我遇到运行时错误:线程1:EXC_BreakPoint(cod = EXC_I1386_BPT,子码= 0x0)
我没有在Xcode中设置任何断点。从调试器,错误是由PrepareForSegue停止一个线程“swift_dynamicCastClassUnconditional”
BarTableViewController1类
@IBAction func solve_PressedBar(sender: AnyObject) {
self.performSegueWithIdentifier("SolveBar", sender: sender)
}
override func prepareForSegue ( segue: UIStoryboardSegue, sender: AnyObject!) {
if (segue.identifier == "SolveBar") {
var svcBar = segue.destinationViewController as BarTableViewController2
for items in textField1 {
length.append((items as NSString).floatValue)
}
for items in textField2 {
youngMod.append((items as NSString).floatValue)
}
for items in textField3 {
diameter.append((items as NSString).floatValue)
}
for items in textField4 {
forceBarWall.append((items as NSString).floatValue)
}
self.funcForceBarWall()
println("variables are from TableViewController2")
println(self.length)
println(self.youngMod)
println(self.forceBarWall)
println(self.diameter)
svcBar.length2 = self.length
svcBar.youngMod2 = self.youngMod
svcBar.diamter2 = self.diameter
svcBar.forceBarWall2 = self.forceBarWall
println("testing from bar viewcontroller1")
}
}
}
答案 0 :(得分:0)
我先看看这里:
var svcBar = segue.destinationViewController as BarTableViewController2
检查故事板并确保segue确实连接到BarTableViewController2项目。有时在拖动时,我会偶然将segue连接到其他东西。
