我正在自定义Parse登录视图,我用库创建了模糊的背景,但现在我可以使用UIVisualEffectView。因为我有一个类作为PFLoginViewController
的委托,所以我决定继承UIVisualEffectView并将其作为我的委托。问题是并非我的所有登录视图都显示出来。我知道我的框架设置正确。这是我的代码,可以更好地了解我所谈论的内容。
-(id)initWithEffect:(UIVisualEffect *)effect {
self = [super initWithEffect:effect];
[self setUpUserViews];
return self;
}
- (void)setUpUserViews {
NSLog(@"Setting Up View");
CGRect size = CGRectMake(0, 0, self.frame.size.width, self.frame.size.height);
//Initialize login and sign up views
_loginView = [[PFLogInViewController alloc] init];
_signUpView = [[PFSignUpViewController alloc] init];
//Set their delegates to this view controller
[_loginView setDelegate:self];
[_signUpView setDelegate:self];
//Set fields for sign up view
[_signUpView setFields:PFSignUpFieldsEmail | PFSignUpFieldsUsernameAndPassword | PFSignUpFieldsSignUpButton];
//Set sign up view for login view
[_loginView setSignUpController:_signUpView];
//Set up login view
_loginView.view.frame = size;
_loginView.view.backgroundColor = [UIColor clearColor];
[_loginView.logInView setLogo:[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"banner.png"]]];
//Set Login Button
[_loginView.logInView.logInButton setBackgroundImage:[UIImage imageNamed:@"orange.png"] forState:UIControlStateNormal];
[_loginView.logInView.logInButton setBackgroundImage:[UIImage imageNamed:@"orangeDown.png"] forState:UIControlStateHighlighted];
//Set login text color
[_loginView.logInView.logInButton setTitleColor:[UIColor orangeColor] forState:UIControlStateNormal];
[_loginView.logInView.logInButton setTitleColor:[UIColor whiteColor] forState:UIControlStateHighlighted];
//Set sign up button
[_loginView.logInView.signUpButton setBackgroundImage:[UIImage imageNamed:@"green.png"] forState:UIControlStateNormal];
[_loginView.logInView.signUpButton setBackgroundImage:[UIImage imageNamed:@"greenDown.png"] forState:UIControlStateHighlighted];
//Set sign up button text color
[_loginView.logInView.signUpButton setTitleColor:[UIColor colorWithRed:0.0 green:1.0 blue:0.0 alpha:0.6] forState:UIControlStateNormal];
[_loginView.logInView.signUpButton setTitleColor:[UIColor whiteColor] forState:UIControlStateHighlighted];
//Set dismiss button
[_loginView.logInView.dismissButton setImage:nil forState:UIControlStateNormal];
[_loginView.logInView.dismissButton setImage:nil forState:UIControlStateHighlighted];
[_loginView.logInView.dismissButton setBackgroundImage:nil forState:UIControlStateHighlighted];
[_loginView.logInView.dismissButton setBackgroundImage:nil forState:UIControlStateNormal];
[_loginView.logInView.dismissButton setBackgroundImage:[UIImage imageNamed:@"dismiss.png"] forState:UIControlStateHighlighted];
[_loginView.logInView.dismissButton setBackgroundImage:[UIImage imageNamed:@"dismiss.png"] forState:UIControlStateNormal];
//Set forgotten button
[_loginView.logInView.passwordForgottenButton setImage:[UIImage imageNamed:@"forgot.png"] forState:UIControlStateNormal];
[_loginView.logInView.passwordForgottenButton setImage:[UIImage imageNamed:@"forgot.png"] forState:UIControlStateHighlighted];
[_loginView.logInView.passwordForgottenButton setBackgroundImage:nil forState:UIControlStateNormal];
[_loginView.logInView.passwordForgottenButton setBackgroundImage:nil forState:UIControlStateHighlighted];
//Use custom method for showing sign up view
[_loginView.logInView.signUpButton removeTarget:nil action:NULL forControlEvents:UIControlEventAllEvents];
[_loginView.logInView.signUpButton addTarget:self action:@selector(customViewMethod) forControlEvents:UIControlEventTouchUpInside];
//Set up sign up view
_signUpView.signUpView.backgroundColor = [UIColor clearColor];
//Set sign up button
[_signUpView.signUpView.signUpButton setImage:[UIImage imageNamed:@"green.png"] forState:UIControlStateNormal];
[_signUpView.signUpView.signUpButton setImage:[UIImage imageNamed:@"greenPress.png"] forState:UIControlStateHighlighted];
[_signUpView.signUpView.signUpButton setBackgroundImage:nil forState:UIControlStateNormal | UIControlStateHighlighted];
//Present login view
[self.contentView addSubview:_loginView.view];
}
这是我所获得的截图。左上角有一个X.这是登录视图的一部分:
以下是它应该是什么样子的截图:
答案 0 :(得分:0)
问题已经解决了。问题是事情很快就会从内存中释放出来,导致有nil
代表。
