pointers - dealloc or releasing best practice in objective-c? -


मैं बस ऑब्जेक्ट्स को बस के रूप में जारी करता हूं: 

  [myObj release];

मैंने दूसरों को देखा है: 

  [myObj release]; MyObj = शून्य;

क्या बाद वाला अधिक फायदेमंद है क्योंकि अब उस पॉइंटर का कोई संदर्भ नहीं होगा?

यह सुनिश्चित करने के लिए है कि अन्य लगातार संदेश जो myObj पर भेजे जा सकते हैं अपवाद नहीं फेंकें। संदेश को शून्य पर भेजना संभव है उद्देश्य-सी

अन्यथा, myObj अभी भी मेमोरी एड्रेस को इंगित करता है जहां यह है और इसे एक्सेस करने से BAD_ACCESS त्रुटि हो सकती है ।

Thanks Zone Since you are updating the image, it should lie with the image (style of image as part) such as if the image is by default Is hidden, so I try the following Using R can choose to make it visible with toggleproperty1. DataTrigger binding = "{binding toggleproperty}" value = "1" & gt; & lt ; Setter Property = "Visibility" value = "View" />

wpf - Converter stops filter working -

I'm trying to display the file name in a listbox, taken from a special directory. They are stored in an ObservableCollection of FileInfo Object: Public supervision & lt; FileInfo & gt; Project Files {Get (empty (selected folder == empty); DirectoryInfo D = New Directory Info (SelectedFolder); if (!
