我正在使用SDK并使用[[EventStore sharedEventStore] getEventsMatchingQuery:self.aEventQuery];来给我数组作为回报。事件虽然我给出了正确的参数，但它正在崩溃。是代码还是SDK中的问题？
- (void)fetchMonthViewEventWithStartDate:(NSDate*)startDate withEndDate:(NSDate*)endDate {
if (monthViewQueue ==nil) {
monthViewQueue = dispatch_queue_create("monthView Queue",NULL);
}
self.sDate = startDate;
self.eDate = endDate;
// __weak __typeof(&*self)weakSelf = self;
NSDate *eventStartDate = [NSDate getStartDateOfEventForDate:startDate];
NSDate *eventEndDate = [NSDate getEndDateOfEventForDate:endDate];
dispatch_async(monthViewQueue, ^{
[[Manager SharedManager] fetchEventWithStartDate:eventStartDate withEndDate:eventEndDate withSuccessCallBack:^(BOOL success, NSMutableArray *mFilteredArray) {
if(success)
{
dispatch_async(dispatch_get_main_queue(), ^{
_successBlock(mFilteredArray);
});
}else {
_successBlock(nil);
}
} onFailure:^(BOOL status) {
} ifOffline:^(NSString *message) {
}];
});
}
