我使用此代码将事件添加到 iOS 上的日历应用程序

int i = 0;

for(Schedule *sche in scheduleArray){ 
EKEventStore *eventStore=[[EKEventStore alloc] init];
EKEvent *addEvent=[EKEvent eventWithEventStore:eventStore];
addEvent.title=@"hello";
addEvent.startDate=[NSDate date];
addEvent.endDate=[addEvent.startDate dateByAddingTimeInterval:600];  
[addEvent setCalendar:[eventStore defaultCalendarForNewEvents]];  

addEvent.alarms=[NSArray arrayWithObject:[EKAlarm alarmWithAbsoluteDate:addEvent.startDate]];

NSError *err;
[eventStore saveEvent:addEvent span:EKSpanThisEvent error:&err];
if (err == nil) {
    NSString* str = [[NSString alloc] initWithFormat:@"%@", addEvent.eventIdentifier];

    NSLog(@"String %d: %@",i, str);
}
else { 
    NSLog(@"Error %@",err);
}
i++;     
}

我想用我之前在 scheduleArray 中保存的数据添加所有事件，我在 scheduleArray 中有 86 个对象，但似乎我只在日历中添加了大约 82 个事件。这是我的日志结果：

我不知道为什么会出现这些错误？如何将我的所有活动添加到日历中？
