This issue is occurring when user is opening the app from background.

care to share some code? and perhaps you are doing something you should not if the crash is inside the component ... — PetrV, Jul 24 '15 at 11:11
You are missing line numbers for your own calls, likely an issue with the dSYM generation in your build process. Also you should always show the complete crash report and also the relevant source code. — Kerni, Jul 24 '15 at 11:20
You try to send a `rangeOfCharacterFromSet:` to an NSMutableArray (the pointer in your code is probably not of type NSMutableArray but NSString or NSMutableString). So Look for occurrences of the method and make sure the object really is an NSString and not an NSMutableArray. — HAS, Jul 11 '16 at 16:39

tl;dr it is an memory issue, the string is not valid anymore.

you can simple reproduce the stacktrace with the following steps / code:

// 1) create a property to enforce the memory issue
@property (nonatomic, assign) NSString* dumpString

now we just trick the compiler a little bit...

// 2) create an invalid "string"object, in this case, a view :)
NSDictionary* dict = @{@"key": [[UIView alloc] init]};
// 3) because objectForKey: will return an id, the runtime has no idea that it is no string
self.dumpString = [dict objectForKey:@"key"];
// 4) here is your crash, when we set the value to the textfield, the textfield tries to sanitize the string and runs into an invalid memory layout
self.textField.text = self.dumpString;
