我不知道为什么我总是遇到这个错误!
再次!

顺便说一句，我使用xcode 7.3
如果这样的代码，不会出错
case 2:
self.recipesImageView.image = UIImage(named: noodles.image)
title = self.noodles.name
`
但是如果这样的代码，“面条”就会变成“小吃”
case 2:
self.recipesImageView.image = UIImage(named: snacks.image)
title = self.snacks.name
然后将是错误:
“线程1:exc_bad_instruction(code = exc_1386_invop，subcode = 0x0)”
下面是我的整个代码

}
*/
}
最佳答案
前任控制人
if segue.identifier == "showRecipesDetail" {
// var obj = segue.destinationViewController as! DetailTableViewCell
if let indexPath = self.tableView.indexPathForSelectedRow {
let destinationController = segue.destinationViewController as! DetailViewController
if segment.selectedSegmentIndex == 0 {
destinationController.recipes = recipes[indexPath.row]
destinationController.category = self.category
print(category)
}
if segment.selectedSegmentIndex == 1 {
destinationController.noodles = noodles[indexPath.row]
destinationController.category = self.category
print(category)
}
if segment.selectedSegmentIndex == 2 {
destinationController.noodles = snacks[indexPath.row]
destinationController.category = self.category
print(category)
}
if segment.selectedSegmentIndex == 3 {
destinationController.noodles = noodles[indexPath.row]
destinationController.category = self.category
}
if segment.selectedSegmentIndex == 4 {
destinationController.noodles = noodles[indexPath.row]
destinationController.category = self.category
}
}
}
}
下面的代码是错误的
if segment.selectedSegmentIndex == 2 {
destinationController.noodles = snacks[indexPath.row] <----this line is wrong
destinationController.category = self.category
print(category)
}
该代码应为
destinationController.snacks = snacks[indexPath.row]
