问题 I need to make my little guy (in a UIIamgeView) jump forward and it has to look natural. I want to know is there a way to do it with CoreAnimation (beginAnimation/commitAnimation)? I could do it by setting a point in between in the air but the movement looks not natural :P 回答1: Reading Brad Larson's post, I ended up with a nice function to make my image follow a circle. You need to import QuartzCore framework: #import Here is the code: // Set up path movement CAKeyframeAnimation

问题 I'm trying to load some images in table cells asynchronously using ASINetworkQueue . I just can't figure it out and can't seem to find a good SIMPLE example. The best I can find is this, but its just totally overkill and a little too complicated for me: http://kosmaczewski.net/2009/03/08/asynchronous-loading-of-images-in-a-uitableview/ Does anyone else have any tips/solutions/code for doing this with the ASIHTTPRequest library? 回答1: Here's a class derived from UIImageView which I use, perhaps

问题 Hi Guys I am trying a Image erasing code in my PanGesture I am using code below: UIImage * image = [UIImage imageNamed:@"326d4fb72362a2e44659141cadfc4977.jpg"]; holderView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 235)]; imgForeground = [[UIImageView alloc] initWithFrame:[holderView frame]]; [imgForeground setImage:image]; [holderView addSubview:imgForeground]; UIPanGestureRecognizer *panRecognizer = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(move:)];

问题 I'm drawing round avatar pics, by just applying cornerRadius to a UIImageView 's layer, and also adding a border via borderWith and borderColor . Like so: self.layer.masksToBounds = YES; self.layer.cornerRadius = imageDimension / 2.f; self.layer.borderWidth = 1.f; self.layer.borderColor = borderColor.CGColor; That works great, except for this tiny, but noticeable bleeding of content outside the border, like this: Is there a way to just outset the border by a few 1/10 points, or inset the

问题 UPDATE: Reference #19285042 and submit bug reports to apple Very weird error and not finding anything online. Its saying "BSXPCMessage received error for message: Connection interrupted" I'm just doing some basic filter applications. The error message ONLY occurs if I reassign the UIImageView.image to another UIImage. If I comment out just that line I will not get the error. So if you can think of any reason why this message appears when I assign a filtered image to a UIImageView that would

问题 I have my own subclass of UIButton . I add UIImageView on it and add an image. I would like to paint it over the image with a tint color but it doesn't work. So far I have: - (id)initWithFrame:(CGRect)frame { self = [super initWithFrame:frame]; if (self) { self.backgroundColor = [UIColor clearColor]; self.clipsToBounds = YES; self.circleView = [[UIView alloc]init]; self.circleView.backgroundColor = [UIColor whiteColor]; self.circleView.layer.borderColor = [[Color getGraySeparatorColor]CGColor

问题 I have been trying to mask a UIImage into a circle. I'm using now the code that has been popular on other answers here, but although I do get a circle its edges are very jagged and not smooth. Anyone can help? I do I get a perfect, smooth circle? The code I'm using to create the mask is: (UIImage*) maskImage:(UIImage *)image withMask:(UIImage *)maskImage { CGImageRef imageNoAlpha = image.CGImage; CGColorSpaceRef cs = CGColorSpaceCreateDeviceRGB(); CGFloat width = CGImageGetWidth(imageNoAlpha)

问题 In my app I have a UITextView and a button just below the text view to insert a photo into the UITextView while editing. My requirement is that the user user is able to edit the text within, and insert images when needed. Similar to StackOverflow's app's own UITextView : 回答1: You can add the image view as a subView of UITextView . Create an imageView with image: UIImageView *imageView = [[UIImageView alloc] initWithImage:yourImage]; [imageView setFrame:yourFrame]; [yourTextView addSubview
