Nella mia app, ho impostato i vincoli di un UIView in un modo in cui l'altezza viene calcolata dalla sua larghezza utilizzando il vincolo di proporzioni. Funziona perfettamente su iOS8 con tutte le dimensioni dello schermo del dispositivo (3,5, 4, 4,7, 5,5), ma causa l'arresto anomalo dell'app su ogni dispositivo iOS7.interruzioni del vincolo delle proporzioni iOS su iOS7, funziona su iOS8
Suppongo che sia il vincolo di proporzioni, perché se lo sostituisco con un vincolo di altezza fissa, non si blocca più (ovviamente sembra male su alcuni dispositivi).
La traccia dello stack è estremamente lunga, quindi ne sto solo copiando alcune parti.
Grazie in anticipo per il vostro aiuto!
