获取堆栈错误,原因不明

[英]Getting Stack Error, Unexplained

我有这个代码

-(IBAction) generateFlashNow:(id)sender{

[textField resignFirstResponder];
NSString *string1 = textField.text;
//NSString *string2 = [string1 stringByReplacingOccurrencesOfString:@"" withString:@","];
NSArray *arrayOfLetters = [string1 componentsSeparatedByString:@","];

NSLog(@"Log Array :%@", arrayOfLetters);

//NSArray *imageArray = [[NSArray alloc] init];

NSLog(@"Log First Letter of array: %@",[arrayOfLetters objectAtIndex:0]);

runLoopTimes = [arrayOfLetters count];
runLoopTimes = (runLoopTimes -1);
NSLog(@"Letters:%d", runLoopTimes);

int timesThroughLoop;

while (runLoopTimes > 0) {
    NSLog(@"loopedy Loop");

    NSString *LetterString = [NSString stringWithFormat:@"%@", [arrayOfLetters objectAtIndex:indexTimes]];
    timesThroughLoop --;
    NSLog(@"letter String : %@", LetterString);
    indexTimes ++;

    if (runLoopTimes == 0) {
        return; 
    }
}

NSLog(@"done");


}

当我在文本字段“ s,a,m”中键入内容时,我得到此日志报告

而且我不知道我在做什么错,因此我们将不胜感激。

干杯,山姆

您永远不会减少runLoopTimes内的runLoopTimes 因此它将无限期地循环。 最终indexTimes不在数组的末尾。
