ios - how to switch visibility GONE and VISIBLE swift -


i want switch between 2 switch gone , visible doing on android, not know in swift try code in gone label

// set width constraint 0   let widthconstraint = nslayoutconstraint(item:  self.labelshortdescription, attribute: nslayoutattribute.width, relatedby: nslayoutrelation.equal, toitem: nil, attribute: nslayoutattribute.notanattribute, multiplier: 1, constant: 0)   self.labelshortdescription.addconstraint(widthconstraint)  // set height constraint 0    let heightconstraint = nslayoutconstraint(item:  self.labelshortdescription, attribute: nslayoutattribute.height, relatedby: nslayoutrelation.equal, toitem: nil, attribute: nslayoutattribute.notanattribute, multiplier: 1, constant: 0)    self.labelshortdescription.addconstraint(heightconstraint)

invisible:

this view invisible, still takes space layout purposes.

to achieve in ios:

yourview.alpha = 0

gone:

this view invisible, , doesn't take space layout purposes.

to achieve in ios:

yourview.removefromsuperview()

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 <...
