私はtableviewにデータを保存してロードさせます。2つの警告と2つのエラーがあります。

エラー：

'NSString * __strong'から'BOOL'（別名'signed char'）に割り当てる互換性のないポインターから整数への変換 '
BOOL'（別名'signed char'）から'id'への暗黙の変換はARCでは許可されていません
'BOOL'（別名'signed char'）からタイプ'id'のパラメーター

私の間違いはどこですか？そして、どうすれば修正できますか？

Task.h

#import <Foundation/Foundation.h>

@interface Task : NSObject

@property (nonatomic,strong) NSString *name;
@property (nonatomic,assign) BOOL done;

-(id)initWithName:(NSString *)name done:(BOOL)done;

@end

Task.m

#import "Task.h"

@implementation Task

@synthesize name = _name;
@synthesize done = _done;

-(id)initWithName:(NSString *)name done:(BOOL)done {
    self = [super init];

    if (self) {
        self.name = name;
        self.done = done;
    }
    return self;
}

それ以外の@property (nonatomic,assign) BOOL done;

使用する

@property BOOL done;

また、

    NSString *str = [[NSString alloc] init];
    while ( str = [enumerator nextObject])
    {
        Task *tempTodo = [[Task alloc] init];
        tempTodo.name = str;
        str = [enumerator nextObject];
        tempTodo.done = str;  //Error and warning is here.

strこれが文字列で、これをに割り当てますBOOL。

と

while ( tempTodo = [enumerator nextObject])
{
    [array addObject:tempTodo.name];
    [array addObject:tempTodo.done]; //Eror is here..
}

NSArrayプリミティブ型であるtempTodo.done間のみオブジェクトを含めることができますBOOLsigned char

あなたはそのことを文字列または数字にボックス化することができます

[array addObject:@(tempTodo.done)]; //NSNumber
