ios - Load an image in UIImageView and resize the container - swift -


i have s3 link using need load image in uiimageview. don't have dimensions of image me. have defined mainimageview (leading , trailing constraints) in storyboard

in code, loading image using:

mainimageview.setimagewith(url(string: ("https:" + (content?.imagepath)!)), placeholderimage: nil)

do have way of resizing container once image loads? want container take dimensions (height , width) of image. heard there called content wrap in android achieve same. however, unable find equivalent in ios.

if using autolayout, dont have uiimageview has intrinsic size makes take width , height of image. in .xib or .storyboard need position image view can resolve position(horizontal , vertical). size can provide default image(ow autolayout show error).

when change image @ runtime, imageview take size of image.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
