阅读更多关于 iOS and Xcode: incompatible type error when setting delegate and datasource in a UITableView

问题 I'm trying to make an app programmatically that includes a UITableView that makes a list of items based on the files in the app's Documents directory. I have been able to make the files be read into an array _filepathsArray , but the compilation crashes and Xcode throws warnings when I try to use the array to fill the table. Xcode points out problems with the following lines: _tableView.delegate = self; _tableView.dataSource = _filepathsArray; Both of these throw "semantic issues". The first

问题 With reference to this previous SO question , I corrected my mistake & changed the iterators to be of same "vector type" i.e. I replaced the line auto startIter = table.begin(); with auto startIter = tabTypeIterVector[0]; in the for loop in AccessTableIteratorsVector() function. wrt below code, however, I'm still getting the "Debug assertion failed, vector iterators incompatible error, when this line is hit in for loop itloop !=-endIter typedef vector<vector<string> tableDataType; vector

问题 I need this method to go through my ArrayList myZip, find whether or not there is an integer in there that matches int zip, then go and find the ZipCode that is equal to intZip; if there is no match then return null. public ZipCode findZip(int zip) { for (int i = 0; i < myZips.size(); i++) { if (zip == myZips.get(i)) return myZips.get(i);} return null; } Any ideas? Here's the ZipCode Class: public class ZipCode { private int zipCode; private String city; private String state; private double

问题 I've seen some SO links wherein similiar error was seen & was suggessted to use const reference to the vector as they were copying the vector (pass by value) but in my scenario I'm using the same vector (no pass by value). But seeing this issue. WRT below code, I'm seeing the error Debug assertion failed window pops up & I get vector iterators incompatible error in runtime when the line itloop !=-endIter is hit. typedef vector<vector<string> tableDataType; vector<tableDataType::Iterator>
