Question & Answer :
I person an app that helps iOS8 and future, constructed successful Xcode 7 and I americium utilizing a XIB for a Motorboat Surface (I bash not person motorboat photos). The position comprises a azygous UILabel with the app interpretation, and 2 UIImageViews with pictures that are some immediate successful Photographs.xcassets: A brand and a splash representation.
The UILabel and the brand representation look appropriately once I motorboat the exertion, however the splash representation does not if I tally the app connected an iPad Aerial 2 with iOS9. I person examined connected an Aerial and a Mini moving iOS8, and iOS9 simulators for iPad 2, iPad Aerial, and iPad Aerial 2 and the representation seems accurately successful each of these.
I ran any basal troubleshooting to seat if I may fig retired what is going connected however I haven’t been capable to lick it and the lone quality I tin seat betwixt the representation that’s running and the 1 that’s failing is once I added it to the belongings…
Present’s a rundown of what I cognize:
- The UIImageView for the splash representation is successful the accurate spot, astatine the accurate measurement. I tin archer this due to the fact that I fit its inheritance colour to greenish conscionable to brand certain. The position is location, however the representation does not look. Truthful I’m assuming that the position is not to blasted.
- Mounting the UIImageView for the splash representation to besides usage the emblem representation makes the emblem representation look successful the accurate spot for the position. This besides leads maine to presume that the position is not to blasted.
- The UIImage that I americium utilizing successful the splash representation position is utilized elsewhere successful the app and seems good successful these another views (the brand representation is besides utilized elsewhere successful the app and seems good). Truthful I’m assuming that the representation is legitimate and having it look successful another views is not a job.
- I’ve confirmed that the settings of the UIImages for the brand and splash successful the xcassets record are the aforesaid. They are fit to Cosmopolitan, Immoderate width and tallness, aggregate standard elements, rendered arsenic default. Location is 1 quality - the emblem has 1x, 2x and 3x scales piece the splash representation lone has 1x and 2x, however I person besides tried utilizing UIImages with lone 1x, and 1x and 2x values successful the UIView and they activity (if they have been added to the task any clip agone).
- Including different representation of a antithetic measurement oregon format (PNG and JPG) to my xcassets and utilizing that UIImage successful the UIImageView for the splash representation besides fails to show.
- Including different UIImageView to the XIB record and allocating it a UIImage that was already successful the xcassets plant, the representation seems successful the loading surface.
- Copying and renaming the representation information utilized for the brand and including them to the task past utilizing that UIImage successful the splash position besides fails to show.
- I person tried cleansing the task, restarting the improvement device, and deleting the app from the Aerial 2 and reinstalling it conscionable successful lawsuit that was a job.
These past 3 steps pb maine to accept that location’s any content with photos added last a definite component successful the task record’s life. Piece I up to date to Xcode 7 yesterday, the splash representation was primitively added successful Xcode 6, however the emblem representation (besides added successful Xcode 6) was added any months earlier.
I’ve appeared complete the json information for the emblem representation and splash representation and they look to person the aforesaid format. I’ve besides trawled done the pbxproj record trying for variations and I tin’t seat immoderate.
Truthful I was questioning if anybody had immoderate thought wherefore the motorboat surface mightiness not show these fresh pictures I’m including connected the Aerial 2 particularly? Another questions I’ve been speechmaking done relating to photos not showing each look to associate both to Motorboat Photos, oregon to pictures successful XIB information that person related lessons, neither of which appears applicable present.
Bend it disconnected and past connected once more.
Earnestly, restart the instrumentality — that’s what fastened it for maine.
Present’s what didn’t activity:
- Cleansing DerivedData.
- Cleansing the task.
- Uninstalling the app from the instrumentality.
- Restarting Xcode.
- Restarting the machine.
Older observations:
Conscionable similar the others, it:
- Plant good successful the Simulator
- Utilized to activity connected the gadgets (iPhone 5S, iPad Aerial)
- Nary codification modifications (verified through git reset –difficult Caput), but stopped running.
What I retrieve triggering the archetypal physique wherever it stopped running was unplugging the iPhone piece it was runnning. (Not certain if it’s associated.)
Nevertheless, the git reset not fixing it (mixed with each the cleanable steps not running) tells maine it this essential beryllium getting cached location other. Rather perchance successful 1 of the .gitignored information? (I’m utilizing Git disregard record for Xcode initiatives)
1 workaround that labored for 1 UIImageView (successful the UIView that has 3) however not for the others was placing the representation into an .xcassets record. Reverting to the plain representation record did not back the hole. (Truly feels similar a caching mistake.)
Replace: Seat apical — restarting the instrumentality is what fastened it. I acquire the feeling the incorrect bitmap information is being cached connected the instrumentality itself.
