Ios 如何将这些dict添加到一个数组中

如何在单个数组中添加这些字典…

在数组中添加对象（字典），如下所示：-

NSMutableDictionary *dict = [NSMutableDictionary dictionaryWithDictionary:@{@"Name": self.txt1.text , @"Roll No.":self.txt2.text,}];

NSMutableDictionary *dict1= [NSMutableDictionary dictionaryWithDictionary:@{@"Name":self.txt3.text , @"Roll No.":self.txt4.text}];

NSMutableDictionary *dict2 = [NSMutableDictionary dictionaryWithDictionary:@{@"Name":self.txt5.text , @"Roll No.":self.txt6.text}];

NSMutableDictionary *dict3 = [NSMutableDictionary dictionaryWithDictionary:@{@"Name":self.txt7.text, @"Roll No.":self.txt8.text}];

//在其他视图控制器（根据注释）NSDictionary中显示值：-

遍历数组，获取值，在标签中显示值（IBOutlets）

就这样

试试这个

attributes = [[NSMutableArray alloc] init];
[attributes addObject: dict.mutableCopy];
[attributes addObject: dict1.mutableCopy];
[attributes addObject: dict2.mutableCopy];
[attributes addObject: dict3.mutableCopy];

使用NSArray文本

NSMutableArray *arrDict = [NSMutableArray alloc]initWithObjects:@{@"Name" : self.txt1.text , @"Roll No" : self.txt2.text},@{@"Name" : self.txt7.text, @"Roll No" : self.txt8.text} nil

在下一个ViewController中，您可以通过循环获取此词典

NSArray *arrDict =@[@{@"Name" : self.txt1.text , @"Roll No" : self.txt2.text},@{@"Name" : self.txt7.text, @"Roll No" : self.txt8.text} ];

@[dict1、dict2、dict3]如何显示通过txtfield输入的该名称和卷号（在其他标签中）viewcontroller@swativerma，将阵列传递给其他视图控制器。遍历数组并显示值（名称、卷号）。检查。如何在下一个ViewController的标签中显示此名称和通过txtfield输入的卷号您需要将此数组传递给下一个ViewController，并使用循环获取此字典。并使用键的值为标签指定值

NSMutableArray *arrDict = [NSMutableArray alloc]initWithObjects:@{@"Name" : self.txt1.text , @"Roll No" : self.txt2.text},@{@"Name" : self.txt7.text, @"Roll No" : self.txt8.text} nil

NSArray *arrDict =@[@{@"Name" : self.txt1.text , @"Roll No" : self.txt2.text},@{@"Name" : self.txt7.text, @"Roll No" : self.txt8.text} ];

for (NSDictionary *dicUser in arrDict) {
        // this dictionary which contained by arrDict
        UILabel *lblName = [dicUser objectForKey:@"Name"];
        UILabel *lblRollNumber = [dicUser objectForKey:@"Roll No"];

    }
