这些错误是什么以及如何找出这些错误。在我的应用程序中，我正在使用GoogleAnalytics，“结构”，“混合”面板，“核心数据”，并且正在向服务器发送参数并从服务器获取数据。
这是我的代码：
- (IBAction)searchButton:(id)sender {
if (sender == self.searchButton) {
Reachability *networkReachability = [Reachability reachabilityForInternetConnection];
NetworkStatus networkStatus = [networkReachability currentReachabilityStatus];
if (networkStatus == NotReachable) {
UIAlertController * alert = [UIAlertController alertControllerWithTitle : @"Message"
message : @"No Internet!Please Connect and try again."
preferredStyle : UIAlertControllerStyleAlert];
UIAlertAction * ok = [UIAlertAction
actionWithTitle:@"OK"
style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action)
{ }];
[alert addAction:ok];
dispatch_async(dispatch_get_main_queue(), ^{
[self presentViewController:alert animated:YES completion:nil];
});
// NSLog(@"There IS NO internet connection");
} else {
if ([self.selectOptionButton.currentTitle isEqualToString:@"Select Your Option"]) {
UIAlertController * alert = [UIAlertController alertControllerWithTitle : @"Message"
message : @"Please select option."
preferredStyle : UIAlertControllerStyleAlert];
UIAlertAction * ok = [UIAlertAction
actionWithTitle:@"OK"
style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action)
{ }];
[alert addAction:ok];
[self presentViewController:alert animated:YES completion:nil];
} else if ([self.textField.text isEqualToString:@""]) {
UIAlertController * alert = [UIAlertController alertControllerWithTitle : @"Message"
message : @"Please enter number."
preferredStyle : UIAlertControllerStyleAlert];
UIAlertAction * ok = [UIAlertAction
actionWithTitle:@"OK"
style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action)
{ }];
[alert addAction:ok];
[self presentViewController:alert animated:YES completion:nil];
} else {
NSString * key1 = @"Something";
NSString * key2 = @"Something";
NSString * key3;

key3 = @"0";

这些错误的确切含义是什么？如何解决这些错误？
最佳答案
您可以创建BreakPoint来定位错误行。
关于ios - 如何找出这些错误。我的应用崩溃了6次(来自应用分析的报告)？，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/44823524/
