 10, rect.size.width , rect.size.height)];
    //[imageOne drawInRect:CGRectMake(0, 0, 300, 600)];
    //UIImage *imageTwo = [UIImage imageNamed:@"nt07_a01_m"];
    
    //[imageTwo drawAtPoint:CGPointMake(0, 0)];
 
}
