When erase container iterator, can I just use iterator++?

Question

for(; iter != endIter; ) {
     if (Some Condition) {
          iter = aMap.erase(iter);
     } else {
          ++iter;
     }
}

for(; iter != endIter; iter++) {
     if (Some Condition) {
          aMap.erase(iter);
     }
}

see code above, I wonder the difference between the two code style since sometimes the posterior one may induce error, for example, andriod build
