1.vfl的正确编写格式
- NSDictionary *dict1 = NSDictionaryOfVariableBindings(_boxV,_headerL,_imageV,_backBtn,_doneBtn);
- NSDictionary *metrics = @{@"hPadding":@5,@"vPadding":@5,@"imageEdge":@150.0};
- NSString *vfl = @"|-hPadding-[_boxV]-hPadding-|";
- NSString *vfl0 = @"V:|-25-[_boxV]";
- NSString *vfl3 = @"V:|-vPadding-[_headerL]-vPadding-[_imageV(imageEdge)]-vPadding-[_backBtn]-vPadding-|";
