计算任意一个UIView相对屏幕的坐标 | HuMin

http://humin.me/archives/128

Posted by Hu Min. 但是很多情况下，我们的UIView可能嵌套了很多层 我在项目中遇到的相对Controller.view就有6层之多 ，并且被嵌套在UIScrollView或者UITableView中，这个时候不可能去拿到每一层嵌套的superview的变量去计算。 计算一个view相对于屏幕(去除顶部statusbar的20像素)的坐标 * iOS7下UIViewController.view是默认全屏的，要把这20像素考虑进去 */ (CGRect)relativeFrameForScreenWithView:(UIView *)v { BOOL iOS7 = [ [UIDevice currentDevice] systemVersion] floatValue] = 7; CGFloat screenHeight = [UIScreen mainScreen].bounds.size.height; if (! 320 view.frame.size.height!

向UITextView发送becomeFirstResponder消息后键盘弹不出来的问题 | HuMin

http://humin.me/archives/138

Posted by Hu Min. ChooseImageTarget performSelectorOnMainThread:@selector(receivePickerImage:) withObject:pickImage waitUntilDone:YES]; - (void)receivePickerImage:(UIImage *)image { [replyTextView becomeFirstResponder]; / do stuff. }. Void)performSelectorOnMainThread:(SEL)aSelector withObject:(id)arg waitUntilDone:(BOOL)wait;这个方法是要在主线程上执行方法，一般需要做UI操作时调用，而调用键盘本身就是UI操作。 If the current thread is also the main thread, and you specify YES for this parameter, the message is delivered and processed immediately.

Author Archives: Hu Min. Posted by Hu Min. 通过I/O将文件读到内存，如发送一个 [UIImage imageWithContentsOfFile:] 消息。 Fast Image Cache的核心就是images table，images table会把所有相当规格大小的图片都加载到一个文件里，当这个文件被读取了一次，它就永远留在内存里(只要程序还在跑)，我们可以任意的读写。 Images table用mmap system call(虚拟内存)将文件映射到内存。 正确的字节对齐方式应该是，每一个bytes-per-row值都是8 pixels*bytes per pixel的整数倍。 比如典型的RGBA图片，一个bytes-per-row值应该是64 pixels*bytes per pixel。 一般来说可以按照以下标准 4 bytes per pixel image width in pixels image height in pixels maximum number of entries。 NSMutableArray *formats = [NS...
