目標C類 - 警告問題

Question

我有一個代表模型

myModel.h

#import <CoreData/CoreData.h> 

@property (nonatomic, retain) NSString * prop1; 
@property (nonatomic, retain) NSString * prop2; 
@property (nonatomic, retain) myModel2 * model; 

myModel.m

@dynamic prop1; 
@dynamic prop2; 
@dynamic model; 

myModel2.h

一個simeple類

#import <CoreData/CoreData.h> 

@property (nonatomic, retain) NSString * prop1; 
@property (nonatomic, retain) NSString * prop2; 
@property (nonatomic, retain) myModel * model; 

我的Model2.m

@dynamic prop1; 
@dynamic prop2; 
@dynamic model; 

someclass.m

myModel *myVar = (code that populates); 

[myVar setProp1:@"test"]; // I get a myVar may not respond to -setprop1; 
[myVar setProp2:@"test"]; // NO Warning everything oK. 

而且，模型包含循環引用...

Answer 1

的約定是setProp1 :,不setprop1：

不知道爲什麼你沒有看到第二個警告。順便說一句，你的財產是一個NSNumber *，你試圖在那裏傳遞一個int。
