我有一个plist带有Array标题和item0,item1的item2字典来存储我的应用程序的标题和密码。现在我想检查登录过程

进入这里 现在我想检查通过，当我按下提交按钮登录时，项目应该匹配。我尝试了下面的代码，但 xcode 崩溃

-(void)authenticateCredentials 
{ 
NSMutableArray *plistArray = [NSMutableArray arrayWithArray:[self readFromPlist]]; 

for (int i = 0; i< [plistArray count]; i++) 
{ 
 if ([[[plistArray   objectAtIndex:i]objectForKey:@"pass"]isEqualToString:emailTextFeild.text] && [[[plistArray objectAtIndex:i]objectForKey:@"title"]isEqualToString:passwordTextFeild.text]) 
{ 
NSLog(@"Correct credentials"); 
} 

 } 
 }

和

-(NSArray*)readFromPlist
 {
   NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
  NSUserDomainMask, YES); 
  NSString *documentsDirectory = [documentPaths objectAtIndex:0];
 NSString *documentPlistPath = [documentsDirectory stringByAppendingPathComponent:@"XYZ.plist"];

   NSDictionary *dict = [NSDictionary dictionaryWithContentsOfFile:documentPlistPath];

   NSArray *valueArray = [dict objectForKey:@"title"];

   return valueArray;

 }

xcode 崩溃了..请检查 -(void)authenticateCredentials我不正确的地方？

“编辑”当我选择submit按钮时崩溃，它在 nslog 中给出正确的输出但随后崩溃，并带有错误

Agreed with Peter M, you shouldn't store them locally, at least in plain text. It would help a lot if you could post the error stack, so we could see what's failing.

我实际上是我的错..代码在代码中，所以一次又一次地执行..然后崩溃......但是当我Return退出for循环时......它工作正常......小而强大的错误。
