我刚开始学习ObjectiveC，iOS和Xcode。
我正在关注standford uni教程。我在以下类中定义了在setAndShowDiagnosis:(int)diagnosis实现内部称为PsychologistViewController's的方法。当我调用此方法时，Xcode会说以下内容：
/ Users/matthewwomersley/Documents/developer/Psychologist/Psychologist/PsychologistViewController.m:50:11: Property 'setAndShowDiagnosis' not found on object of type 'PsychologistViewController *'
有什么想法吗？
对不起一个基本问题，但我是MVC的新手

@interface PsychologistViewController ()
@property (nonatomic) int diagnosis;
@end
@implementation PsychologistViewController
@synthesize diagnosis = _diagnosis;
- (void)setAndShowDiagnosis:(int)diagnosis{
self.diagnosis = diagnosis;
[self performSegueWithIdentifier:@"ShowDiagnosis" sender:self];
}
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
if([segue.identifier isEqualToString:@"ShowDiagnosis"]){
[segue.destinationViewController setHappiness:self.diagnosis];
}
}
- (IBAction)flying {
[self.setAndShowDiagnosis:85];
}
- (IBAction)apple {
[self.setAndShowDiagnosis:100];
}
- (IBAction)dragons {
[self.setAndShowDiagnosis:20];
}
@end
最佳答案
[self setAndShowDiagnosis:20];
您可以这样调用函数。您的代码正在尝试访问self的属性
[self.setAndShowDiagnosis:20];
