嗨,我是Ios的新手,在我的应用程序中,当我们使用社交网络登录时,我试图将一个视图控制器移动到另一个视图控制器,就像我已经用twitter注册了我的应用程序
根据我的代码,当我们点击Twitter登录按钮时,Twitter登录页面将被加载到屏幕上,当我们点击该按钮时,我们会在Twitter登录页面上显示“AuthorizedApp”按钮我们获得用户详细信息
我们获得该用户详细信息后,我想移动另一页
注意: -
我的主要目的是当我们点击“AuthorizedApp”按钮然后我想移动另一页请帮帮我一个
根据我的代码,我得到例外: - 警告:尝试在窗口层次结构中显示其视图!
#import "ViewController.h"
#import "FHSTwitterEngine.h"
#import "ViewController1.h"
#import "AppDelegate.h"
@interface ViewController ()<FHSTwitterEngineAccessTokenDelegate>
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
[[FHSTwitterEngine sharedEngine]permanentlySetConsumerKey:@"XXXXXXXXXXXXXX" andSecret:@"XXXXXXXXXXXXXXXXXXXXXXXXXX"];
[[FHSTwitterEngine sharedEngine]setDelegate:self];
[[FHSTwitterEngine sharedEngine]loadAccessToken];
//google plus login button
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button addTarget:self
action:@selector(loginOAuth)
forControlEvents:UIControlEventTouchUpInside];
// [button setImage:[UIImage imageNamed:@"twitter-icon.png"] forState:UIControlStateNormal];
button.frame = CGRectMake(10, 390, 300, 30);
button.backgroundColor = [UIColor redColor];
CALayer * d = [button layer];
[d setMasksToBounds:YES];
[d setCornerRadius:20];
[self.view addSubview:button];
}
- (void)loginOAuth {
UIViewController *loginController = [[FHSTwitterEngine sharedEngine]loginControllerWithCompletionHandler:^(BOOL success) {
NSLog(success?@"L0L success":@"O noes!!! Loggen failure!!!");
NSLog(@"User name ---->>>%@",FHSTwitterEngine.sharedEngine.authenticatedUsername);
NSLog(@"User id ------> %@",FHSTwitterEngine.sharedEngine.authenticatedID);
[self movetoanotherview];
}];
[self presentViewController:loginController animated:YES completion:nil];
}
-(void) movetoanotherview{
ViewController1 *dvc = [self.storyboard instantiateViewControllerWithIdentifier:@"ViewController1"];
[dvc setModalTransitionStyle:UIModalTransitionStyleCoverVertical];
[self presentViewController:dvc animated:YES completion:nil];
}
答案 0 :(得分:0)
我认为这种情况正在发生,因为您正在创建一个视图控制器。视图控制器将在其范围的末尾与块一起消失。
尝试将dvc声明为.h文件中的属性(或.m文件的顶部)
@property (strong, nonatomic) ViewController1 *dvc;
Then do this instead:
self.dvc = [self.storyboard instantiateViewControllerWithIdentifier:@"ViewController1"];
[_dvc setModalTransitionStyle:UIModalTransitionStyleCoverVertical];
[self presentViewController:_dvc animated:YES completion:nil];
