在one.m爲什麼該值不會傳遞到下一個TabbarViewController?
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSUInteger row = [indexPath row];
NSString *carNumber = [self.carNumberArrayFromPlistFile objectAtIndex:row];
NSString *engineNumber = [self.engineNumberArrayFromPlistFile objectAtIndex:row];
CarInfo *oneCarInfo = [[CarInfo alloc] initWithCarNumber:carNumber engineNumber:engineNumber];
Two *two = [[Two alloc] initWithNibName:@"Two" bundle:nil];
two.car = oneCarInfo;
[self.navigationController pushViewController:two animated:YES];
[oneCarInfo release];
[two release];
}
在two.h
@interface Two : UITabBarController
{
CarInfo *car;
}
@property (nonatomic, retain)CarInfo *car;
爲什麼在Two.m車上總是空?請幫我解決一下這個。感謝你們!
Two.m:
@interface Two()
@end
@implementation Two
@synthesize car;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
}
- (void)viewDidUnload
{
[super viewDidUnload];
self.car = nil;
}
- (void)dealloc
{
[super dealloc];
}
@end
您是否認爲汽車?你爲什麼從UITabBarController繼承?你是用'car'還是'self.car'來引用汽車? – 2012-08-10 11:52:41
謝謝你的回覆,我很確定我認爲汽車和汽車不是self.car – jxdwinter 2012-08-10 12:03:41
你可以發佈@synthesize的代碼嗎?出於好奇,如果你使用'self.car'而不是'car',會發生什麼? – 2012-08-10 12:08:39
