reactjs - What's the cleanest way to get my react web app using push notifications on iOS? -

doing rapid prototyping app running in browser , on ios/android/etc. @ point may have build native versions, not necessary @ moment. we need native push notifications working @ least on ios (which isn't supported browser, may getting worked on future release supports progressive web apps). looking cleanest solution issue still allows keep our single code base , won't bloat our working environment. from cursory investigation looks reactnative require device specific branching. may fine down road, wait until through of our initial prototyping. is phonegap/cordova way go? speed on device isn't big issue keeping our code base clean can move fact it's in webview doesn't matter much. haven't touched phonegap in ages, can isolate code base cleanly wrapper? another option thinking of writing lightweight ios wrapper webview , basic bindings handle push notification aspect. not sure if tricky though, , may have hidden pitfalls. would love recommendations c...

switch off html wrapping of errors in nginx -

i use nginx on ubuntu forward requests spring boot -driven api server. api returns body 4xx , 5xx errors, client application consumes. e.g. in api code might return: { "message": "blah" } however nginx seems wrap errors html , embeds response within them. there way disable behavior? , there way en masse (i.e. 4xx , 5xx errors, without explicitly writing them out error_page example) similar question , accepted answer here , seems bit of hack. i'm sure there's better way of doing this... edit: config looks this: server { listen 80; server_name my.domain.com; location / { proxy_pass http://127.0.0.1:9001; } } you need add error_page directive inside location server { listen 80; server_name my.domain.com; location / { error_page 404 = 404; proxy_pass http://127.0.0.1:9001; } } what cancel error_page previous directives set @ http block. , pass result client is....

How to create a pointer in Swift? -

i'm working swift 3. i have c syntax : int myvar; int *pointer = &myvar; so modifying pointer or myvar same exact same thing. don't know if makes difference, in case myvar array containing elements of class , pointer pointer 1 element of array. (assuming understand you're asking for....) try following code in playground. should print "99" 3 times. class row { var rownumber = 0 } var rows = [row]() let testrow = row() testrow.rownumber = 1 rows.append(testrow) let selectedrow = rows[0] selectedrow.rownumber = 99 print(testrow.rownumber) print(selectedrow.rownumber) print(rows[0].rownumber) by default, there's no copying of objects part of assignment statement. if struct, different. adding bit completeness: if want similar effect scalar values instead of objects, swift supplies various types of wrappers. let intpointer = unsafemutablepointer<int>.allocate(capacity: 8) // should 1, not 8 according comment...

c# - How can I check if all the rows in DataGridView is not null? -

i had problem quite while. what planned if of cell[0] has value, trigger event. if there null , it'll change value of textbox . here's code: private void button1_click(object sender, eventargs e) { (int = 0; < datagridview1.rows.count; i++) { if (datagridview1.rows[i].cells[0].value.tostring() == null) { textbox.text = "null"; break; } else { messagebox.show("no null"); } } but whats happening here example have 3 rows in datagridview , if first row not null lunch messagebox . want messagebox triggered when of row's cells not null. try this: bool anynull = false; (int = 0; i<datagridview1.rows.count; i++) { if (datagridview1.rows[i].cells[0].value.tostring() == null) { textbox.text = "null"; anynull = true; break; } } if (!anynull) messagebox.show("");

apache - 2 rewrite rules not working together -

i have rewrite rule product detail page instead of url being /product-detail.php?id=3765 it instead: /blue-jeans this rewrite rule: rewriterule ^([0-9a-za-z-]+)$ product-detail.php?slug=$1 [nc,l] however, need 1 regional dealers. add .htaccess, product detail rule stops working in blank page displayed when navigating product. how can them both work? rewriterule ^([0-9a-za-z-]+)$ dealers.php?slug=$1 [nc,l] it's because matching regex identical, , first 1 of them matches , you're done. need wrapping php script can sort out or have other token in regex limit scope. example products under /products , dealers under /dealers, , like: rewriterule ^/dealers/([0-9a-za-z-]+)$ /dealers.php?slug=$1 [nc,l] rewriterule ^/products/([0-9a-za-z-]+)$ /products.php?slug=$1 [nc,l]
