问题 I have an app that utilizes the video camera so the screen cannot dim. Inhibiting the screen from dimming works fine like so: - (void)applicationDidBecomeActive:(UIApplication *)application { [[UIApplication sharedApplication] setIdleTimerDisabled:YES]; } However when the app is closed and enters the background, setting the IdleTimer back to NO is not working. The screen stays on forever on the home screen. This is how I am trying to accomplish this. - (void)applicationWillResignActive:

问题 I created a textField through code using the following code UITextField *txtObj=[UITextField alloc]initWithFrame:CGRectMake(88,100,80,33)]; I am getting the textfield as i planned, but the text we type in that text field seems to appear in the top area of text but not in bottom.I tried to align it but i got tired. Can anyone tell me what's the solution 回答1: it should be: txtObj.contentVerticalAlignment = UIControlContentVerticalAlignmentBottom; This property is inherited from the UIControl

问题 I'm creating an app that will have a number of variants. These variants will be controlled by a few strings in multiple Localizable.strings files. However, 90% of the strings will remain the same. I'd like to have it so that each of the unique Localizable.strings files imports the "master" one, so that I don't have to go through each of the app variant files when I want to change a common string. Is this possible? 回答1: Two alternatives: Use custom wrapper functions around NSLocalizedString

问题 I have problem with "Would you like to save this password" dialog. When it pop-up and user go to home screen and back to app, dialog disappears and he is not able to raise keyboard when to touch in to textfield. Its only "working" like this on iOS 13. On iOS 12 it is working OK, because when user come back to app, dialog is still there. Then he can save password or tap not now and start typing. Any ideas how to solve this? Its probably some kind of iOS 13 bug. 回答1: Problem As OP writes: if

问题 I have to use Google Map for my iPhone project and I'am using GMSPolygon to draw a polygon but How can I fill everywhere on my map except the interior of the polygon. Like the image below.

Here is example code, but problem is that I can`t create polygon to cover whole Earth. First approach is to create 4 polygons for each quarter. PGeoCountry is a struct

问题 I'm trying to build a working simulator build from xcodebuild. Compilation works but the final product won't run on the simulator when installed via WaxSim. If I build through the Xcode GUI then the final product installs without issue from WaxSim. My question is, how can I see the exact xcodebuild command line that xcode is using to build a working simulator build. I just need to copy that into my shell script but it's proving elusive. I did a find in the build logs from xcode but there's no
