有关遍历的项目总结

1、项目中遍历的第一种方式

for (UnitComModel * name in unitModel.comp ) {  
      [arrName addObject:name.cName];  
 }
NSString * cName = [arrName componentsJoinedByString:@"、"]; 
 self.facNameLabel.text = cName;

2、第二种方式

NSMutableArray *arrM = [NSMutableArray new];
for (NSDictionary *dic in arr) { 
   [arrM addObject:dic[@"facName"]]; 
}
 NSString *facNames = [arrM componentsJoinedByString:@"、"];
self.productFacLabel.text = facNames;
