objective c - Weakly retaining container class -

-

Objective-C contains a container square that will keep objects in it weakly, I know that NSARRA and NSSite them Will maintain the objects firmly but what is something that they can not be used by any other (and update accordingly)? Is there an inefficient version of this? I need this to keep track of some items, but I do not want to keep them.

et al. Do the job, you want NSPointerArray * PointerArere = [[NSPointerArray alloc] initWithOptions: NSPointerFunctionsWakMemory];

I want to ask if there is another way to see the error label, which has been shown whether we There is no need to fill up with the necessary to use the verifyText command. Here's an example: id: [required] PW: [required] Email: [expected] Dropdown box: [required] If you make test cases, then there is an easy way to make a test case first, and then three error labels will show whether the other fields will not be filled with that. The PW or email from the dropdown box will be shown even if the error is filled with the error label. Before saving that field, I'm just using the verified text, but if there are many conditional requirements like this there is no easy and easy way to create this testcase? Thx If I understand you correctly, If you ignore the required text fields, you are searching for a way to verify that error message. Since I know the Waitfortext command and expect the error message to appear, this command will wait until it expects the err...

I am retrieving a player list from a server and I'm doing stuff with it (later problem related to) . These un-related processes work only if the user name does not have an empty space, but instead of '' the character is '_' I am using this code for loop through character and then find it a '' and, if it is, then it will be replaced with '_' Change, but for some reason it is not known at all? four [] names; (String player name: chatlist) {name = playerName.toCharArray (); For (int i = 0; i & lt; name.length; i ++) {if (name [i] == '') {name [i] = '_'; }} String name S = new string (name); System.out.println (player name + "->" + nameS); } An example of a user name and output is as follows: TestSyear 1 output Testuser_1 Example user output ExampleUser_One Use Replacement All ("\\ s +", "_") . The better way to do this is, otherwise you will change each location wit...
