Use UIStackView as if it supports iOS6.
UIStackView is a very handy tool to build flow layout, but it's available only when iOS9+, we've found some great compatible replacements like OAStackView, but we want more:
- Perfect downward compatible, no infectivity, use UIStackView directly as if it's shipped from iOS6.
- Interface builder support, live preview.
- Keep layout constraints as closely as UIStackView constructs.
Import nothing, learn nothing, it just works.
- It will automatically replace the symbol for UIStackView into FDStackView at runtime before iOS9.
// Works in iOS6+, use it directly.
UIStackView *stackView = [[UIStackView alloc] init];
stackView.axis = UILayoutConstraintAxisHorizontal;
stackView.distribution = UIStackViewDistributionFill;
stackView.alignment = UIStackViewAlignmentTop;
[stackView addArrangedSubview:[[UILabel alloc] init]];
[self.view addSubview:stackView];- Interface Builder Support
Set Builds for option to iOS 9.0 and later to eliminate the version error in Xcode:
Now, use UIStackView as you like and its reactive options and live preview:
- Xcode 7+ (For interface builder supports and the latest Objective-C Syntax)
- Base SDK iOS 9.0+ (To link UIStackView symbol in UIKit)
