iOS Swift - Debugging Memory Leaks -


i'm working on app , has horrible memory leaks. observed far more use app, more memory consumes. thought way navigation handled. have slide menu framework written in objective c. in swift file (header handled) added following code:

if let app = uiapplication.shared.delegate as? appdelegate, let window = app.window {        if let viewcontrollers = window.rootviewcontroller?.childviewcontrollers {                 viewcontroller in viewcontrollers {             print("😀" + viewcontroller.debugdescription)     } }}

the print function indicates viewcontrollers in fact dismissed memory usage doesn't go down appropriately. started using "debug memory graph". that's 1 example got: enter image description here can see, can't find hints memory leaks related to. can't tell graph.

using app more , more gave me memory leaks related following: corefoundation, libswiftcore.dylib , foundation.

i'm lost , don't know how proceed debugging these leaks there no additional information me pinpoint cause/swift file causing leaks.

ps: i'm not sole developer on project. i'm pretty carrying out work after previous developer , i've seen bad coding practices on place. rewriting isn't feasible option.

in past i've used instruments debug memory leaks. read apple docs figure out how use instruments , pretty helpful -- first section: to memory leaks. found leaks wasn't able figure out using debug memory graph.

instruments user guide: finding memory leaks

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
