POUsing NSMutableDictionary as backing store for properties
text
Body
copied!<p>I am looking for a shorthand way of setting my properties directly to an NSMutableDictionary that is a instance variable. ie:</p> <p>KVCModle.h:</p> <pre><code>@interface KVModel : NSObject { NSMutableDictionary * data; } @property(nonatomic,assign)NSString * string1; @property(nonatomic,assign)NSString * string2; @end </code></pre> <p>KVCModel.m</p> <pre><code>#import "KVModel.h" @implementation KVModel -(id)init { self = [super init]; if(self) { data = [[NSMutableDictionary alloc] init]; } return self; } -(NSString *)string1 { return [data objectForKey:@"string1"]; } -(NSString *)string2 { return [data objectForKey:@"string2"]; } -(void)setString1:(NSString *)_string1 { [data setObject:_string1 forKey:@"string1"]; } -(void)setString2:(NSString *)_string2 { [data setObject:_string2 forKey:@"string2"]; } -(void)dealloc { [data release]; [super dealloc]; } @end </code></pre> <p>I have tried to override <code>setValue:ForKey:</code> and <code>valueForKey:</code>, but those aren't called, they allow you to directly set properties without using the property syntax.</p> <p>I have made preprocessor macros to make this work in the past, but I am not interested in typing at all, and would like to avoid as much of it as I can in the future. Is there a way to make this work that I am not familiar with?</p> <p>I have thought about using NSManagedObject, but I am not sure if I can get what I want out of that. <strong>EDIT:</strong> <a href="http://objectivelybetter.com/tests/keyValueTest.zip" rel="nofollow" title="source">source</a></p>
