Question

我正在尝试使用dismissModalViewController:Animated:来驳回我的观点，但无论我尝试什么，它都不会解雇它。您可以看到我尝试在底部的hideSplash方法中发布视图。请，如果有人可以提供帮助，将不胜感激。我的代码发布在下面：

#import "SplashViewController.h"

@implementation SplashViewController

- (void) didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
}

- (void) viewDidUnload {

}

- (void) dealloc {
    [super dealloc];
}

-(void) showSplash {
    modalViewController = [[UIViewController alloc] init];
    modalViewController.view = modelView;
    [self presentModalViewController:modalViewController animated:NO];
    [activityIndicator startAnimating ];
    //[self bigcalculation];
    //[self performSelector:@selector(hideSplash) withObject:nil afterDelay:2.0];
}

- (void) viewDidAppear:(BOOL)animated {
    NSLog(@"View Did Appear");
    [self bigcalculation];
}

- (void) bigcalculation {
    NSLog(@"Big Calc Start");
    for (int i = 0; i <= 648230; i++) {
        for (int j = 0; j <= 1200; j++) {

        }
    }
    NSLog(@"Big Calc End");
    [self performSelector:@selector(hideSplash) withObject:nil];
}

- (void) hideSplash {
    NSLog(@"Hide");
    //[self dismissModalViewControllerAnimated:NO];
    //[[self parentViewController] dismissModalViewControllerAnimated:YES];
    [[self modalViewController] dismissModalViewControllerAnimated:YES];
    NSLog(@"End Hide");
}

@end

Answer 1

模态视图控制器不负责解雇。这种负担放在调用modalViewController的视图控制器上。

尝试更换：

[[self modalviewController] dismissModalViewControllerAnimated:YES];

与

[self dismissModalViewControllerAnimated:YES];

Answer 2

尝试使用它：

[self.parentViewController dismissModalViewControllerAnimated:NO];

Answer 3

我找到了解决方案以防其他人遇到此问题的行

[self performSelector:@selector(hideSplash) withObject:nil];

应该是

[self performSelector:@selector(hideSplash) withObject:nil afterDelay:0.0];

dismissModalViewControllerAnimated函数不解除视图
