我正在尝试将 NSDictionary
数据放入 tableView
。但是当只有一个值时我会遇到问题。
这里,有一个“上传”计数返回 8(但它应该返回 1),如果有多个“上传”计数返回“上传”的数量,因为它应该在第一种情况下。
NSDictionary *jsonDictionary = aDicLog;
NSMutableArray *tableData = jsonDictionary[@"multimedia"][@"uploads"][@"upload"];
int count = [tableData count];
NSLog(@"COUNT: %i", count);
表格
- (NSInteger)tableViewUITableView *)tableView numberOfRowsInSectionNSInteger)section
{
return [tableData count];
}
单元格
- (UITableViewCell *)tableViewUITableView *)tableView cellForRowAtIndexPathNSIndexPath *)indexPath
{
//App Crashes in this line
NSDictionary *ldUpload = [tableData objectAtIndex:indexPath.row];
...
return cell;
}
异常(exception),有一个“上传”:
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSDictionaryM objectAtIndex:]: unrecognized selector sent to instance
字典如下所示:
这是应用崩溃的时间只需一次“上传”)
Printing description of tableData:
{
FileName = {
text = "IMG_0510.MOV";
};
status = {
text = 2;
};
Event = {
text = Q;
};
Date = {
text = "9/9/2016 11:01:58 AM";
};
Publicacion = {
text = "Example";
};
Seccion = {
text = Sistemas;
};
idMultimedia = {
text = 1136;
};
text = "";
}
这是应用运行良好的情况有多个“上传”)
Printing description of tableData:
<__NSArrayM 0x7a49dc90>(
{
FileName = {
text = "1-FB5A9792.MOV";
};
status = {
text = 4;
};
Event = {
text = Test;
};
Date = {
text = "9/7/2016 9:06:21 AM";
};
Publicacion = {
text = "Example";
};
Seccion = {
text = Sistemas;
};
idMultimedia = {
text = 993;
};
text = "";
},
{
FileName = {
text = "2-FB5A9793.MOV";
};
status = {
text = 4;
};
Event = {
text = Test;
};
Date = {
text = "9/7/2016 9:06:21 AM";
};
Publicacion = {
text = "Example";
};
Seccion = {
text = Sistemas;
};
idMultimedia = {
text = 994;
};
text = "";
},...
我正在使用 XMLReader将 XML 转换为 Dictionary
,然后将上述数据传递给 tableData
XML
<multimedia>
<uploads>
<upload>
<id>1136</id>
<Date>9/9/2016 11:01:58 AM</Date>
<FileName>IMG_0510.MOV</FileName>
<status>2</status>
<ublicacion>Example</Publicacion>
<Seccion>Sistemas</Seccion>
<Event>Q</Event>
</upload>
</uploads>
</multimedia>
当只有 1 个“上传”和 n 个“上传”的情况下,我如何返回 1 而不是 8?
您可以在生成tableData数组的基础上检查对象类型是Dictionary
还是NSArray
。
id uploadsObj = jsonDictionary[@"multimedia"][@"uploads"][@"upload"];
if ([uploadsObj isKindOfClass:[NSDictionary class]]) {
NSMutableArray *tableData = [NSMutableArray arrayWithObjectNSDictionary*)uploadsObj];
}
else if ([uploadsObj isKindOfClass:[NSArray class]]) {
NSMutableArray *tableData = [NSMutableArray arrayWithArrayNSArray*)uploadsObj];
}
关于ios - NSInvalidArgumentException 有一个字典,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/39728785/
