由于未捕获的异常“NSRangeException”而终止应用程序，原因:“* -[__NSArrayM objectAtIndex:]:索引 0 超出空数组的范围” * 首先抛出调用堆栈: (0x182caa364 0x181ef0528 0x182c42e9c 0x182b72820 0x100858628 0x100857624 0x18c279670 0x18c279bdc 0x18c31ee74 0x18c3e58b0 0x18 c371910 0x18c4b5c98 0x18c299240 0x18c298bb4 0x18c2988c0 0x18c298960 0x186cfce14 0x1010a528c 0x1010a9ea0 0x182c52544 0x182c5012 0 0x182b6fe58 0x184a1cf84 0x18c2c467c 0x10085e320 0x18268c56c) libc++abi.dylib:以 NSException 类型的未捕获异常终止
最佳答案
if ([[response objectForKey:@"result"] intValue] == 1) {
[_arrRestaurtentTypeList removeAllObjects];
[_arrRestaurtentTypeList addObjectsFromArray:[response objectForKey:@"Main Category"]];
NSDictionary *dictAll = [_arrRestaurtentTypeList lastObject];
if (dictAll) {
[_arrRestaurtentTypeList removeLastObject];
[_arrRestaurtentTypeList insertObject:dictAll atIndex:0];
}
[_collRestaurentTypeList reloadData];
[_tblRestaurent reloadData];
}
用下面的代码改变这一行
if ([[response valueForKey:@"result"] count] >0){
for (NSDictionary *dict in [response valueForKey:@"result"]) {
NSMutableDictionary *newDict = [[NSMutableDictionary alloc] init];
[newDict addEntriesFromDictionary:dict];
[_arrRestaurtentTypeList addObject:newDict];
}
dispatch_async(dispatch_get_main_queue(), ^{
[_tblRestaurent reloadData];
});
