Hi, In my application, i'm using a view(say X), that has a webview, along with few other controls. On click of a button, i'm creating a tabview item & setting its view property to X. On clicking "Cancel" button, i'm removing this tabview item. Application is crashing when these steps are done - 1. Press button(displays tabview item) 2. Click cancel(removes tabview item) 3. Press the button pressed in step 1 again. There is an issue with the webview. Say on step 1, the webview object was WebView: 0x10564bc00. When i press the same button again(step 3), i'm getting this message in console - malloc: *** error for object 0x10564bc00: pointer being freed was not allocated *** set a breakpoint in malloc_error_break to debug However now the webview object is changed to some 'xyz' value. Any suggestion on how to fix this? I'm using xcode 4.5 & ARC is enabled.
