重複應用代理調用方法

Question

所以我有我的AppDelegate方法試圖設置一個對象在ViewController方法。我的AppDelegate看起來是這樣的：

if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) 
    { 
    //Grab a reference to the UISplitViewController 
    UISplitViewController *splitViewController = (UISplitViewController *)self.window.rootViewController; 

    PatientDetailViewController* patientDetailViewController = [splitViewController.viewControllers lastObject]; 
    splitViewController.delegate = patientDetailViewController; 


    //Grab a reference to the masterviewcontroller and get the first patient in the list. 
    UINavigationController *patientNavController = [splitViewController.viewControllers objectAtIndex:0]; 
    PatientMasterTableViewController *patientMasterViewController = (PatientMasterTableViewController *)[patientNavController topViewController]; 

    Patient* firstPatient = [[patientMasterViewController patientArray] objectAtIndex:0]; 

    //Set it as the detailviews patient. 
    [patientDetailViewController setPatient:firstPatient]; 

    //Set the detail's as the left's delegate. 
    patientMasterViewController.delegate = patientDetailViewController; 
    } 

return YES; 
} 

，並設置對象的方法是這樣的：

-(void)setPatient:(Patient *)patient 
{ 

if (![self.patient isEqual:patient]) 
    { 
    self.patient = patient; 

    //Update the UI to reflect the new patient selected from the list. 
    [self refreshUI]; 
    } 
} 

是我遇到的問題是，setPatient方法將被調用不停直到程序崩潰，我不知道爲什麼。任何人都可以對此有所瞭解嗎？

Answer 1

此：

-(void)setPatient:(Patient *)patient 
{ 
if (![self.patient isEqual:patient]) 
    { 
    self.patient = patient; 

    //Update the UI to reflect the new patient selected from the list. 
    [self refreshUI]; 
    } 
} 

應該是：

-(void)setPatient:(Patient *)patient 
{ 
    _patient = patient; 
    [self refreshUI]; 
}
