我的iPad应用程序遇到意外问题,我不确定自己是做错了还是这是正常的设备行为 -
TableViewController
- > didSelectRowAtIndexPath
- > presentModalViewController
modalView
上的取消/保存操作 - > dismissModalViewControllerAnimated
- >工作正常。但是 -
TableViewController
- > didSelectRowAtIndexPath
- > presentModalViewController
modalView
上的操作 - > dismissModalViewControllerAnimated
- > CRASH 我尝试在必要时使用setTranform
修改模态视图 - 它确实会更改视图但不会更改self.interfaceOrientation
值。
我认为解决此问题的正确方法是将self.interfaceOrientation
值修改为90度,但我真的不知道该怎么做 - 除非有更简单的解决方案。
附上调试输出 - 也许它可以帮助......

我的tableView numberOfRowsInSection:
return [iphoneWordPlistUnsorted count];
在.h文件中声明并在viewWillAppear方法上分配:
[super viewWillAppear:animated];
documentsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone)
{
path = [documentsDirectory stringByAppendingFormat:WORDS_PLIST_IPHONE];
self.tableView.sectionHeaderHeight = 63;
self.tableView.rowHeight = 80;
}
else
{
path = [documentsDirectory stringByAppendingFormat:WORDS_PLIST_IPAD];
self.tableView.sectionHeaderHeight = 94;
self.tableView.rowHeight = 120;
}
iphoneWordPlistUnsorted = [[NSMutableArray alloc] initWithContentsOfFile:path];
iphoneWordsPlist = [iphoneWordPlistUnsorted sortedArrayUsingSelector:@selector(localizedCaseInsensitiveCompare:)];
[iphoneWordPlistUnsorted removeAllObjects];
int i;
for (i=0; i < [iphoneWordsPlist count]; i++) {
[iphoneWordPlistUnsorted addObject:[iphoneWordsPlist objectAtIndex:i]];
}
[self.tableView reloadData];

您的iphoneWordPlistUnsorted对象正在被取消分配,内存将被重新分配为其他内容。启用僵尸(在Xcode或在仪器中)运行将帮助您查明错误。
