這很有趣。我有一個通用應用程序。 iPhone和iPad版本都共享相同的類，並且只有不同的xib文件。我經常收到更新iPad版本後的報告，它不會運行，只是崩潰。但是，iPhone版本的更新工作得很好。刪除iPad應用程序，重新啓動和重新安裝將解決啓動時的崩潰問題。在iPad上更新應用程序崩潰
更新與受影響的代碼：
好了，resymbolicating和查看代碼受影響的線路，在這裏後，我覺得是造成問題的所有領域。
我想要的應用要求應用程序是運行問題的第一次，也是唯一的一次，所以在AppDelegate中didFinishLaunchingWithOptions我：
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
if (! [defaults boolForKey:@"notFirstRun"]) {
UIAlertView *firstrun = [[UIAlertView alloc] initWithTitle:@"Sermon Preference" message:@"Do you prefer audio only, or video sermons? (This setting can be changed at any time in the Settings Page.)" delegate:self cancelButtonTitle:nil otherButtonTitles:@"Audio", @"Video", nil];
[firstrun show];
[firstrun release];
[defaults setBool:YES forKey:@"notFirstRun"];
}
然後我在AppDelegate中還有：
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
if (buttonIndex == 0) {
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSString *nope = @"Audio";
[defaults setObject:nope forKey:@"videosermons"];
[defaults synchronize];
}
if (buttonIndex == 1) {
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSString *yup = @"Video";
[defaults setObject:yup forKey:@"videosermons"];
[defaults synchronize]; }
}
我想這些值在設置窗口中改變，所以在設置Ⅰ類有：
- (void)viewDidLoad
{
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSString *currently = [defaults objectForKey:@"videosermons"];
if ([currently isEqualToString:@"Audio"]) {
segment.selectedSegmentIndex = 0;
}
if ([currently isEqualToString:@"Video"]) {
segment.selectedSegmentIndex = 1;
}
NSString *firstName = [defaults objectForKey:@"firstName"];
if (firstName == nil) {
}
else {
myTextField.text = firstName;
}
NSURL *url = [NSURL URLWithString:@"http://www.bellavenue.org/worship.html"];
self.content = [NSString stringWithContentsOfURL:url];
[super viewDidLoad];
}
的崩潰日誌說，導致崩潰的行是：
if ([currently isEqualToString:@"Audio"]) {
什麼一切是怎麼回事，是造成崩潰只在iPad上，只更新已經安裝的以前版本的時候，而不是全新安裝？

嘗試獲取崩潰報告，或者至少控制檯日誌，以尋找線索。更少的是隨機猜測。 –
不幸的是，我在iTunes Connect中沒有崩潰報告，並且我的iPad上沒有任何舊版本來執行更新並在xcode中運行 – user717452
也許應用商店正在提供損壞的二進制文件。它每隔一段時間就會這樣做。 – CodaFi
