问题 Does anyone know how to insert bullets and do some formatting in a textbox, maybe in a webview (as shown in the print screen below) in iOS 5, XCode 4.3? 回答1: For the UITextView manually add dots and newlines, for example: NSArray *items = [NSArray arrayWithObjects:@"Stack",@"Overflow",nil]; NSMutableString *formattedString = [[NSMutableString alloc] init ]; for (NSString *item in items) [formattedString appendFormat:@"\u2022 %@\n", item]; theTextViewName.text = formattedString; For the

问题 I just installed a software update that I was prompted for, presumable affecting Xcode. Now when I start Xcode, I am presented with a dialog box which states that Xcode must install the Mobile Device Framework before continuing. When I try to do this, after providing my password, it fails with "An unknown error occurred. See the install log for more details." I do not see anything useful in install.log that identifies the problem. I've tried re-installing multiple times and rebooting to no

问题 I'd like to thank all the people that contribute to this website. I am one h*ll of a noob at programming and you all help me out so much. With that said, let's get on with my latest problem! I am creating an app that uses a UIManagedDocument to store a Core Data model for me. I use to create the UIManagedDocument with the following code, but now with Xcode 4.3.2 (The one that updates with the Mac App Store) I have an issue. Here's the code: NSURL *url = [[[NSFileManager defaultManager]

问题 If I start typing in a readonly file in Xcode for the first time, I get prompted with a dialog that basically says the file is locked for editing, and asks me if I want to unlock it. If I choose Unlock, I can continue editing the file. At one point, I got annoyed at this (as I will always want it to unlock), and so I clicked "Do not show this message again", with the expectation that it would remember my choice. However, while I no longer get prompted, it also does not unlock the files

问题 EDIT This problem is related to ASIHTTPRequest. When I remove the ASIHTTPRequest async block, the app does not crash on my device any more. I can run the ASIHTTPRequest code on my device, loaded from Xcode fine. It's just when I upload the archive from TestFlight and try to run it that it crashes. The device crash log shows: Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Codes: KERN_INVALID_ADDRESS at 0x00000058 Crashed Thread: 0 Thread 0 name: Dispatch queue: com.apple.main-thread Thread

问题 I have spent way too much time looking for the files owner icon to click-drag to a text field to assign a variable to that field. Then it hit me that the icon only shows on nib files. Not storyboards. So what is the option to assign a variable to a text field, hard coding? What I am trying to do is show the continuous coords for current location in two text fields on my home screen and update as they move. I have all of that coding done just haven't been able to assign the variable to the

问题 This is in Xcode 4 and it leads me to believe that I can create, and reuse, custom objects. However, I can not find any method of doing so. How do you use this? Does anyone know? 回答1: Short answer: you currently can't use the Custom Objects section to create custom objects. The Custom Objects section contains third-party Interface Builder elements. Older versions of Xcode and Interface Builder supported the creation of custom user interface elements. BWToolkit contains examples of custom
