私は現在、アーカイブまでの目的のcを学習しており、エンコードとデコードに行き詰まりました。
これが私のコードです。
#import <Foundation/Foundation.h>
@interface Foo : NSObject<NSCoding>
@property (copy, nonatomic) NSString *strVal;
@property int intVal;
@property float floatVal;
@end
#import "Foo.h"
@implementation Foo
@synthesize intVal, floatVal, strVal;
-(void) encodeWithCoder: (NSCoder *) encoder
{
[encoder encodeObject: strVal forKey: @"test1"];
[encoder encodeInt: intVal forKey: @"test2"];
[encoder encodeFloat: floatVal forKey: @"test3"];
}
-(id) initWithCoder: (NSCoder *) decoder
{
strVal = [decoder decodeObjectForKey: @"test1"];
intVal = [decoder decodeIntForKey: @"test2"];
floatVal = [decoder decodeFloatForKey: @"test3"];
return self;
}
@end
#import "Foo.h"
int main (int argc, const char * argv[])
{
@autoreleasepool {
Foo *myFoo1 = [[Foo alloc] init];
Foo *myFoo2;
[myFoo1 setStrVal : @"bill"];
[myFoo1 setIntVal : 2];
[myFoo1 setFloatVal: 3.4];
[NSKeyedArchiver archiveRootObject: myFoo1 toFile: @"foo.arch"];
myFoo2 = [NSKeyedUnarchiver unarchiveObjectWithFile: @"foo.arch"];
NSLog(@"%@", [myFoo2 strVal]);
}
return 0;
}
デコードはintとfloatで機能しますが、NSStringオブジェクトをデコードしようとすると。次のエラーが発生しましたが、それについての手がかりがありません...
