我在我的应用程序中设置了一个子视图“弹出窗口”，如果用户点击子视图弹出窗口上的按钮，我想显示一个 navController。到目前为止，我已经设置了按钮，但是如果我点击按钮，navigationController 会出现在我的弹出窗口下！？我已经搜索了一些解决方案，但我没有找到任何解决方案。整个控制器实际上显示在一个文件夹中，您可以在这里找到：https ://github.com/jwilling/JWFolders所以 viewDidLoad 属于文件夹和 rootview。我试图将其作为弹出窗口的子视图，但这也不起作用。有谁知道如何治疗？我也以编程方式设置了弹出窗口和导航控制器。提前致谢。
我的代码：
导航控制器设置：
- (IBAction)dothis:(id)sender {
MWPhotoBrowser *browser = [[MWPhotoBrowser alloc] initWithDelegate:self];
// Set browser options.
browser.wantsFullScreenLayout = YES;
browser.displayActionButton = YES;
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:browser];
[self presentModalViewController:navController animated:YES];
NSMutableArray *photos = [[NSMutableArray alloc] init];
MWPhoto *photo;
photo = [MWPhoto photoWithFilePath:[[NSBundle mainBundle] pathForResource:@"star" ofType:@"png"]];
photo.caption = @"The star is soo beateful...";
[photos addObject:photo];
self.photos = photos;
}
- (MWPhoto *)photoBrowser:(MWPhotoBrowser *)photoBrowser photoAtIndex:(NSUInteger)index {
if (index < _photos.count)
return [_photos objectAtIndex:index];
return nil;
}
- (NSUInteger)numberOfPhotosInPhotoBrowser:(MWPhotoBrowser *)photoBrowser {
return _photos.count;
}
弹出代码：
-(IBAction)mehr:(id)sender {
//the popup size and content
UIView *contentView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 280, 440)];
CGRect welcomeLabelRect = contentView.bounds;
welcomeLabelRect.origin.y = 20;
welcomeLabelRect.size.height = 40;
UILabel *welcomeLabel = [[UILabel alloc] initWithFrame:welcomeLabelRect];
//an simple activityindicator
activityindi = [[UIActivityIndicatorView alloc]initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhite];
activityindi.frame = CGRectMake(120, 200, 40, 40);
[activityindi startAnimating];
[contentView addSubview:activityindi];
//The Imageview
CGRect infoimagerect = CGRectMake(5, 70, 270, 200);
UIImageView *infoimage = [[UIImageView alloc] initWithFrame:infoimagerect];
//and the Button
cubut = [UIButton buttonWithType:UIButtonTypeCustom];
[cubut addTarget:self
action:@selector(dothis:)
forControlEvents:UIControlEventTouchUpInside];
[cubut setTitle:nil forState:UIControlStateNormal];
cubut.frame = CGRectMake(5, 70, 270, 200);
//retrieving data from parse.com
PFQuery *query = [PFQuery queryWithClassName:@"My-Application"];
[query getObjectInBackgroundWithId:@"My-ID"
block:^(PFObject *textdu, NSError *error) {
if (!error) {
//hide the Button if there is no image
cubut.hidden=YES;
//the headline of popup
UIFont *welcomeLabelFont = [UIFont fontWithName:@"copperplate" size:20];
welcomeLabel.text = [textdu objectForKey:@"header"];
welcomeLabel.font = welcomeLabelFont;
welcomeLabel.textColor = [UIColor whiteColor];
welcomeLabel.textAlignment = NSTextAlignmentCenter;
welcomeLabel.backgroundColor = [UIColor clearColor];
welcomeLabel.shadowColor = [UIColor blackColor];
welcomeLabel.shadowOffset = CGSizeMake(0, 1);
welcomeLabel.lineBreakMode = UILineBreakModeWordWrap;
welcomeLabel.numberOfLines = 2;
[contentView addSubview:welcomeLabel];
//the image from parse
if (!error) {
PFFile *imageFile = [textdu objectForKey:@"image"];
[imageFile getDataInBackgroundWithBlock:^(NSData *data, NSError *error) {
if (!error) {
UIImage *image = [UIImage imageWithData:data];
infoimage.image = image;
infoimage.contentMode = UIViewContentModeScaleAspectFit;
//show the button when the image appears
cubut.hidden = NO;
[contentView addSubview:infoimage];
//stop the activityindicator
[activityindi stopAnimating];
}
}];
}
} else {
//show some text
welcomeLabel.text = @"No connection!";
[welcomeLabel sizeToFit];
//hide the button
cubut.hidden = YES;
[contentView addSubview:infoLabel];
//stop the activityindicator
[activityindi stopAnimating];
}
}];
//add the content to the KNGModal view
[[KGModal sharedInstance] showWithContentView:contentView andAnimated:YES];
}
我的 viewDidLoad
- (void)viewDidLoad
{
but.hidden = YES;
PFQuery *query = [PFQuery queryWithClassName:@"myapp"];
[query getObjectInBackgroundWithId:@"Rgq5vankdf"
block:^(PFObject *textu, NSError *error) {
if (!error) {
but.hidden = NO;
but.color = [UIColor colorWithRed:0.90f green:0.90f blue:0.90f alpha:1.00f];
} else {
//if failure
but.hidden = YES;
mol.text = @"No Connection";
}
}];
[super viewDidLoad];
}
