iOS 7 launched any important modifications to however apps grip the position barroom and navigation barroom, inflicting complications for builders arsenic views abruptly overlapped with these interface components. Galore recovered their cautiously crafted layouts obscured, starring to a little-than-perfect person education. This content stemmed from iOS 7’s clasp of afloat-surface layouts, pushing contented below the position and navigation bars. This article dives into the intricacies of this job, offering factual options and champion practices to guarantee your iOS app’s UI stays pristine and purposeful.
Knowing the iOS 7 Displacement
Anterior to iOS 7, the position barroom occupied a devoted 20-pixel abstraction astatine the apical of the surface, and the navigation barroom resided beneath, leaving the remainder for your app’s contented. iOS 7 blurred these strains, permitting contented to widen below these bars. This created the phantasm of a bigger, much immersive show, however it required builders to accommodate their structure methods. Failing to bash truthful resulted successful overlapping UI parts, obscuring important accusation and diminishing the general person education.
This displacement basically modified the manner builders approached surface existent property. It was nary longer adequate to merely assumption parts comparative to the surface edges. Alternatively, builders wanted to relationship for the adaptable tallness of the position and navigation bars and set their layouts accordingly.
Edges for Prolonged Layouts: The Resolution
1 of the about effectual options to fight this overlapping content lies successful utilizing “edges for prolonged layouts.” This place, launched successful iOS 7, permits you to power however your position interacts with the position barroom, navigation barroom, toolbar, and tab barroom. By mounting the due edges, you tin guarantee your contented respects these scheme UI components and avoids overlapping. For case, mounting edgesForExtendedLayout = UIRectEdgeNone; volition forestall your position from extending below the apical bars.
Present’s a elemental illustration demonstrating however to usage this place:
same.edgesForExtendedLayout = UIRectEdgeNone;
This azygous formation of codification tin resoluteness galore structure conflicts arising from the iOS 7 adjustments. It’s a important implement successful immoderate iOS developer’s arsenal.
Leveraging Apical and Bottommost Structure Guides
Successful summation to edgesForExtendedLayout, iOS 7 launched apical and bottommost structure guides. These guides supply dynamic insets that correspond the abstraction occupied by the position barroom, navigation barroom, toolbar, and tab barroom. By referencing these guides once mounting constraints oregon frames, you tin guarantee your contented stays available and accurately positioned, equal once the tallness of these bars modifications (e.g., throughout a telephone call).
See utilizing these structure guides successful conjunction with Car Format for a much sturdy and adaptable structure. They supply a accordant manner to assumption parts comparative to the available country of the surface, careless of the beingness oregon dimension of scheme UI components. This attack ensures a polished and accordant person interface crossed antithetic iOS gadgets and orientations.
Adjusting Framework Origins
For these not utilizing Car Format, manually adjusting the framework origins of your views gives different path to hole overlapping points. You’ll demand to cipher the mixed tallness of the position and navigation bars and offset your contented accordingly. Piece this attack requires much guide calculation, it affords good-grained power complete your structure.
It’s crucial to retrieve that the tallness of the position barroom tin alteration dynamically, for illustration, once the person is connected a call. So, it’s indispensable to relationship for these variations and replace your framework origins at any time when essential. This dynamic accommodation ensures a accordant person interface careless of the position barroom’s actual tallness.

These sources message successful-extent tutorials and champion practices to aid you maestro iOS improvement. Retrieve, steady studying is cardinal to staying up successful the always-evolving planet of cell improvement.
Question & Answer :
I late downloaded Xcode 5 DP to trial my apps successful iOS 7. The archetypal happening I seen and confirmed is that my position’s bounds is not ever resized to relationship for the position barroom and navigation barroom.
Successful viewDidLayoutSubviews, I mark the position’s bounds:
{{zero, zero}, {320, 568}}
This outcomes successful my contented showing beneath the navigation barroom and position barroom.
I cognize I might relationship for the tallness myself by getting the chief surface’s tallness, subtracting the position barroom’s tallness and navigation barroom’s tallness, however that appears similar pointless other activity.
However tin I hole this content?
Replace:
I’ve recovered a resolution for this circumstantial job. Fit the navigation barroom’s translucent place to Nary:
same.navigationController.navigationBar.translucent = Nary;
This volition hole the position from being framed beneath the navigation barroom and position barroom.
Nevertheless, I person not recovered a hole for the lawsuit once you privation the navigation barroom to beryllium translucent. For case, viewing a photograph afloat surface, I want to person the navigation barroom translucent, and the position to beryllium framed beneath it. That plant, however once I toggle exhibiting/hiding the navigation barroom, I’ve skilled equal alien outcomes. The archetypal subview (a UIScrollView) will get its bounds y root modified all clip.
You tin accomplish this by implementing a fresh place known as edgesForExtendedLayout successful iOS7 SDK. Delight adhd the pursuing codification to accomplish this,
if ([same respondsToSelector:@selector(edgesForExtendedLayout)]) same.edgesForExtendedLayout = UIRectEdgeNone;
You demand to adhd the supra successful your -(void)viewDidLoad methodology.
iOS 7 brings respective adjustments to however you structure and customise the quality of your UI. The adjustments successful position-controller format, tint colour, and font impact each the UIKit objects successful your app. Successful summation, enhancements to motion recognizer APIs springiness you finer grained power complete motion interactions.
Utilizing Position Controllers
Successful iOS 7, position controllers usage afloat-surface format. Astatine the aforesaid clip, iOS 7 offers you much granular power complete the manner a position controller lays retired its views. Successful peculiar, the conception of afloat-surface structure has been refined to fto a position controller specify the structure of all border of its position.
The
wantsFullScreenLayoutposition controller place is deprecated successful iOS 7. If you presently specifywantsFullScreenLayout = Nary, the position controller whitethorn show its contented astatine an surprising surface determination once it runs successful iOS 7.To set however a position controller lays retired its views,
UIViewControlleroffers the pursuing properties:
- edgesForExtendedLayout
The
edgesForExtendedLayoutplace makes use of theUIRectEdgekind, which specifies all of a rectangle’s 4 edges, successful summation to specifying no and each. UsageedgesForExtendedLayoutto specify which edges of a position ought to beryllium prolonged, careless of barroom translucency. By default, the worth of this place isUIRectEdgeAll.
- extendedLayoutIncludesOpaqueBars
If your plan makes use of opaque bars, refine
edgesForExtendedLayoutby besides mounting theextendedLayoutIncludesOpaqueBarsplace to Nary. (The default worth ofextendedLayoutIncludesOpaqueBarsis Nary.)
- automaticallyAdjustsScrollViewInsets
If you don’t privation a scroll position’s contented insets to beryllium robotically adjusted, fit
automaticallyAdjustsScrollViewInsetsto Nary. (The default worth ofautomaticallyAdjustsScrollViewInsetsis Sure.)
- topLayoutGuide, bottomLayoutGuide
The
topLayoutGuideandbottomLayoutGuideproperties bespeak the determination of the apical oregon bottommost barroom edges successful a position controller’s position. If bars ought to overlap the apical oregon bottommost of a position, you tin usage Interface Builder to assumption the position comparative to the barroom by creating constraints to the bottommost oftopLayoutGuideoregon to the apical of bottomLayoutGuide. (If nary bars ought to overlap the position, the bottommost oftopLayoutGuideis the aforesaid arsenic the apical of the position and the apical ofbottomLayoutGuideis the aforesaid arsenic the bottommost of the position.) Some properties are lazily created once requested.
