iPhoneアプリ作成のために

@synthesizeがいらない

クラス内の宣言してない内部メソッドはどこに書いても良い

@ [arr]

@[arr] == [NSArray arrayWithObject:arry]; 
@[obj] == [NSArray arrayWithObject:obj];
@[@"1",@"2"] == [NSArray arrayWithObjects:@"1",@"2", nil];
@[] = [NSArray array]

[@[@"1",@"2"] mutableCopy];

値の取得と代入

@(t)

 @(t) == [NSNumber numberWithInt:t];

@{@"key1",value1,@"key2",value2}

 @{@"key1",value1,@"key2",value2} == [NSDictionary dictionaryWithObjectsAndKeys:value1,@"key1",value2,@"key2",nil];
