uiimageview

问题 I am using EGOPhotoViewer to load up a bunch of images from the s3. They are shown in thumbnails first in table view, so when a user clicks 5th row of image, it loaded the image into image viewer starting at 5 of 20 . and this is working smoothly in ios 6. but when I installed ios 7 and run my app.I got an error. it fails to load the clicked image. when user click 5th row of image,image viewer load the very 1st image starting at 1 of 20. i am using this much of code. - (void)tableView:

问题 This is actually a follow up to this question - How can I display image on fullscreen when user taps on my UIImage in Swift? I managed to add a tap listener to my uiimageview, but now I would like to expand it when user clicks it. I have an iboutlet for that photo: @IBOutlet weak var requestPhoto: UIImageView! and then the listener so far prints this string: func tapHandler(sender: UITapGestureRecognizer) { if sender.state == .Ended { print("photo tapped") } } Now instead of printing the

问题 I have some code which works nicely and acts like a menu appearing when you click a button. I just want to animate slightly. So when it appears, it appears to bounce in. Here's the code which shows it [UIView beginAnimations:@"theAnimation" context:NULL]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(yourAnimationHasFinished:finished:context:)]; [UIView setAnimationDuration: 0.3]; CGAffineTransform moveUp = CGAffineTransformMakeTranslation(0, -20);

问题 I have several different buttons, which are all segued modally to another ViewController that contains several UIimage views. What I'm trying to do is to create an IBAction for each button that will set images to the UIimageViews in the other ViewController. (my UIimageViews are @property(nonatomic, retina) and I have tried multiple codes like "setImage" and many others with no success) I wass wondering if this could be done by using tags? THANKS!!! 回答1: Use Delegates delegate. On button

问题 i have a user-defined class of type CircularDynamicUIView. it is in an array the encompass several views like 'buttonviews, uiimageviews,scrollviews and others. how to programmatically within a loop to detect this user-defined class. for example: using if-statement how to check if this class is the class created or developed by the user and not the one that already created by objective-c. 回答1: As @rmaddy noted in comments, you cannot explicitly differentiate between, for example, your custom

问题 I've got it so far that I can move, scale and rotate all the objects, but the multiple objects all move together. I want them to move seperate. I guess I have to change the objectatIndex to 1, but it just crashes. I've used the following code: - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { NSArray *allTouches = [touches allObjects]; UITouch* t; if([[event allTouches] count]==1){ if (CGRectContainsPoint([Birdie frame], [[allTouches objectAtIndex:0] locationInView

问题 The share icon (image is white) below is 114x128 pixels. Fixing the height in Interface Builder to 23 pixels with AutoLayout then using Aspect Fit for the Content Mode does not change the frame rectangle, though. This causes issues with alignment since if you want the icon 15 pixels from the trailing edge, it's now hard to do so. One option is to manually set the aspect ratio (i.e., 114/128) as an AutoLayout constraint within IB. But this is extremely fragile. If you change the image

问题 I have set image's content mode aspect fit. Now issue is that, when I'm drawing line on image, that time image's content mode set scaletofill and my image stretched. So I want solution for when I'm drawing line on image, image content mode remain same. U can download myproject from this link. I'm using following code: - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { if(self.tempImage.image==nil) { return; } colorPicker.hidden = YES; UITouch *touch = [touches anyObject];
