iphone-sdk-3.0

Has anyone done this before? It would be most appreciated if I can see any examples you may have. There's really no code to demonstrate, he lists both calls there. Heres's an example, for what it is worth: NSError *error; [SFHFKeychainUtils storeUsername:@"fred" andPassword:@"mypassword123" forServiceName:@"myService" updateExisting:YES error:&error]; NSString *storedPassword = [SFHFKeychainUtils getPasswordForUsername:@

Here is the code: - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { if ([touches count] == 1) { // code } else { // code } } When I simulate the double tap with the Option key in simulator, the code always chooses the first part of my if statement, as if there were only 1 touch received. Why am I not receiving both touches? The multipleTouchEnabled property needs to be set to YES before the view can accept multitouch. 来源： https://stackoverflow.com/questions/2287102/how-to-enable-multiple-touches-in-an-ios-app

I'd like to add custom controls to the mediaPlayer control view much as this asker: Add Custom Controls to MoviePlayer However, the solution posted in the above question is depreciated in 3.0. Does anyone know of a way to do this with the new SDK?

I've been using touchesBegan and touchesEnded to no avail. Any help is appreciated. look at this sample project http://developer.apple.com/iphone

GuardMalloc: Allocations will be placed on 16 byte boundaries. GuardMalloc: - Some buffer overruns may not be noticed. GuardMalloc: - Applications using vector instructions (e.g., SSE or Altivec) should work. GuardMalloc: GuardMalloc version 18 (gdb) all of the sudden those guardmalloc messages appears in the console window. What's the cause and how do I get rid of it? Mostly because the application behaves weird after those appear. I guess you have intentionally enabled GuardMalloc to find memory errors? If so, these appear simply because GuardMalloc is being used (as shown by http:/

How to display iPhone free memory in a UILabel ? and I would like to ask, how to free up memory using iPhone SDK? FYI, I'm using iPhone SDK 3.1.2 with xcode 3.2.1 (Mac OS X Snow Leopard). There is no direct access to this information in the SDK, and apps are not allowed to mess around with the OS the way you're suggesting. You're in your own little box; Apple expects you to stay there. When you ask questions that include "the system," you are probably outside of your box. That said, there are some tricks you can use. You can allocate increasingly-large blocks of memory until you receive
